21st Birthday Gifts & Ideas

Make the big 2-1 a day to remember! A unique experience from Red Letter Days is the perfect 21st birthday gift, creating long-lasting memories for years to come.

Seasoned adventurers, part-time petrolheads or lovers of all things pampering are sure to be delighted.

Celebratory Adventure Experiences

There are plenty of thrilling pursuits to commemorate this special occasion. Push the boat out with a watersports session, perfect for the summer. White water rafting puts teamwork to the test as explorers tackle flowing rapids. Beating a challenging course is super rewarding! For something with a gentler pace, kayaking experiences offer a calm tour of the UK’s coastal regions. Or send them skydiving for something they’ll never forget. After taking in the safety briefing and climbing to a breath-taking height, it’s time to jump! Freefalling through the air is unlike anything else.

Exhilarating Driving Days

Are they an aspiring racer? If so, they’ll cherish time spent burning rubber on purpose-built circuits. Get them behind the wheel of their dream supercar as they put it through its paces on the tarmac, including Lamborghinis and Aston Martins. From thrill rides in one car to trying out an array of luxury models, there’s something for lovers of every brand. Or let them follow in the tyre marks of world-famous F1 drivers, like Lewis Hamilton, at a real racing track! Hosted at famous venues across the country, aspiring racers take on the straights, bends and cambers of the track in an attempt to get the quickest lap possible.

Birthday Pampering

Mark their 21st with pure luxury. Get them a session in a spa for a chance to unwind and recharge. Massages soothe the muscles, facials rebalance natural oils and exfoliate the skin and mani-pedis add some extra style. After enjoying a relaxing treatment, make the most of the resort’s calming amenities.

Terrific gift.

Excellent, we really enjoyed the Six Course Gourmet Meal with a Cocktail for Two at Marco Pierre White London Steakhouse Co. The food was superb, the atmosphere great and considering the restaurant was packed the service was excellent and attentive.

14 strangers around a round table

We met in the bar as 14 strangers and left as friends all laughing about the experience. Its a very slick and well organised experience based on the TV show Traitors. Highly recommended if you enjoy the show....however the train journey home was awkward after my partner voted me off and banished me as a Traitor

Great experience with great staff

Superb experience and a great time had, plenty of free samples on the tour, make sure you tell them you are driving so the samples you get are smaller but in return they will give you some to sample at home as well. Team were very knowledgeable and happy to keep the drinks flowing as they give you the tour.
