Whale Watching (ดูวาฬ) Duration from October to February coincides with the period of water compression (according to vernacular, "water compression" will take place during the time that tide in the Gulf of Thailand will spin out of Samut Songkhram and Phetchaburi Provinces. Animals that are feed for whales would come out along). With any luck, it is possible to watch Bryde's whales come out to find feed on the coast of the Gulf of Thailand. Going on a cruise for watching these whales with mouths fully open above the water surface to stalk prey (anchovies and krill) is an impressive experience. There are cruise service both at Hat Chao Samran and Laem Phak Bia piers.
