We are OPEN 7 days a week 10am-6pm. We operate on a first-come-first-serve basis, your Ontree Team


The courses are one-way-courses and independent from each other. Back on the ground from one course, you can decide, which course you want to climb next. You can build up the challenges step by step. During the 3 hours time slot you have the free choice of climbing any of the courses, depending on your courage and skills. We recommend a slow progression. For each course you should allow a 25 to 40 minutes climbing time. For security reasons, an adult can only accompany 2 children aged 8 – 12 years.
