I used to fly Hang Gliders until marriage got in the way. When your nearest site is 60 miles away and you are not too sure on the weather, they start to object that you take a whole day out, especially when you don't fly.
That said, Hang and Para gliding are probably the purest forms of flying. You don't need any help to get airbourne. To stand at the top of a hill,take a few steps to get in the air and a few minutes later touch the clouds is a brilliant experience. Then to fly several miles across country using you own abilities and skills just completes it. You don't get many better experiences in life. Some say sex is better, but it doesn't matter how good you are, it doesn't last as long as hang gliding
The question of safety is always raised and I have hurt myself once or twice. I have also hurt myself just as bad playing football etc so its no different. Like most things in aviation, if you obay the rules you will be okay. If your equipment is maintained in good condition you won't have any problems and Hang Gliders are extremely well built these days. They may look flimsy but they can take a lot of stress. People who criticise them tend to think of them as made from bamboo and polythene (which the first ones were). The current distance record for a Hang Glider is 700Km and height gain is over 4000 meters. If they can fly that far and high they must be good.
Microlites are subject to more scrutiny and regulation. The CAA/FAA etc wouldn't put up with them if they were flying death traps. They are an excellent way to fly under power and it is relatively cheap and really convenient. You can keep it at home and if the mood takes you, you just hitch it up to the car and off you go to you nearest field (owner permitting of course).
Its definately worth trying so give it a go.
