Hiking in the Ardennes: the Best Areas, Day Hikes and Multi-Day Routes

The Ardennes are an old, rounded mountain range. Summits sit roughly between 300 and 700 meters, there are no glaciers, no altitude sickness and no technical climbing. What there is instead: broad stretches of deciduous and coniferous forest that fill the view, rivers that have cut deep into limestone and slate over millennia, rock outcrops from which a bend in the valley lies below you like a map, and in the Hautes Fagnes an open, windy peat plateau with wooden boardwalks that keep you above the bog.

This is arguably the most accessible multi-day walking in Western Europe. There is no altitude to acclimatize to, the waymarking is excellent, villages sit within a day's walk of one another, and the trails are open far earlier and later in the year than anything in the Alps. If you want the rhythm and satisfaction of a long-distance trek without the logistics of a mountain range, walking in the Ardennes delivers exactly that.

It helps to know that "the Ardennes" as a hiking region crosses national borders. Wallonia, the Luxembourg Oesling and the adjoining German Eifel belong together as a landscape: the same plateau, the same slate ridges, the same deep valleys. The border is administrative; the landscape ignores it. The highest point in Belgium, the Signal de Botrange, lies in the Hautes Fagnes on the eastern edge of the Ardennes plateau.

The Belgian Ardennes cover roughly the Walloon provinces of Luxembourg, Liège and Namur. The well-known gateways are La Roche-en-Ardenne, Durbuy, Bouillon, Malmedy, Spa, Dinant, Vielsalm and Stavelot on the Belgian side. On the Luxembourg side lie the starting points for most multi-day routes: Ettelbruck, Kautenbach, Clervaux and Vianden belong to the Oesling, the northern highland of the Grand Duchy that runs seamlessly into the Belgian Ardennes.

By air and rail. For travelers coming from further afield, Brussels and Luxembourg are the two natural entry points, and both have international airports with onward rail connections. Brussels is also served directly by high-speed trains from Paris, London and Amsterdam. From either city you continue by train into the region, which is the simplest way to reach the trailheads.

By train our Luxembourg starting points are excellent. The railway line through the Alzette and Ourthe valleys serves Ettelbruck, Kautenbach and Clervaux directly. Public transport within Luxembourg is free. For current journey times and connections, check the rail operator's own website, which keeps timetables and fares up to date.

By car you have more freedom to reach the smaller Belgian gateways, and rental cars are easy to pick up at either airport. But a car is convenient rather than necessary: the Escapardenne routes were designed around public transport, and you can start, finish and leave the region by train.

The Ardennes are not one uniform block. Each sub-region has its own character, its own rhythm and its own kind of walker who feels most at home there. Below are the seven most distinctive areas, from east to west and from north to south.

Hautes Fagnes and the Hoëgne valley

The Hautes Fagnes are the most open and expansive part of the Ardennes: a high plateau where the peat is meters thick, the wind has free rein and the horizon sits far away. Wooden boardwalks keep you above the wet sphagnum moss. The Baraque Michel is the traditional resting point in the middle of the plateau. On the edge of the fens, the Hoëgne valley drops away to the west: a river walk past rocks, small waterfalls and wooden footbridges that shows walking beside water at its best. The Hoëgne is the most loved day hike in the province of Liège and starts and finishes in Jalhay or at the parking area at Roquez.

Ourthe valley around La Roche-en-Ardenne and Durbuy

La Roche-en-Ardenne is the hiking capital of the Belgian Ardennes. The Ourthe winds through the valley here in broad loops while the slopes climb steeply to rock outcrops with long views over the bends below. Durbuy, a little further upstream, is built the same way: narrow lanes, a rocky ridge above the town and waymarked day loops that bring you back to a terrace in two to four hours. This is the area where most day walkers and weekend walkers first get to know the Belgian Ardennes.

Amblève and Warche: Coo, Stavelot and Malmedy

North of the Hautes Fagnes, the Amblève and the Warche drop down through wooded gorge country. At Coo the waterfalls tumble down, the best known in the Belgian Ardennes. Stavelot and Malmedy are characterful small towns with a rich abbey history. The trails here run alternately through forest, along streams and across open slopes, and are quieter than the more popular spots around La Roche.

Semois around Bouillon, Rochehaut and Botassart

The Semois is the most picturesque river in the Belgian Ardennes. At Botassart the river wraps around an elongated hill so completely that it looks as though an island is floating in the forest, a view that appears on every list of the finest sights in the Ardennes. Rochehaut looks out over a broad river bend, and Bouillon sits tucked in below its castle. The paths here are more adventurous, the valleys deeper and the sun lower than in the north.

Lesse and Viroin around Dinant and Han-sur-Lesse

The western part of the Belgian Ardennes is limestone country. The reefs rise straight up along the Lesse and the Meuse. Han-sur-Lesse has the best-known caves in the country. Trails run alongside and through limestone cliffs, with views that are fundamentally different from the slate hills further east. Less crowded than people expect, certainly outside the summer season.

The Gaume: the most southerly and quietest corner

The Gaume, the southernmost tip of the province of Luxembourg, is one of the hidden gems of the Belgian Ardennes. The climate is sunnier and milder, the landscape more open, and the villages look almost French and Burgundian. Trails along the Viroin and through the hills around Florenville and Virton are barely busy. Anyone looking for something other than the classic Ardennes atmosphere will find their corner here.

The Luxembourg Oesling and the Mullerthal

The Oesling, the Luxembourg part of the Ardennes plateau, consists of slate ridges cut through by deep river valleys. Kautenbach, Clervaux and Vianden are the loveliest villages. The neighboring Mullerthal, also called Little Switzerland, surprises with narrow rock passages, moss-green ravines and sandstone that looks quite unlike the Belgian side. Both areas are easy to reach by train and form the starting point for most of the multi-day Ardennes hiking trails that Bookatrekking offers.

A multi-day hike in the Ardennes works differently from a hut-to-hut trek in the Alps. There are no mountain huts: you sleep in small hotels and guesthouses in the villages along the route, breakfast is ready every morning and there is somewhere to eat every evening. Your luggage travels ahead of you, so you walk with a day pack. That makes a self-guided walking vacation in the Ardennes more accessible than many mountain treks, while the continuous stages through forest and valley still give you the feeling of a real long-distance walk.

At Bookatrekking we offer four multi-day routes in the Ardennes, each as a self-guided, independently walked package.

Escapardenne Lee Trail, 5 days. This multi-day trek through the Luxembourg Oesling starts in Ettelbruck and finishes in Kautenbach, 58.1 kilometers in total over three walking days. The longest day is 21.5 kilometers with 750 meters of ascent. The path follows the slate valley of the Sûre, climbs past rock faces and drops down to quiet river villages. This is the shortest of our Ardennes routes and therefore the logical choice for a first trek in the region or a long weekend on the trail. The Lee Trail carries the Leading Quality Trail - Best of Europe certification, which sets high standards for the quality of the paths, the waymarking and the public transport connections.

Escapardenne Eislek Trail, 7 days. The Eislek Trail runs in seven days from Kautenbach via Clervaux and Houffalize to La Roche-en-Ardenne, 106.4 kilometers in total. You set off in Luxembourg and finish in the Belgian Ardennes, literally crossing the border on foot. The longest day is 24 kilometers with 810 meters of ascent. The route passes one deep valley after another, forest villages, a monastery, reservoirs and the spectacular rock wall of Le Hérou near Nadrin. This is the most varied trip in our range for anyone who wants a full week of trekking combined with changing landscapes. The Eislek Trail carries the same Leading Quality Trail certification as the Lee Trail and can also be walked independently as a multi-day hike in the Ardennes with overnight stays.

Full Escapardenne Trail, 10 days. If you want to walk the Lee and the Eislek Trail back to back, book the complete traverse from Ettelbruck to La Roche-en-Ardenne in ten days. That is 164.5 kilometers in total, with a longest day of 24 kilometers. This is the most complete trek in the Ardennes for anyone with the time to walk the whole line from the Luxembourg Oesling to the Belgian Ardennes in one go.

Ardennes Trail (Transardennaise), 9 days. If you specifically want to walk across the Belgian Ardennes, choose the Transardennaise: nine days from La Roche-en-Ardenne to Bouillon, 152.9 kilometers in total. The longest day is 28.2 kilometers and the shortest 15.7 kilometers; the route alternates open forest tracks with villages, ridges and river crossings straight through the provinces of Luxembourg and Namur. This is the most extensive trek through the Belgian Ardennes itself and the right choice for anyone skipping the Luxembourg side to head deep into the Walloon backcountry.

The Escapardenne is the name of the continuous long-distance route that links the Luxembourg Oesling with the Belgian Ardennes: the Lee Trail and the Eislek Trail together. The route carries the Leading Quality Trail - Best of Europe certification, an award with strict requirements for the trail itself, the surrounding nature and accessibility. Walkers choose the Escapardenne because it combines two of the finest sub-regions in one continuous trek, reachable by train and with daily luggage transfer.

Not every visitor has several days. The Ardennes are just as good for a day or a weekend: almost every village has a waymarked loop of a few hours that you can walk without any preparation. From La Roche-en-Ardenne a handful of well-marked loops set off to explore the Ourthe valleys. From Bouillon you can lead yourself into the forests of the Semois hills. Around Coo and Stavelot, walks along the Amblève are popular. In the Hautes Fagnes, boardwalks carry you over the peat without needing boots.

The Hoëgne is the best-loved waterside walk in the region. The little river runs through a wooded valley, the paths cross wooden footbridges and pass small rock faces, and children can scramble about by the waterfalls. The walk can be done in half a day or a full day, depending on the distance you choose.

Hiking in the Ardennes with children works best on day walks: short loops from a village, a waterfall as the goal, a rock outcrop to clamber up. The boardwalks of the Hautes Fagnes also work well for younger children because there is no elevation gain. The Mullerthal on the Luxembourg side has narrow rock clefts and moss-green paths that children love. For older children with walking experience, the shorter multi-day options are also possible: two or three consecutive days with a night on the way gives a first real taste of trekking without dragging on too long.

For a two-day walk with an overnight stay, pick one of the waymarked long-distance paths and walk two stages of it. That does not have to be one of our booked products: the region has dozens of marked routes with places to stay in the villages. If you would rather not organize anything yourself, book one of our shortest packages and let us handle the accommodation and logistics.

Hiking in the Ardennes is not high-mountain trekking. There are no technical climbing sections, no fixed ropes on exposed ground and no snow during the walking season. But anyone who thinks "it's only the Ardennes" and expects an easy stroll is mistaken. The hills are modest in height, but the climbs and descents follow one another constantly: up over a forested ridge, steeply down into a river valley, back up to the next plateau. That rhythm is manageable in a single day with normal fitness; over several consecutive days the accumulation of climbs adds up. People whose legs are not used to it notice on day three that their calves have opinions.

After rain the forest paths are slippery and muddy. Waterproof hiking boots with good tread are not a luxury but a basic requirement, even in summer. Trekking poles help on wet descents, certainly on the steeper sections of the Eislek Trail.

For children, day walks in the Ardennes are perfectly doable, especially if you choose a route with a clear goal: a waterfall, a rock outcrop, a castle. On the shorter multi-day options, children with walking experience and good fitness keep up well; the stages do ask for a certain amount of determination.

The hardest trips in the Ardennes are the longest continuous treks, not because of technical difficulty but because of the chain of walking days. The Transardennaise, with a longest day of 28.2 kilometers, asks the most base fitness of anything in our range.

One of the strengths of the Ardennes is that you can walk here all year round, although every season shows a different face.

April and May are the months of the young beech forest: light falls in long shafts through a canopy that has not closed yet, the streams run full with meltwater and the slopes are in bloom. The paths can still be damp after the winter rain, but this is the quietest of the beautiful periods.

June to August brings the longest days and the warmest weather. The forest gives shade, but well-known villages like La Roche-en-Ardenne and Bouillon also draw plenty of non-walking tourists in July and August. On the trails themselves it is quieter than in the villages.

September and October are the best months for most experienced walkers. The weather is more settled than in spring, the paths are dry, the forests turn from green to gold and copper, and the crowds in the villages have ebbed away. If you have the choice, go in September or early October.

November to March is the quiet period. The forests are bare, the days short and the paths muddy. In the Hautes Fagnes the boardwalks can be closed in hard frost or snow. Day walks in this period can be exceptionally beautiful in mist or snow, but for a multi-day hike in the Ardennes this is less suitable. Luggage transfer is not always available in winter; check the trip pages for exact periods and departure dates.

The Bookatrekking app shows the current forecast for each stage based on the coordinates of your accommodation, so the day before you know exactly what to expect and can adjust your clothing and gear accordingly.

The Ardennes have no mountain hut system like the Alps. Instead you sleep in small hotels, guesthouses and inns in the villages and towns along the route. That has a big advantage: you sleep in a real bed with a shower, breakfast is ready in the morning and you can eat in the village in the evening. The atmosphere is small-town and personal, and the accommodation is functional and comfortable.

Because the routes follow inhabited valleys, luggage transfer is straightforward to organize. On the Escapardenne Lee Trail and the Escapardenne Eislek Trail, luggage transport is included in our package: you leave your bag in the lobby and it is waiting for you when you arrive at your next overnight stop. You walk all day with a day pack of 8 to 12 liters for water, snacks, a rain jacket and your essentials. Check each trip page to see exactly which services are included, because this differs from trip to trip.

Wild camping along the route is not allowed. Accommodation in the smallest villages is limited, sometimes one or two addresses per stage, and in high season those fill up fast. Booking early is not an unnecessary precaution.

Which trip suits you? Short on vacation days, or is this your first multi-day trek? Then the Lee Trail is the logical choice: five days including arrival and departure, manageable stages and a route that gives you the feel of the Luxembourg Ardennes right away. Want a full week of walking with the maximum change of scenery, from the Luxembourg slate valley to the forests of the Belgian Ardennes? Then choose the Eislek Trail. Have the time and want the most complete traverse? Then the full Escapardenne is the answer. Want to cross the Belgian Ardennes specifically from east to west, on the longest and most varied route? Then walk the Ardennes Trail.

For maps, GPX and navigation: the routes are waymarked on the ground, and through the Bookatrekking app you have the offline map, the GPX track and the current forecast for each stage, so you always know where you are and what the day will bring.
