I got the 0940 bus to Erawan which lasted 2 hours on a local bus which kept on stalling and not starting. It even had to be pushed at one point. The falls themselves are stunning and stretch for over 1km upstream. Some of the plunge pools are big enough to swim in. I swam in the first major one I got to (tier 1 or 2); it took a while to pluck up the courage to go in as the water was milky-blue so I had no idea of depth. Secondly there were loads of fish. This on its own didn't bother me; it was just that they kept on biting me! I swam across and stood on the rocks underneath the curtain of water, it was very cool. I trekked through the forest to some of the other tiers. I don't think I reached the end as it was too far away and I was dehydrated.
I got back at about 1530 after not eating anything since breakfast, which was just toast. I wolfed down a tuna baguette, had a shower and finished my current book. So far I have read The Godfather (Mario Puzo), Fury (Salman Rushdie), The Long Way Round (Ewan McGregor and Charley Boorman), The Runaway Jury (John Grisham) and an Agatha Christie book. I sat and had diner with the Danish guy from yesterday and an Irish guy who was on his way home after 5 years of working abroad.
I've decided to delay my plans a day and go to Sukhothai the day after as I'm tired and could do with a day of doing nothing.
