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 SUP or rock-climbing. We’ll put the perfect stag do together, tailor-made to suit your group, taking all the stess out of planning!

Hosted Stag Adventures

With any of our Big Blue adventures we always aim for a personal customer service (Travel & Hospitality Award winners for ‘excellence in customer service 2017’) and have a friendly face there to welcome you to your stag do in Wales. We are on hand to host the key parts so you can sit back and relax, we’ll do the organising for you and bring some good vibes too!


If you need transport from your accommodation to our activities then we can arrange that for you, in fact it is usually expected on a group trip like a stag do. We have mini-busses available for groups of all sizes. Our mini-busses are also available for night out returns and various day-trips to surrounding areas. A popular option is a morning activity followed by lunch and some drinks at a local pub before heading back to the stag accommodation!

Pictures & Highlights Video

On a hosted adventure we take our GoPro cameras and shoot some cool pictures & videos. We’ll send these to you afterwards and make a personal highlights video for your group, the best way to remember your trip! If you’ve booked the activity only and we are not there, let us know if you’d like any pictures, we can always arrange something.

Meals & Drinks

You can choose between Bed & Breakfast, half board or all-inclusive for your stag party. We can also add extras like a drinks-reception package, packed-lunch and BBQ’s. Just add it to your ‘get quote’ options and we will get that included in your stag package!

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

Booked a Canyoning Day in the Brecon Beacons for the 10th of May for a friends Stag do. From the... first email sent - Dan gave the best Customer Service I've ever experienced.

The day was a lot of fun - Dan took care of every little detail, ensuring it was a memorable day for all and genuinely cared that we all had a great time.

Could not recommend Big Blue Adventures enough and hope another event comes along that means we'd book again!

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.”
