Been here twice with the grandchildren. It is the most fantastic place for the kids and they learn so much whilst having fun. I can't believe this almost closed due to lack of funding. The kids have a great day out here, you can't get them to go home. Only, bit of advice is if the weather is gloomy take warm clothes as the wind does whistle across the outdoor attractions.

This is a fantastic spot for both kids and space-loving adults. We were lucky enough to have a clear night and saw Saturn’s rings and Jupiter through telescopes. It was absolutely breath-taking. Beyond the historic equipment, there are tons of hands-on science exhibits to keep the kids engaged. Highly recommend for a family night out!

Really enjoyable science centre that might be in need of a bit of a refurbish, but there's plenty to do for all ages and lots of interactive apparatus. Make sure you go on a clear day as there are some good outside bits and exhibitions to explore. Well worth a visit, especially if you are interested in space and physics. The café isn't badly priced and there are plenty of picnic benches so you can eat your sarnies on a dry day. 🌌

Great day out, Bank Holiday Monday, took a friend's children 3 & 7, they had a great time with all the hands on (inside and outside) exhibits. We'd not been for years, nothing had really changed, but still great fun, there for about 5 hours (brought our own picnic lunch, plenty of outdoor and indoor picnic tables), weather was a bit unsettled but that's why we went, instead of to a local park as there is a lot to do indoors if weather bad, and can do outdoors when sun came out, which it did when we visited the 'Sun Telescope' 🔭, also had a free tour of two other telescope domes......would recommend for anyone with Year 6 or below children, although the adults had fun as well.

Wasn't sure what to expect, we visited without any children. We had a really fun time with so many things to try. If you like finding out how things work, pressing buttons, pulling levers and playing games then this is well worth a visit. Food choices were limited but what we had was tasty. The telescope tour was fascinating and kept adults and kids interested. Plenty to do, inside and out so a great place to visit whatever the weather.
