My partner and i chose the 'B' tour and i have to say it was the one of the best experiences of my Phuket holiday. We were meet by the very friendly staff and were given an entertaining breif on saftey basic techniques used. After that i could'nt remove the smile from my face, The zip lines were so much fun and the guides were absolute characters. The equipment used was 1st class and at no time did i feel unsafe. The guides were constanly checking out equipment and at no time were we unhoocked from any saftey lines. I recommend doing the 'Superman' on either the 200 or the 400m lines. Oh and i didnt make it all the way to the platform on one particular zip line but the guides are very skilled in retreiving you i that does happen.
Water was provided during the adventure as well as insect repellant but surprisingly there wasent to many mozzies when we were there. Make sure you DONT forget to take your camera. The photo opportunitys are to good to miss.
