Bouldergym Sendmast is a new bouldergym 10 minutes by bike away from the city center of Alkmaar (plenty of free carpark spaces available). We have more than 120 boulders ranging from 2a-7c (beginner-advanced). We have everything you need (rental shoes, free instruction) for a nice bouldersession. And after you've enjoyed all this, a nice cold beer or cappuccino awaits you in our bar.
