About Boulder & Cave

Who we are and how a typical hire works.

+What is Boulder & Cave?

We're a UK-based mobile adventure company. We bring two flagship experiences to your venue: a trailer-mounted bouldering wall and a portable artificial caving system with over 90 feet of two-level tunnels. Both come fully staffed, fully insured and ready to run.

+Where do you operate?

We cover the whole of mainland UK. We're based in the South West but regularly travel nationwide for schools, festivals, corporate events and family days. Travel beyond a certain radius may include a small mileage contribution — we'll quote that up front.

+What kind of events do you do?

Schools, summer fetes, festivals, corporate family days, team-building events, scouts and guides, birthday parties, council events, military family days and brand activations. If you've got a flat patch of ground and a crowd to entertain, we can usually make it work.

+Are you insured?

Yes. We carry £5 million public liability insurance and all of our equipment is independently inspected and certified. Risk assessments and method statements are provided on request — useful if your venue or local authority asks for them.

+Are your instructors qualified?

Every session is run by our own in-house trained, vetted instructors. Our climbing staff hold recognised climbing instructor qualifications and our caving supervisors are trained in confined-space supervision, first aid and safeguarding. All staff are DBS-checked.

Mobile bouldering wall

Climbing-specific questions about the wall.

+Is a mobile bouldering wall the same as a mobile climbing wall?

It's a type of mobile climbing wall. Bouldering means low-level climbing without ropes or harnesses, so climbers traverse around the wall rather than climbing high above the ground. That makes mobile bouldering wall hire quick to run at busy events — no harness fitting, no queues while one climber is roped in.

+How much space does the bouldering wall need?

Around 10m × 6m of flat, stable ground is ideal. Grass, tarmac and indoor sports hall floors all work fine. We also need vehicle access to drop the trailer into place.

+What's the minimum age for the climbing wall?

We welcome climbers from age 5 upwards with no upper age limit. Routes are reset to suit the group — gentle traverses for younger kids, trickier problems for teens and adults.

+Do climbers need any experience or special kit?

No experience needed. Just wear trainers and clothes you can move in. We provide everything else, including the safety briefing and instructor supervision.

+Is it safe? What happens if someone falls?

Bouldering is climbing without ropes at low heights, so falls are part of the activity. Crash matting surrounds the wall on all sides and instructors spot every climber. We brief everyone before they get on the wall.

+How many people can climb per hour?

Up to around 30 climbers per hour, depending on the age and confidence of the group. For school days or fetes we'll talk through the schedule with you to keep queues moving.

+Do you run indoors as well as outdoors?

Yes — provided the indoor space has enough floor area, ceiling clearance and vehicle access for the trailer. Sports halls and large marquees usually work well.

Mobile caving experience

Everything you need to know about the cave system.

+What is the Trailer Cave?

The Trailer Cave is the name of our mobile caving system — a trailer-mounted artificial cave with over 90 feet of two-level tunnels. People also search for it as a mobile caving experience or portable cave system; it's all the same activity.

+What's actually inside the cave?

Over 90 feet of tunnels across two levels, complete with sump ball pits, stalactites and stalagmites, tight twists and proper squeezes. It's the most realistic artificial caving experience you'll find above ground in the UK.

+Is the caving experience suitable for young children?

We recommend ages 5 and up. The interior is dark and the tunnels include tight sections, so it's not suitable for under-5s. Minimum user height is 1.1m.

+What if someone is claustrophobic?

The cave is a confined, dark space, so it isn't suitable for anyone with claustrophobia. We also ask people with severe heart conditions or epilepsy not to enter. If you're unsure, get in touch and we'll talk it through.

+How big a person can fit through the cave?

The tunnel system was modelled around an adult caver and fits a person up to roughly 6'4" tall, with a 44" chest, 20" shoulders and 42" waist.

+How many people can be in the cave at once?

Up to 10 explorers inside at any time, with two of our trained staff supervising entry, exit and progress through the system.

+How much space does the caving trailer need?

The operational footprint is 10m × 6m to fit both the trailer and the gazebo entrance. The trailer itself is 8m × 2m. The ground needs to be flat and stable; no power supply is required.

+Can we brand the trailer for our event?

Yes. Both the trailer and the gazebo can carry your logos or event graphics — popular for sponsor activations, town-centre takeovers and branded family days.

Booking, pricing & logistics

How to book, what it costs and what happens on the day.

+How do I get a quote?

Head to our contact page and tell us what you're after — date, location, expected numbers and which experience you'd like. We'll come back with a tailored quote, usually within one working day.

+How much does it cost to hire?

Pricing depends on location, duration, number of activities and whether it's a weekday or weekend. As a rough guide, a single activity for a half-day starts in the low four figures. We'll always give you a clear, all-in quote with no surprises.

+How far in advance should I book?

Peak dates (summer weekends, school events in June/July, December festive bookings) often go six to twelve months ahead. For everything else, four to eight weeks' notice is usually fine. Last-minute bookings are sometimes possible — just ask.

+Do you need a deposit?

Yes — a deposit secures your date, with the balance due closer to the event. Full terms come with your quote.

+What happens if it rains?

Both setups are weather-resistant and we run in light rain. For heavy rain, high winds or extreme heat we'll talk through options — relocating indoors, adjusting the schedule, or rescheduling. We don't cancel lightly.

+How long does setup and pack-down take?

We arrive 60–90 minutes before your start time to set up. Pack-down is typically under an hour after the last session.

+Do you need power or water on site?

No. Both experiences are fully self-contained — no mains power or water required.

Still got questions?

We're a small team and we answer enquiries personally — usually within one working day.
