It exists here in the US.
Also in NZ. I did a five-day Mountain Soaring Course in Omarama.
Attend the pilot's meeting, attend a course lecture, walk out to my glider, which was already on the line, fly for several hours, land, leave the glider with the crew and walk back for a beer.
I did 17 hours in five days with my "own" Duo Discus and instructor. Flew about 1500 km and learnt a lot. However, it's not cheap - about $200 per hour.
Most of my gliding though, has been in a club environment and I recommend that for long-term learning and just plain socializing.
vj,
You might consider going on an intensive course to get started, but ultimately, join a club near you that has the "right" atmosphere.
