We went for a cheap daytrip to Cha-am last week. Easy to get the mini bus from Victory Monument (160b) and were down there by 11am.
It was busy with Thais being Songkran, but we found 2 nice deckchairs and parasol to set up the food drink binge.
Really amazing how cheap it was. The first round of 2 large beer singh, ice, yellow indian curry, chips, half a grilled chicken (me), and somtam, some oyster sauce salad thing and coke came to 620b. Inc. the daily rental of the chairs etc.
Lots of friendly Thais, the teenagers all happy to say 'hello, how are youuuuuu?' when the missus was off swimming.
Put away 6 large beers, tried some prehistoric horse show crab, and had a right relaxing time.
85b for large sing and bucket of ice delivered to my table. Good stuff.
The sea was a lot of fun too, good rough surf and lots of fun.
Probably cost less than 2,000b for the 2 of us.
Altogether a nice day trip from Bangkok.
