Amazing inland sailing venue on a resevoir. The resevoir provides excellent dingy sailing. The surrounding hills are relatively clear and therefore the wind is pretty constant. Also, due to the height, the wind tends to be pretty strong.
The club runs open events that non-members can attend. They also run training courses, but I'm not sure if these are open to non-members - check with the club.
The club has very recently built a new club house which has fantastic facilities. The views across the resevoir are stunning from the club house's upstairs social area. The club house also uses innovative environmental features (for instance, solar panels and a ground source heat pump).
