Tripadvisor rating

Plan an unforgettable adventure stag do in Cardiff and the Brecon Beacons including accommodation

Why have your big stag weekend in Cardiff, Wales’ exciting capital city? Having a stag do in Cardiff combines one of the best cities for a night out in the UK with outdoor activities in the Brecon Beacons, a stunning mountain range nearby! This gives you the best of both worlds and it makes our Cardiff & Brecon Beacon stag weekend packages very popular amongst our other Wales stag do’s!
Cardiff is a fantastic city for stag parties, but if you want to get away from all the city carnage, how about spending the entire weekend in the Brecon Beacons for that complete outdoorsy stag weekend experience!

Big Blue offers stag friendly quality accommodation like private villas, hotels & bunkhouses, with a range of outdoor activities like paddleboarding or rock-climbing. We’ll put the perfect stag do together, tailor-made to suit your group, taking all the stress out of planning! When you’re ready just hit the Quote button, call or email us direct.

A popular option is a morning activity followed by lunch and some drinks at a local pub before heading back to the stag accommodation!

I can't recommend these guys enough. I was planning a stag do through Dan during Covid and he was... absolutely brilliant at keeping me informed of any alterations/alternatives and in fact the weekend was even better than what we originally planned. Well done Dan and thank you, top organising! The accommodation, The Citrus Hotel in Cardiff was ideal, clean and great location. Bus was on time to collect us. Dan and Heleen were there to welcome us and were amazing throughout the day. Paintballing was brilliant fun, as was the canyoning and the packed lunch was great. Can't wait to see the GoPro footage from the day! They use well organised professional activity instructors/companies. Looking forward to my next weekend away with these guys! Thank you for everything, you were both patient and brilliant. Good luck with the expansion!read more

Big Blue staged my brother's stag based in Brecon but with a night out in Cardiff. The experience... was brilliant. As best man, I did the liaison with Dan who listened carefully to the brief and came up with an awesome schedule. Accommodation in Brecon was really superb and provisions were there on arrival so we didn't have to even think about food before rolling down to the local pub for some beers after arrival. Saturday's logistics in and back out of the city at the end of the night were flawless (we went to watch Wales vs. Barbarians). Finally, a great time canyoning on Sunday - definitely exciting enough to make us forget about early December water temperatures! We received enough kit including balaclavas/booties, etc to stop us shivering. I'd thoroughly recommend Big Blue to anyone after the time we had. A big five stars from me, the groom and his fellow stag attendees!read more

Had a great experience when booking a stag activity in Cardiff with Dan and Heleen, they could not... have been more welcoming or helpful and were very accommodating and communicative right from the booking process through to collecting us from our hostel and making sure we all enjoyed a great afternoon of canyoning in the Brecon Beacons. Our group had a lot of people who were totally new to this type of activity and it wasn't a problem thanks to the help of the team on the day. Absolutely no hesitation in booking again soon for some of their other packages, thanks guys from everyone at Stephens stag do!read more

Why We Love This…

“A Cardiff or Brecon Beacons stag weekend is awesome because there are so many cool places to visit close to the city. Canyoning is definitely our most popular stag activity. It’s a real adrenaline hit with fun slides, big jumps and huge waterfalls.. it just never gets boring! If you don’t have a full day to do activities, white water rafting in Cardiff Bay is another great option.”
