Why should you go there and how do you do it right?

Sai Noi is the small bay I would recommend if you want to swim in Hua Hin. It lies below Khao Tao hill, about 16 km south of the city, and is a half-hour drive away. It's a short, soft sandy beach nestled between rocky headlands, where the water is clearer and calmer than on the long city beach. The name means "small sandy beach," and it is indeed small – and that's precisely its charm: On weekdays, you'll share it with a few Thai families and some long-term guests from the holiday apartments behind Khao Tao.

There isn't much here, and that's intentional. You can rent a few sun loungers and parasols on the beach, and behind them are some small Thai food stalls and cafes. The temple and the Hat Sai Noi Khao Tao Viewpoint on the hill above are just a short climb away if you want to enjoy the view over the bay. Khao Tao Beach and Suan Son Pradiphat are both just a few minutes' walk into town if you fancy a longer stroll.
