Overview
About Tumu Mountain Trail
Why go
- Leolo Ridge opens onto Ofu’s coral lagoons and the three Manuʻa islands.
- The rainforest ascent builds to a distinct rocky ridge lookout.
Heads up
- A steep, humid climb and difficult route-finding make this a hard half-day hike.
- The trail is outside the park boundary, with limited verified access and parking details.
Tumu Mountain Trail is a challenging out-and-back from near Ofu Harbor, climbing through rainforest to Ofu’s high ridge and continuing to the Leolo Ridge lookout. The full hike is listed at 5.5 miles round trip, including the quarter-mile extension to the rocky outcrop. Allow about four to five hours; it’s a steep, humid half-day, not a casual viewpoint walk. I’d choose it for the island-and-lagoon panorama, not for an easy summit stroll.

Hiking Tumu Mountain Trail
From harbor road to high ridgeThe route follows an old road uphill from the harbor side, then narrows into forested trail.
The route follows an old road uphill from the harbor side, then narrows into forested trail. The canopy hides most of the view during the climb, so the payoff comes late. Blue markers identify the established path. Take care at junctions and ask your Ofu host about the current approach before setting out; this trail lies outside the park and is not maintained by park staff.
Continue to LeoloAt the high point, continue about a quarter mile on the marked extension to the Leolo Ridge…
At the high point, continue about a quarter mile on the marked extension to the Leolo Ridge rock outcrop. That is the named-viewpoint finish, with a short rocky approach. A separate, rougher spur continues toward the radio installation and true summit area; it is not the Leolo overlook. Return the way you came.
The viewFrom Leolo, look across Ofu’s coral lagoons toward the three Manuʻa islands.
From Leolo, look across Ofu’s coral lagoons toward the three Manuʻa islands. From a safe spot, frame the lagoon below through the ridge foliage and keep the distant island silhouettes on the horizon; that gives the reef its sense of scale.

The trail starts near Ofu Harbor, but a designated parking lot and its capacity aren’t confirmed. Public parking at the harbor has been reported; ask your lodge or local host where to leave a vehicle and arrange transport in advance. The island has very limited services and no restaurants, so sort out food before the hike. No dependable water source is documented along the route.
