Welcome to Tree Cross Adventure in Atsugi/Nanasawa.

Tree Cross Adventure is covering 25,000 square meters in a hilly terrain. We have designed 6 thrilling adventure courses, which among others are featuring a 173 meter long zip line, crossing a 30 meter deep valley and course activities as high as 10 to 15 meter up in the trees. This is an ideal park for a family outing, fun time with your friends or corporate training like team building. English speaking instructors are available.

We are less than an hour drive away from Tokyo. Get on at the Tomei Yoga IC and exit at Atsugi IC. From here you head towards the Nanasawa onsen resort, which is our immediate neighbour. After a fun workout in our park there is no better way than to finish the day with a dip in the hot springs.

At Tree Cross Adventure, our first rule is, that you are responsible for your safety while you do the course. In the trees you will be in control of your own safety equipment, making sure you are properly attached as you move around the course. We use a so called self belay system, which is one of our most attractive features, as it puts you in charge, and it means the experience is serious as well as fun.

Our park is built in compliance with European safety standards as Japan lacks safety regulations for this type of activities.

Course activities as high as 10 to 15m up in the trees
