What Travellers Say
Reviews Summary
Visitors rave about Tumon Bay Marine Preserve, calling it 'SPECTACULAR' and a chance to dive into an Indo-Pacific reef tank. The calm, shallow waters are perfect for families, and the abundance of marine life, including giant clams and pufferfish, is a major highlight. While conservation efforts are visible, some find the aquaculture plugs detract slightly from the natural beauty.
"Protected marine preserve. Tidal bay is walkable from one side to the other at low tide - spectacular shallow water driving at high tide. Primarily Acropora recolonisation, (young) giant clam mantles are easy to spot in the crystal clear water, wild zooanthids are starting to colonize...
Active conservation (rebuilding) efforts are thinly veiled with numerous aquaculture plugs apparent. The effort is appreciated after the ecological tragedy of the 1990s dredging...
IN A WORD? It's SPECTACULAR! If you've ever wanted to dive into an Indo-Pacific reef tank - this is your chance. You may even find yourself within 5 meters of a 2 meter long puffer fish... I'm sure he comes to dine there regularly."

"Beautiful place. Sands are really soft, so you can make cute bunny like my pic!
There are no waves because of sunken rock, and that’s why here is perfect place for family with young kids!"
