Cetti Bay Overlook
A roadside lookout over an undeveloped southern bay and the red hills behind it.
Updated 3 September 2026
The Cetti Bay overlook sits on the coast road in southern Guam, looking down on a bay with no road to it and nothing built on its shore, backed by the red-earth hills that give southern Guam its distinctive look where the savanna has been burned repeatedly and the laterite is exposed. A steep trail runs down to the bay for those who want it. Most people stop at the top.
What to look for
- The undeveloped bay - a shoreline with no road or building on it.
- The red hills - the exposed laterite of southern Guam's savanna country.
- The reef - the coral edge visible offshore from the height.
- The trail down - the steep route to the bay for those who take it.
When to go
December to June is the drier season. Late afternoon light on the red hills is best. The trail down is dangerous when wet.
Practical notes
The trail to the bay is steep, unmaintained and slippery; most people should stay at the overlook. Parking is roadside and limited. There are no facilities.
Nearby
Sella Bay is north, and Umatac is south.
