The "North Open Cave" (see below) is the most accessible and the Jungle Cave is rarely visited.

JUNGLE CAVE: This is an amazing honeycomb formation in Guam’s northern coastline. It offers a twisting, winding passage snaking inland from the ocean which allows divers to explore a cave that through an interface of salt, brackish, and then fresh water. And finally a jungle hide out at the same time.

This dive requires cave diving skills and definitely requires a safety line. Divers maneuver through dark tunnels of sand, silt, rocks and stalagtites and stalagmites.

The saltwater mixes with fresh, causing a brackish area devoid of fish. Once through that, the freshwater is crystal clear. Shortly after you reach fresh water you ascend into a pool which has an entrance to the jungle.  This entrance is short, but steep and slippery.  Once you get to the top you can see out to the ocean.

*There are many remains of Japanese war artifacts here including cooking utensils, shoes, and grenades.

It’s truly an amazing experience, only for the very experienced and very lucky.

*These were found originally in 1995 and again in later visits to the site.There is very little evidence that anyone else has ever been here for a long time.

This is one of the first videos we made here (1995). It is still almost unknown to divers n Guam. Many thanks to Diedro and Mary Gicca.

NORTH OPEN CAVE  Just a little south of Double Reef is a large opening in the rock cliffline that quickly turns into an "open"  cave.  This is very easy to enter by following a large sand channel into the cave.  Once inside you'll see shafts of sunlight cascading down on the left side and hundreds of rudderfish. This cave is at least 40-50ft wide and very shallow, and the entrance is visible throughout the dive.

As long as you don't attempt to enter it when there are swells present, this is a very enjoyable beginners introduction to cavern diving.
