Hey. we got to wiatomo yesterday and went straight black water rafting. this meant we got in a wet suit and helmet and light then went to a cave and started walking down underground. it was really cold. we got so far then you have to put a car tyre inner tube around your waster and begin to float down the river thats inside it. you begin to see the glow worms. then you all get to a water fall bit and you have to jump off into the dark with your tyre. it was quite scary cos you dnt know how deep it is and stuff or how far your actually falling. i had to go first which is always nice. then you all link up and float with your lights off and watch all of the glow worms on the roof. its very nice. we floated till we got to another area that had a huge slide down it and we went down there and then we were out. its a unique experience which i enjoyed. but luckily its the only place in the world you can do this so never again. hostel is also clean here so its nice. slept for 15 hours last night. speak soon. nearly at Ralphs now.
