When we did the the Khao Takiab to Hua Hin walk last week, we looked for Lets Sea. It is well marked from the beach side - unfortunately, if you read my report on the Hua Hin to Khao Takiab walk a few weeks ago, you will have read about the bit of beach that was well polluted. Lets Sea is situated right above the polluted beach.Also BB, if you are still in Hua Hin, try lunch or an early dinner at the Lets Sea which is beach front about halfway from Hua Hin towards Koh Takiab.
I have to agree that it looks a lovely place to while away a late afternoon/early evening, but I don't personally fancy looking out over an oil slick. We've decided to give it a miss this time. Will check it out again next year in the event they have cleaned up the pollution there.
