Beautiful place just to park up at night and watch the stars- no booking required for that. If you want a tour though you do need to book and it's on our bucket list now!

A fantastic way to spend an evening. The only thing that wasn't great was my lack of preparation for just how cold it can get. Thankfully, the two guys who run it have blankets, hot drinks and brilliant conversations to compensate (including the expected space related to Tolkien's unexpected history of creating the Elvish language). It was a clear night for us, so we didn't have an issue, but I think it's a credit to the individual's character that they allow you to return for free if it's overcast and nothing can be seen. My only suggestions for how to improve it would be 1) When using the white telescopes, put a chair next to each telescope rather than waiting for people to ask 2) At the start of the introductory lecture, try to get a feel for the audience's subject knowledge and tailor it to help those with less remain interested. These are minor points, however. I would recommend visiting this place to everyone. I'll definitely be returning in the summer/autumn (when it isn't as chilly).

Such an interesting and informative evening! Even though the sky was cloudy so we couldn't see anything (we have a pass to come back when it is a little clearer), this was an evening very well spent. Phil and John are so engaging! Their passion and enthusiasm for the night sky was absolutely infectious. Came away having learnt so much and looking forward to returning. Thank you

Super interesting evening where we managed to see Jupiter, Saturn and even Uranus. Very helpful, patient, intelligent and knowledgeable gentlemen that hosted the evening and willing to go the extra mile with any questions outside of the arranged evening. Throughly recommended! Still worth a visit even if the weather is against you as the classroom discussion is worth the visit alone.

What a fantastic place this is!! Visited a few weeks ago and it was so awesome. Small group of 5 of us so it was very relaxed. Host was kind, knowledgeable and very entertaining. He let guide the conversations and no question was too daft (and we did test him on this one!) Got to see some stunning photography and also look at some alien objects! Sadly it was too cloudy on our visit but the time still passed so quickly. Going through the stars and planets and showing their hi-tech telescope's. It is the perfect gift or experience to do with family or friends, I can't recommned it highly enough.
