The Most Adventurous Stag Do Activity in Belfast
Last updated on December 3rd, 2025 at 11:18 am
Any proper Belfast stag do has to tick a few essentials off the list — a few pints, a good feed, and a plan for the morning after when only a fry in a Belfast bap will save you.
But if you’re the one who’s been handed the job of planning the stag activities, and you’re sick of sweating in a jumpsuit while go-karting, can’t stand another afternoon shivering on a beer bike, or can’t be bothered with post-paintball bruises, Prison Island Belfast | Multi-Activity Venue has more than a few tricks up our sleeve.
Ever had a stag where the groom ends up behind bars? Now’s your chance. (Don’t worry — nobody’s actually locked in.)
Stress-Free Planning For Any Stag Do
Will the best man in charge of the stag do budget please stand up? We know that juggling prices about and getting everyone sorted to pay can be a headache when loads of activities have different prices. At Prison Island, we keep it simple so you can focus on the craic, not the chaos.
Why we’re one of Belfast’s Top-Rated Stag Do Activities
4 Activities – 1 Roof. Prison Island is all about giving groups the best time possible. We find that stag dos have more craic when they double up on activities, opting for something that matches their group vibe, which is why we offer the following for a one-of-a-kind experience:
- Prison Island – The OG
There’s a reason we are consistently featured among TripAdvisor’s top activities in NI. We’re bringing new energy to what we call “an Escape Room…but Better!”.
You venture into the prison in groups, taking on challenges behind locked doors (one team at a time), competing to get the most points. Think of it like The Crystal Maze taken up about 10 levels in terms of gameplay and fun.
Our Stag Do Extra Time Package is the most popular — an hour and a half inside the Prison, giving the lads plenty of time to rack up points, get competitive, and settle a few scores.
We also offer the 1-hour option: short, sharp, and intense — perfect if you’re squeezing a lot into the day.
One of the funniest parts of any stag booking at Prison Island Belfast is The Wheel of Privilege.
Every stag gets one chance to spin the wheel and claim a FREE prize — and it can go very well… or absolutely terribly.
You might land on:
• Alcohol drinks for the stag after the session
• A bonus prize for the whole group
• Vouchers to return
• Or a booby prize that the lads will not let him forget
- Axe Yard – Real Axes. Really Good Craic
Axe throwing at stag dos is really common. If you’ve ever done it in a space where you know the target board has seen better days, you’ve not experienced it like Axe Yard does it. We got bored of looking at the same old axes and boring targets & decided to completely upgrade it, creating a fully interactive axe-throwing experience upstairs. It has digital games you throw real axes at & 0% drink offers available.
18+ only, and closed-toe shoes required — no alcohol to be consumed before throwing, but there’s plenty of time after!
- Quiz Boxing – Delivering a Knowledgeable KO
Are there a few in the group who live for game shows, shout answers at the telly, or secretly reckon they’d clean up on The Chase?
See how they cope when they’re face-to-face in our Quiz Boxing arena.
With pro-level lighting, dramatic music, podiums, buzzers, and quizzes ranging from our pre-loaded rounds to the highly embarrassing questions you can submit, we drop you straight into a full TV-show setup — only this time you’re competing against your own mates.
If you’re adding Quiz Boxing, you’ll also get a FREE personalised round built around the groom and the group. Ideal for a bit of slagging… Perfect for winding him up without going overboard.
It’s unique, ridiculously competitive, and guaranteed to be one of the biggest laughs of the weekend.
Plus, you get to leave saying you quizzed in a cage.
- ThinkBox: The Ultimate Mind-Bending Challenge
Best suited for stag dos that love a Wordle, know what the symbols on Only Connect are, and know they’d boss an escape room in record time, ThinkBox has 12 distinct boxes, each housing a labyrinth of 80 locks. It’s a unique puzzle challenge where teams race against time to collect tokens and earn points. Learn more about booking in for ThinkBox here.
You can bundle all the activities you want together. When you book your first, you’ll be given the option to have additional stag do activities as part of a bigger session, like this:

What Your Prison Island Visit Looks Like
You’ll be in and ready to go in no time. At reception, we’ll brief the group, split everyone into teams of 2–4, and fire off a few mugshot photos for the craic. Each team gets tagged, and any contraband goes straight into the free lockers provided. If you’re flying in and hitting Prison Island Belfast before checking into your accommodation, there’s plenty of space to leave bags safely in the locker area.
Once you’re inside the prison, you can dive into the 31 challenge cells in any order you like. The goal? Rack up as many points as possible before your sentence is up. A real-time live leaderboard shows every team’s score — complete with your chosen team names — so you’ll know exactly who you need to beat.And as the clock ticks down and the points climb, trust us… the competitiveness ramps up fast. You’ll be doing everything you can to walk out as the winners. Lots of stags will book activities back-to-back (more on that below), but to get started, just click right here. Pick a date and you’ll see the packages. If you need any help, give us a quick call on 02890 380862.
