Cant find a page dedicated to the raftng but this is the 'tour' wouldnt want to get caught up in going to 'rubber plantations' and other tour type shite tho... Can find thier direct contact as GF used to work as a tour agent and would know who to call..
You have me thinking about doing something a bit different also now... Hmmm.. Fireblade round to Lanta for 2 nights ?? Jeep for white water / elephant.. One night jungle stay.. one night Krabi...
Really is loads to do if you get your head out of the bottle occasionally..
