Location: Piti Region: West-Central Difficulty: Easy Length: 10 -15 minutes Height: 50 feet up and down Sight: WWII ruins Cool Stuff: Mahogany forest

Tips: Bring loads of insect repellant and apply it very liberally to every inch of exposed skin. Wear tennis shoes as wet leaves and steps can be slippery.


From the Navy Base, Drive North up Marine Corps Drive. You will pass the turn for Polaris Point, the Port Authority, and the Guam Power Authority Piti power plant on your left. Soon after the stop light for the power plant, keep a lookout to your right for J.M. Tuncap Street.

Right across the street from Santos Park.

Take a right at J.M. Tuncap. At the end of the street turn right at Assumption Steet. Then take a left at Father Mel Street before the blue and white church.

Park under the large Saman tree on the left side of the church.

Here you will find information about the trail and a map.

This very short trail begins up the cement stairs.

After 5 – 10 minutes of walking you will discover the first of the three 14-centimeter Japanese guns.

Take the trail to the left to find the other two guns. You may also take the trail to the right (not pictured here, but shown on the map) to begin the mahogany forest walk, which has two entrances.

Next you will see the second gun, in ruins from a tree collapsing on it during a typhoon.

Keep going forward on the trail.

Here you will find the last of the guns, still green in color.

As you turn back the way you came, you may notice a trail going up the hill to your left, before you reach the second gun again.

If you’re feeling adventurous you can walk straight up the hill through the trees (there may still be trail markers posted) until you reach the top, walk through some ferns, and see an electric mast for power lines.

Immediately turn right and see a trail through the brush.

This takes you through the mahogany forest and eventually links up to the first gun area.

You can identify the mahogany trees by their leaves.

Finish the hike back down the stairs the way you came.
