Hat Saikaew beach is on a Royal Thai Navy base, 20 kilometres South of Jomtien Beach. It's a very pleasant scenic drive when on the base, almost European in parts, and is in a well tended natural setting. Access to the beach is 30 Baht for Thais and 80 Baht for foreigners.
The beach was over crowded with Russian tourists the day we went and their boats clogged up the bay.
The Water however was still cleaner and more sparkling than further North in Jomtien.
