What is Just-Jump Marnaz
Just-Jump Marnaz is an indoor trampoline park in Marnaz, in the Arve valley, 5 minutes from Cluses and 30 minutes from Chamonix. The park rolls out several hundred square metres of connected trampoline lanes, wall-mounted angled trampolines, a free-jump foam pit, a dodge ball arena, a slack-line and a dedicated low-trampoline area for the youngest. Timed 1-hour sessions, safety briefing before each entry, constant team supervision.
Who is it for? The activity is aimed at children from 4-6 years (dedicated zone), teens, families and groups (birthdays, stag/hen, seminars, schools outside school hours). Wide choice of packages: single session, multi-session passes, birthday deals with private room for cake and drinks. The ultimate bad-weather indoor activity in the valley, complementing the Grand Massif and Mont-Blanc resorts. Just-Jump non-slip socks are mandatory (sold on site, reusable).
