Harry Potter party at The Medieval Barn | Brecon Beacons

Sleeps 10 + 2 dogs (option to rent further properties on-site for up to 30 guests)

The Medieval Barn

Grab your spellbooks and wands, and magically transform The Medieval Barn into Hogwarts for the ultimate Harry Potter party. The wizarding world is still very much a popular kids' birthday party theme, and this striking period property offers the perfect setting to conjure a soiree that no wizard, witch nor muggle will ever forget.

The enormous double-height dining room with a solid oak table that seats up to 30 guests will become The Great Hall, which you can adorn with potion bottles, chocolate frogs and coloured placemats or tablecloths for the different Hogwarts houses. Enjoy a celebratory feast before hosting a Sorting Ceremony, a fun Transfiguration or Potions Class, or even some Wizard’s Chess. And there is an atmospheric lounge with a wood burner that you can easily transform into your very own Three Broomsticks or Honeydukes, serving some delicious, frothy Butterbeer.

Pirate party at Trenarren | Cornwall

Sleeps 10 + 2 dogs


Set sail into the perilous seas and get ready for a swashbuckling good time with a pirate party at Trenarren in Cornwall. With breathtaking sea views, private access onto the soft, golden sands of Perranporth Beach, and a large, terraced garden with a sunken hot tub, this party pad is an incredible venue for one of the best birthday themes for boys.

Shiver the timbers of the pint-sized pirates you have onboard by handing out treasure maps and sending the wee scallywags on a thrilling treasure hunt on the beach. An outdoor shower offers a handy spot to wash off sandy little feet when they return, before letting them walk the plank to a buffet of treats fit for any captain. Why not try cannonball meatballs, hot dog ships, or vegetable swords?

Enchanting forest party at Fairsnape | Lake District

Sleeps 12 + 1 dog


Lead the kids on a captivating woodland adventure with this unique children's party theme at Fairsnape in the Lake District. Set within 4 acres of enclosed woodland gardens, the owners have created a magical seating area around a large fire pit, offering an idyllic spot for a wild birthday bash to remember.

There are so many woodland party games you could enjoy here, from fairy hunts to woodland crafts and den building competitions. Encourage the kids to look for minibeasts under logs and stones, craft a natural obstacle course using found objects and gather everyone around the campfire for songs, stories and hot chocolate. Fruits, berries, seeds and trail mixes are great snack ideas for a party set in nature, as well as chocolate acorns, ants on a log and pretzel sticks labelled as twigs. And if the grown-ups need a little rest and relaxation after the festivities, there’s a luxurious hot tub to retreat to.

Mermaid party at Oakfield | Somerset

Sleeps 16 + 2 dogs


If you’re looking for birthday party themes for girls, it doesn’t get much more glam than a mermaid party at Oakfield in Somerset. Nestled within 7 acres of gardens, its outdoor heated swimming pool sets the spellbinding scene for an underwater paradise. Throw in the inflatables and while the mini mermaids make a splash and play pool games like musical floats, relay races and underwater treasure hunts, the adults can get the poolside BBQ sizzling.

A pool house makes a great spot to lay out finger food and the all-important birthday cake – why not opt for an iridescent mermaid tail cake with a shimmering iced fish scale design? There’s also a pizza oven, fire pit, hot tub, climbing frame and table tennis table, so you’ll be spoilt for choice with the amount of entertainment on offer here.

Playing cards, pink flamingos, pocket watches and an assortment of colourful crockery will complement the theme, and guests can come dressed as iconic characters, like Alice, the Queen of Hearts, Tweedle Dum and Tweedle Dee. A trampoline, swingball set and BBQ add further entertainment, and the breathtaking views of the Brecon Beacons are sure to leave all ages grinning like Cheshire Cats.
