About Funny Mountain
Funny Mountain is an indoor climbing centre at Rue de Grass 101 in Arlon, on the Belgian side of the border twenty minutes from Luxembourg City, next door to LUXFLY Indoor Skydive. The birthday runs in three tiers: SMALL (one hour of supervised climbing plus a 30-minute birthday space with BYO cake); MEDIUM (climbing plus a decorated private room and a cake); VIP (privatises the climbing room itself, for class-sized groups). All tiers run from age 5 upwards.
Best for
- Active kids aged 5 and up ready for a real supervised climbing wall.
- Class-sized groups where parents want the climbing room privatised, not shared.
- Drop-off birthdays where adults welcome the no-spotting-required setup (above age 10).
Good to know
- SMALL now includes a 30-min birthday space with BYO cake and drinks (no fridge provided); MEDIUM and VIP include a private room and a cake.
- Adults must accompany under-10s on the wall (roughly one adult per four to five kids).
- Cross-border venue in Belgium, A4 exit Arlon.
- VIP requires a 15-kid minimum to unlock the privatisation rate.
