Rim Phae Beach
When you want to enjoy and relax on the beach in South Eastern Thailand mainland, forget about Pattaya which is too crowded. Rim Phae Beach or Hat Rim Phae will be the perfect choice.
Away from bustling Bangkok and Pattaya, Rim Phae Beach provides long sandy beach, several hotels/villas/cottages, and great view to Koh Samet and 5 other smaller islands in the gulf of Thailand.
There are also several local/seafood restaurants should you need something to eat.
And for the activities, you can do swimming, riding banana boat, or rent a boat to go to small islands for skin/scuba diving.
