As has been said, Gliding is a superb way to fly, full of challenges and rewards. It does need a time commitment, but the returns are huge and Portmoak is a particularly good place to start.
They have two ridges very close by so in most wind conditions you can get extended flights, and that's without thermal and wave... I wish we had a ridge down here!
It can be frustrating at times but I promise you, Gliding is worth it once you are solo and start developing x country skills the challenges and rewards just continue to grow.
Go and have fun!
