By public transportation:
Spa has a regular connection with Verviers, which lies on the line Ostend – Cologne. The train station of Spa is 650m away from the house. On the contact page, you can find a map with both the train station and Le Jardin d’Henriette.
If you’re coming from Flanders, you’ll have to go through Liège, where you go in the direction of Verviers. You’ll end up on the E42. Leave this at exit 8 – Spa. You can avoid the city centre of Spa by taking the first exit at the second roundabout, along the Radisson Balmoral Hotel. After this, take right at the next roundabout (you’ll see the thermal baths right in front of you) en at the following roundabout left. At the end of the descent, take right to Promenades des Français. You’ll find the house after ca. 100m on the right side of the street.
Please note when parking your car that the road into the forest must stay accessible for emergency services.
It is possible that your GPS will lead you to the other side of Promenade des Français. This is annoying, because Promenade des Français is fenced off by a barrier on both sides. If this happens, follow Avenue Reine Astrid towards the city centre and take left at Match. After ca. 100m you’ll find Promenade des Français right in front of you.
