I haven't been able to find any information about hang gliding in Vietnam, although paragliding seems to exist in some of the tourist areas. Is it illegal or am I simply the only one stupid enough to try? I'm pretty sure I could get a kite made there.
There were some great spots all along the QL27C that looked like it would be possible to soar all the way to Nha Trang! Same thing up around Da Nang.
