It is indeed a very good Centre, the only problems are that it has no tennis courts and there is very little (if any) information available on what sports clubs and activites are available. However i stumbled across this and thought it might help someone who wants to no more:

wow what a leisure centre, fantastic 100 station gym with air conditioning, cardio theatre entertainment system with 4 big plasma screens, punch and balance areas. Fantastic staff and very friendly, very new & modern (opened only 2 years ago), massive 8 lane 25m swimming pool with a moveable floor (whcih is great for swimming lessons and aqua aerobics - floor can change depth), excellent cafe with a healthy menu, very affordable membership options, there is a studio and sports hall where they have brilliant classes such as bodypump, spinning and many other different fitness classes. what more could we ask for!!!

It certainly looks the part! The new swimming pool is amazing if not a little confusing in its timetable. There is a huge car park so you will never not find somewere to park. Thanks to the amazing Bristol city gyms membership prices it is also really cheap. Go to any city run sports centre and check it out!

This sports centre went through a refub a couple of years ago and how offers a quality range of swimming and fitness opportunities. Two pools, one a twenty five metre, eight laned model with a movable floor to cater for children and people with disabilites adn the other a large learner pool both onside viewed by up to 250 people!
Horfield leisure also offers an exercise studio with wooden sprung flooring and spinning bikes, large multi-purpose sports hall for badminton, basketball, 5-a-side football and glass backed squash courts. There is a creche and the site caters for childrens parties, also a healthy eating cafe.
