The highlights: 

  • Outdoor bar – cask and kegged lagers can be arranged with the owner
  • Pool table 
  • Private indoor swimming pool

What our guests say:

Fantastic home. The host was very helpful and accommodating. Wonderful location. We were here on a stag holiday and I think it would be suitable for any large group of friends/family. Lots of good walking in the area. Would highly recommend.– Daniel

Southwood Chase

A water sports party at The Summer Lake Retreat | South Cerney, Cotswolds

Sleeps 8

Take a few of your closest friends to this beautiful lakeside holiday retreat for a party out on the water. With its wonderful location in the Cotswold Water Park, a rather exclusive part of the UK, there’s ample opportunity for water sports with the group. Experience kayaking on the Cotswolds lakes, enjoy swimming or go sailing. Wakeboarding, water-skiing and windsurfing are all perfect activities for an active party weekend.

The highlights:

  • Scenic waterside views as it sits in the centre of Cotswold Water Park
  • Private mooring
  • Shared tennis court.

What our guests say:

‘Me and some friends stayed at Southwood Chase for a much needed getaway and we couldnt fault the experience at all. The pool was perfect for us and the outdoor bar was a great addition to the property. I have to say the owner, Rob, was amazing throughout the whole week and we couldnt have asked for a better host. Definitely recommend staying here.– Harry

The Summer Lake Retreat

Surf the waves at The Old Cider Barn | Croyde, Devon

Sleeps 16

The old cider barn

Known as a top surfing spot in the UK, Croyde is the perfect destination for both frequent surfers and beginners. What better way to celebrate a 21st birthday party than by doing something you love, or by challenging yourself to learn a new skill? Swim, surf and soak up the sun, then sit back and relax for an evening BBQ by the beach watching the sunset over a few beers. There’s nothing quite like it.

The highlights:  

  • Within walking distance to the beach, shops and eateries of Croyde 
  • A separate annexe sleeps 2 for extra privacy.

What our guests say:

Such a beautiful house in the heart of Croyde! Spacious, clean and very well equipped with a very short stroll to some lovely restaurants. A short drive to beautiful sandy beaches and great location for day trips. Would highly recommend!- James

The Old Cider Barn 

A dance party at Rock-rose House | Eggleston, County Durham

Sleeps 20

An elegant country house that you may recognise as the finishing school in the hit show Ladette to Lady. Behind the ancient walls of this magnificent stately home, you’ll find a grand hallway perfect for a party. Pick your favourite music or hire a DJ and let partygoers dance the night away in the hall. You could even hire a bartender to pour drinks and create a unique cocktail for the occasion or a caterer to whip up some tasty canapes.

The highlights:

  • Tennis court and garden games
  • A billiard room with table football, table tennis and surround sound music system

What our guests say:

'We had a great time - all of us, ages 6 - 75 and everything in between. The house is a delight with so much room everywhere. The bedrooms and bathrooms were wonderful and the furnishings all through the house were impressive. The kitchen was amazing. The wi-fi was a bit intermittent but with so much to do it didn't matter greatly, although the youngsters would have appreciated it. Tennis, snooker and table tennis were much enjoyed. Thank you - we had a ball!'  – Kate

The Hall Teesdale

A spa weekend at Chy Lowen - Tresavean | Cornwall

Sleeps 10

You only turn 21 once so it’s time to pamper yourself. Indulge in a spa party at the delightful Chy Lowen – Tresavaen in Cornwall. Light the BBQ, soak in the bubbling hot tub and cocoon yourself in warmth when you step inside your own private Scandinavian sauna. When everyone’s feeling refreshed and relaxed, your group can sit together and chat in the spacious lounge or dine alfresco beneath the stars. 

The highlights:

  • A sauna and hot tub
  • A large garden with outdoor furniture 
  • Dartboard and table tennis in the garden

Chy Lowen - Tresavean

21st birthday party cake ideas:

  • Cake pops - they may be small but you could make a dramatic impact with an awesome arrangement and the party guests can snack on them throughout the night 
  • Chocolate cake -  it’s only right that you pick an indulgent cake that is rich and melts in your mouth
  • Gin and tonic drizzle cake - super easy but it's delicious and perfect for the occasion
  • Pinata cake - if you've had a day full of activities, a bit of sugary goodness may be just what your party needs.
  • A sports-themed cake – it’s a classic. Golf, football, rugby - whatever the guest of honour loves best
