Belgium is a wonderful place to visit, with plenty of quieter places, away from crowds, to explore. Perhaps one of its most beautiful natural spaces is the Sonian Forest, an ancient gathering of trees, some of which are more than 200 year’s old.
UNESCO protects three large regions of the forest for wildlife conservation, so this is a great place to spot deer, boars, foxes, and more. Or, simply wander the many paths through the trees and soak up a little peace and quiet.
Where is the Sonian Forest?
The Sonian Forest lies to the southeast of Brussels. It stretches over three Belgian regions; Flanders, the Brussels-Capital Region, and Wallonia.

The picturesque Sonian Forest
Driving to the Sonian Forest from Calais
Driving from Calais to the Sonian Forest will take around 2 hours and 30 minutes, so you can plan some stops if you wish, you drive past the cities of Bruges and Ghent before the route arcs around the city of Brussels and to the forest itself.
Of course, because it is such a large area, there are numerous entrance points, but if you are going by car look for parking at Red Cloister in the Brussels municipality of Auderghem, and the Hippodrome in the Watermael-Boitsfort municipality.
If you are staying in Brussels, a drive to the Sonian Forest only takes around 28 minutes.
Getting around the forest
The Sonian Forest has over 5,000 hectares to explore and a variety of ways to do so. Each will give you a unique view of your beautiful surroundings.
On foot
Pack your good walking shoes as you have plenty of ground to cover. There are marked trails with various difficulty levels, some are hillier than others so make sure you go prepared.
By bicycle
You will cover more of the forest this way than on foot, especially handy if you want to visit points of interest in far apart sections of the wood. There are several Villo stations (self-service bike rentals) near the Ter Kameren Park on the edge of the city of Brussels and the Sonian Forest itself, most notably Villo Ceres and Villo Legrand. Of course, you can also bring your own bike.
Horse riding
There are designated equestrian trails and bridleways through the forest. You can also try Lord Newcastle Stables just outside Brussels for a riding school and beginners trails, which are often led in parts of the Sonian Forest as it’s so close by.

Spot wildlife like the Siberian chipmunk
Things to see and do in and around the Sonian Forest
As well as enjoying the flora and fauna, there are some points of interest and activities in the forest for all ages and abilities.
Visit the Ernest Solvay Monument
Ernest Solvay was an inventor and important political figure who lived in Brussels/Woluwe. The monument consists of a marble statue of a pensive Solvay on a granite pedestal. It’s free to visit.
Ter Kameren Gate and park
We mentioned Ter Kameren is a great place to hire a bike for riding through the forest, but it’s also well worth stopping to enjoy the park too. Right on the edge of the woodland, this urban park has a small lake with an island in the centre, called Robinson's Island. There are places to eat and relax as well as plenty of flora and fauna to relax among.
Forester's monument
This ancient Neolithic monument, dating back to the times of the Druids, is a memorial to Belgian forestry workers who died during the First World War. It was designed by artist Richard Viandier, who was inspired by the burial rites of the Celts. Each stone has the name of a forester inscribed on it. It’s a poignant site, made all the more special by the surrounding forest.
Visit the archaeological reserve at Boitfort Lakes
One of two archaeological reserves in the forest, this is the largest at 90,000 square metres. It dates back over 6,000 years but was only discovered in 1888 when local children discovered spear and arrow points. After numerous excavations finds included flint artefacts, knife points, pottery, and many other relics that point towards a Neolithic civilisation.
The Englishmen’s Lawn
A marvellous piece of history, in 1815, on the eve of the Battle of Waterloo, English soldiers played a cricket match in this area. The British Ambassador in Belgium planted an oak tree on the lawn and unveiled a bronze plaque to commemorate the 150th anniversary of this historical event in 1965. Today it’s free to visit to anyone exploring the forest.
The Red Monastery
This Augustinian priory, founded in 1367, sits on the edge of the forest surrounded by lakes through which the stream passes. It was used for hunting in the 16th and 17th centuries but today holds an art centre celebrating and supporting Belgian artists.
Jean Massaert botanical gardens
Founded by Belgian botanist Jean Massart in 1922, the garden cultivates over 2,000 different plants in a variety of wild and domesticated species, ranging from flowers such as magnolia up to complete orchards of apple, pear, plum, peach, and cherry trees. Admission is free year-round.
