Traveller reviews

“A really memorable two weeks diving and staying with Hydronauts”
21 Jul 2025
The whole ambience around this fantastic dive resort is lovely. Friendly helpful staff, lovely location right on the beach, with long tail access to the large spacious Hydronauts Five Boat. The Barracuda restaurant has wonderful and varied food overlooking the bay and Hydrate bar with bean bags is perfect for sunset drink. Dive centre is very professional with really friendly and helpful instructors and dive leaders. Rooms are spacious and clean with a/c, coffee, good WiFi and a really comfortable bed :)

“Quiet confortable place in the diving paradise”
14 Jun 2025
We had a confortable stay. The room was wide and quiet, with a confortable bed and a handy little fridge. Plenty of services around, ATM, 7eleven, nice restaurants, motorbike renting, scuba diving schools (one in the same hotel). You can book snorkel and diving tours, they pick you up from the hotel reception. The staff was very kind. They allowed us to check-in a little earlier, as soon as they could have the room prepared (we arrived in the overnight ferry). They also answered all our queries patiently and managed booking the ferry to Bangkok for us. We really appreciate their kindness and good disposition.

“Disappointing”
10 Jun 2025
The room had a nice balcony with a great view of the Chalok Bay.

“Comfortable but wouldn’t return.”
30 Apr 2025
I loved how close the resort is to the 711 and surrounding Restaurants and moped rental. The AC was great (when there was electricity) and the rooms were clean. You can walk to shark bay and freedom beach if you can manage the heat and hills.
