Leeds Sailing and Activity Centre is a great place to know about, especially if you live in or around Leeds and have children. It is also great for people in who have time during the week or Saturday mornings for watersports classes. You do not need to live in Leeds District to go to classes there. During the April, May, summer and October break, they offer activities for childen, including some very reasonably priced week-long summer camps that enable children to sample many of the different activities they provide. The centre offers a very broad range of activities: indoor caving, biking, raft-building, standup paddleboarding, among other things. After doing a multi-activity camp, my son went back for some additional classes and now has Royal Yachting Association qualifications in dinghy sailing and British Canoeist Union qualifications in paddlesports (canoeing & kayaking). We also held his birthday party there for a few years (1 hour of watersports for a group, followed by takeaway pizza and cake in one of their rental rooms) and everyone enjoyed it. I have done (adult) paddlesports classes there and the training was very thorough. There are a lot of other classes on offer, too: windsurfing, rowing, bell-boating, and (during the offseason) powerboating. They do a lot with handicapped groups, too. The only downside to LSAC is that they share Yeadon tarn with the Yeadon sailing club, so don't run classes on Saturday afternoons or Sundays. The full range of classes is available on a PDF that is downloadable from the Leeds City Council website for booking ahead and you do need to book in advance because courses get pulled if too few people sign up. read more
