Japanese Artillery Gun in a Piti Jungle Photo: NPS
A short and easy hike through the jungle will lead you to three Japanese Vicker type 140 mm coastal defense guns. During the Japanese occupation of Guam from 1941-1944, the Japanese built up defensive positions on the island. The CHamoru population was forced to work in building up these defenses, and did so here at Piti Guns . This same area was used as an Experimental Agricultural Station. The station was established in 1909 and funded by the USDA.
Accessibility The cleared trail includes concrete staircase sections as well as uneven limestone surface.
The lines are the National Park Service's public trails layer, the trailheads and the waterfalls, views, peaks and historic places along them the Service's public points of interest, read 2026-10-16 and simplified for the map; the length is the line's, end to end. The write-ups are the Service's own "things to do" text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the park's own site before you go.
