As you enter the beach you will find a couple large Japanese WW II gun bunkers. Between the bunkers and just off the beach is an ancient Chamorro village site. Here you will find several latte stones. It is believed that they built their houses on top of these stones. You can walk further inland from the old latte stone site and find a couple interesting small caves. A large paved parking lot with a security guard was recently added.

The Obyan area also has nice hiking trails. One trail navigates up the cliff to Naftan Peninsula. Another trail led me to this small hole in the ground (pictured to the right-top). It is a Japanese WWII exit tunnel which originates from an oceanside cave (right-middle). The cave is on a beautiful remote beach (right-below). More trails lead to other small beaches, WWII building foundations, and spectacular views.
