Hangar 51 Nerf and Gelfire battles

A 1.5 hour exclusive battle experience inside Hangar 51 — Mendip's immersive indoor Nerf and Gelfire combat arena.

What is Hangar 51?

Hangar 51 is a decommissioned military hangar once used for classified extraterrestrial research — now reactivated as a high-energy indoor battle arena where you become the hero in your own real-life action game.

Packed with bunkers, glowing ammunition, fog effects and immersive lighting, Hangar 51 turns a simple blaster game into a full tactical mission.

It is the perfect experience for birthday parties, celebrations or groups of friends looking for something exciting and different.

Nerf Blasters

FAQ's

Gelfire is a safe but fun way to bring battle games to life. It's similar to paintball but without the pain or mess and can be played indoors. With automatic and semi-auto fire your Scouts will love the all new experience of Gelfire. The hydrated UV ammo glows in the dark and looks just like live-tracer fire. The gels leave no stains or marks and doesn't hurt. 


You can feel when you have been hit but it doesn't hurt. It's just like being hit by a Nerf foam dart or elastic band. Safety goggles are provided and mandatory at all times for everyone in the battle zone.

Tobogganing

Tobogganing is a very popular activity and, especially during peak times, we have very little flexibility in being able to push your start time back. Where possible, we will get you onto the toboggan slope as soon as possible once you arrive. We will try to be as accommodating as possible and if there is availability later in the day, we will move your session to a later start time however please be aware that this is not always possible. 


Frisbee golf or recreational snowsports

We are likely to be able to change your start time at arrival as long as it is within our opening hours and on the same day.


Private Activity Session
We will start whenever you arrive but we are unlikely to be able to overrun.


Individual Spaces on an Activity Session

We will do our best to fit you into the session at a point that does not disrupt it too much for other participants. If you are more than 10 minutes late, we're sorry but it is very unlikely we will be able to fit you into the session due to missing the safety and equipment briefing and kit up.
