Although our $19/day hotel cost leaves us a lot of room for spending, we still didn't want to spend 3300 baht/pp so we went with the 1990 baht Jungle Flight and was not disappointed. By the way, there were also plenty of Asians in our group. :). They picked us up promptly at 8 am and took about an hour of mountainous nausea-inducing drive to their home base. We quickly got outfitted with the proper gear, including a very "attractive" pink net to wear over our hair before putting our helmet on. After getting the waiver signed, we got a short briefing and we were on our way to the 22 different platforms. Most of them were zip lines atop or amongst very tall trees. The view was breathtaking. We also crossed swinging bridges, went down spiral staircases built into the tall trees, and finished off with a 100-foot free falling rappel station that we had to jump off of. We spent about 2.5-hours zip lining, just in time to hike back UP the mountainside for a lovely traditional Thai meal, buffet style. We even got a commemorative t-shirt. The staff were entertaining but professional and the whole experience felt safe. We were back in our hotel, 6 hours later!
