Totally worth the walk there, specially if you get Kitty (the grumpy, red hair lady) as your guide. Very interesting facts about the underground tunnels and Maastricht's history as well . Loved it! :)
Wear something warm for the guided tour ! Like, 3 sweaters, a coat, scarf , mittens, and a hat. Maybe some warm boots . God someone get me a blanket
Buy combiticket with the Fort and wear something warm. Great experience, must visit!
Nice restaurant , but take a warm jacket for the guided tour ..

Très belle découverte par une journée pluvieuse. Le guide que nous avons eu et qui parle aussi anglais a su nous transporter dans le passé. 11° à l’intérieur toute l’année. - Richard Moerland
Bitterballen are great! Heavenly combined with Coca Cola. - Lauren Hannah
One of the few dutch hills, it worth the visit. Don't forget the caves - Flávia Regina Bueno
