Testimonials - Parties

  • Just to let you know that the children had a great time on Saturday! They are all talking about it and very enthusiastic with rock climbing!

  • The Geckos climbing party for Annie was a great success - the girls had a super time and all felt a great sense of achievement. The instructors did a sterling job of trying to teach them and keep control when they were so excited. Many thanks for this.

  • Thank you very much for a successful party. It went down really well and the birthday boy and his Dad are now hooked. They are talking about doing it seriously now on a regular basis.

  • Richard and Kat at Geckos climbing gave my 10 year old daughter one of the best birthday parties she’s ever had. All the children had a fantastic time, having fun while challenging themselves mentally and physically and learning new skills. The tuition was expert, professional, reassuring, and confident - all done intelligently and with great expertise with the children. The experience of climbing to the top of some very high walls was unforgettable and even those who didn’t think they could do it, found themselves achieving things way beyond their dreams. I would thoroughly recommend this as a way to celebrate your child’s birthday.

  • Just wanted to say thank you for last Saturday, our daughter and all her friends really enjoyed the climbing party. The two instructors were excellent, very reassuring to the more nervous/inexperienced children and good at spotting who needed closer supervision.

  • Just wanted to thank you again for Saturday, Sam and his friends had a great time. Sam and James had such a good time they want to come to the 3 day course first week in the Easter holidays.

  • Just a quick note to say a huge ‘thank you’ to you and your outfit- in particular our two instructors. They had a really great way with my daughter and her five friends who absolutely loved their session on Saturday. Watched the video of it when we got home which had them all squealing, reliving their slab moments. Terrific fun and v well organised. The kids are all now hooked on climbing...

  • I just wanted to thank you for the birthday party you did for our son, Alexander, on Saturday. The boys (and my daughter!) thoroughly enjoyed themselves. My husband and I were impressed by the level of professionalism and enthusiasm you had with all of the children. You encouraged them to push themselves in a safe, challenging environment. It was a day they will all remember. The only problem we have is that my son is completely “hooked” now and can’t wait to go again! Thanks again for a great day. I will definitely recommend you for future reference.

  • Our group of ten nine year olds had a fantastic time. Great mix of scary-but-exciting and encouragement and support which meant they are all buzzing about it five days later. The instructors were absolutely brilliant with the kids. We chilled out in the cafe and then had a picnic in the lovely gardens afterwards. All in all, I have been told that this was the “best party ever”. We’ll be back next year if not before...

  • My daughter and her friends had an amazing time at the Geckos climbing party to celebrate her birthday. Lucy, the instructor was excellent and I cannot believe how many walls she managed to cram into the session! Grace has already said she would like another climbing party next year! Thank you for a party different to the norm.

  • A belated thank you for a wonderful birthday party for Sophie. She, her friends, and her little brother all had a fantastic time, and are all talking about when they can do it again! Thanks again, and please thank the instructor again for us – she was very calm and encouraging and all the children achieved new heights!!

  • Bella had a great 9th birthday party with her friends. I can’t thank the instructor Richard enough for making her day so enjoyable.

  • Thank you so much for Jazzi’s fantastic climbing party at the Castle! Everybody absolutely loved it. Great how you got them all involved and kept it fun and interesting for every single girl, ranging from the not very agile to squad gymnasts with previous climbing experience! Finally, I was very impressed indeed how well you managed to keep our crazy bunch of hectic 9 year olds under control without a single one of them perceiving you as strict in any way. Awesome birthday party. Miles ahead of those climbing parties often offered in leisure centres with climbing walls. We will warmly recommend you!

  • Just a quick note to thank you very much for Izzie‘s party/climbing session last week. She and her friends had a great time. We were very impressed by the instruction you offered them and by the amount they achieved in the session.

  • Please could you say a huge ‘thank you’ to the instructor Sophie on our behalf. She did a fantastic job of Mikey’s birthday party on Saturday, with just the right blend of fun and challenge, and all the boys seemed to enjoy themselves enormously. It was brilliant!

  • Thank you for a really good climbing party on Saturday. Joh was a great instructor and very kind to the kids. Conrad and his friends had a great time and Conrad’s only complaint is that the time went too fast! As he really enjoyed it, we are thinking about signing him up for the climbing club.

  • We just wanted to say thank you for a brilliant Geckos climbing party. My son (11) and his friends had the most fun bouldering and top-roping all round the Castle. (It was “totally sick”, apparently!) Rich and Julie, the instructors, hit exactly the right combination of friendly banter and wise instructions, and very cleverly managed to make it equally enjoyable and challenging for those who had climbed before and those who hadn’t. Best of all, we got to sit in the café and watch them all having a blast, safe in the knowledge that we’d be collecting a band of happily exhausted boys at the end. Result!

  • Our son had a fabulous ninth birthday party with Geckos. The group of twelve, both boys and girls, enjoyed themselves enormously and even those who were nervous at first all ended up climbing impressively. This was definitely our son’s most rewarding birthday party yet.

  • Thanks for giving Becky and her friends your expert tuition and encouragement. They all really enjoyed it and said they would do it again.
