If you want to learn to hang glide then your best bet is to go to a BHPA registered school. The BHPA maintains a list of all registered schools in the UK along with appropriate contact information; this is the best starting point. The next step is to research your chosen school a little. Find out what sites they use and do they have sites suitable for all wind directions? How much do they charge (daily or a flat fee for the entire course)? If possible, see if you can get recommendations from someone (you may find there is a local hang gliding club that may help here), some schools are much better than others!
