Pa Sai Beach is very first beach in the eastside about 8 kilometers away from Manoh Pier and 1 kilometer from Laem Sai Beach.They also nearby to Ao Sai Beach and Coconut Beach. Well, not walking distance but should be around less than 15 minutes drive.
It wasn't crazy crowded and the water was warm. Got there around 9am and it was empty.However, by 10, a lot more people had arrived. We stayed in front of the restaurant and had free chairs because we ate lunch there. Beers are cheap and quite a picturesque place.
