We started out for San Carlos Falls with a small group of friends around noon. A large part of the hike/walk was on paved or dirt roads/tracks. In some places, though, the trail was difficult to traverse due to steep terrain—even more difficult on a wet day.

The distance is only 3.2 miles round trip but we missed our turn off the paved road and had to backtrack. You’ll see a trail cut through the tall grass, follow the trail to a gravel/dirt road (.05 miles). Turn left, follow gravel/dirt road (.08 miles). Turn right, follow dirt tracks to paved road with a pipeline (.24 miles). Take a left, follow the road until you come to a fenced-in valve vault (.22 miles). Turn right, follow road to tower. To the right of tower is a trail that follows the ridge line to a forest of palms (.07 miles).

At the edge of the forest, you’ll drop down into a river valley. There are ropes along the trail to assist your descent. Hike downstream carefully. Some places are slick. You’ll reach the top of the waterfall first. There is a steep trail up the hillside that takes you down to a cool pool at the bottom.

To find the swimming hole, head down stream. When you come to the end of the stream, take a right and follow the river upstream to the swimming hole.

Parking From Agana, head south on Marine Corp. Drive (Route 1) till you reach the village of Piti. Turn left by the Veteran’s Cemetery on to Spruance Drive (Route 6). You are now heading East and up Nimitz Hill. Travel 1.7 miles up Nimitz Hill. Next you turn Right onto Larson road. As soon as you turn onto Larson Road it will dead end. A closed gate will be on your left and a field will be in front of you. Park in the field.
