Quick answer
Tun Sakaran Marine Park is open 08:00 to 17:00 every day, and the Bohey Dulang climbing fee is 50 MYR per person for international visitors. The park recommends arriving between 08:00 and 10:00 to start the ascent before midday heat builds and afternoon rain can close the trail. The hike to the crater-rim viewpoint takes 30 to 45 minutes depending on pace and trail conditions.
Bohey Dulang is one of eight islands gazetted under Tun Sakaran Marine Park in 2004, and the only one in the cluster with a marked hiking trail to an elevated viewpoint. The summit overlooks a submerged volcanic crater surrounded by coral reefs and shallow turquoise lagoons, a formation that gives the park its reputation as one of Sabah's most photographed seascapes. A bohey dulang day trip typically begins at Semporna jetty, where island-hopping operators load passengers onto wooden or fiberglass boats for the 30- to 45-minute crossing. Most itineraries bundle Bohey Dulang with snorkeling stops at Sibuan, Mantabuan, or the sea-gypsy village on Bodgaya, so the climb itself occupies only a two-hour window within a longer tour. The trail ascends 353 meters through secondary forest and exposed limestone outcrops; wooden steps and rope sections mark the steeper pitches, but the route is unshaded and the final push to the rim can be slippery after rain. Park rangers station themselves at the trailhead to collect the climbing fee and monitor group size, and they will turn hikers away if storms are forecast or if the midday heat index exceeds safe thresholds. The viewpoint itself is a narrow ridge with drop-offs on three sides, wide enough for a handful of visitors at a time. Photography is best in the morning when the sun is behind you and the water reflects the full gradient from pale jade to deep cobalt. By early afternoon, the angle flattens and haze from the Sulu Sea dulls the contrast, so the park's recommended arrival window is not just about heat—it's about light and visibility. Descent takes 20 to 30 minutes, and most operators allow 90 minutes total on the island before returning to the boat for the next snorkeling site. Because Bohey Dulang sits within a gazetted marine park, visitor numbers are managed through the tour-operator licensing system rather than on-island ticketing. The 50 MYR climbing fee is separate from any snorkeling or boat-hire costs and is collected in cash at the trailhead. No food or water is sold on the island, and there are no facilities beyond a basic ranger shelter, so everything needed for the hike must come with you from Semporna.

Step-by-Step Guide for a Bohey Dulang Day Trip Hike
The hike to Bohey Dulang's summit viewpoint involves a steep 30–45 minute climb covering approximately 600 steps through forest and rocky terrain. Most visitors complete the round trip, including time at the viewpoint, in 90 minutes to two hours.
Register at the park office
Upon arrival at Tun Sakaran Marine Park, present your ID and pay the 50 MYR climbing fee at the registration office before accessing the trailhead. Many visitors forget to bring exact change, which can delay the group.
Begin the ascent early
Start the climb between 08:00–10:00 to avoid midday heat and potential afternoon rain that may close the trail. The first section is the steepest, with wooden steps and rope assists through dense forest.
Pace yourself on the steps
The 600-step climb includes uneven stone sections and露root crossings that become slippery when wet. Rest at the two marked platforms if needed—pushing too hard in humidity leads to exhaustion before the summit.
Reach the summit viewpoint
The final stretch opens to a rocky ledge overlooking the turquoise lagoons and surrounding islands. Most visitors spend 15–20 minutes here for photos before descending via the same route.
Descend carefully and check out
The descent takes 20–30 minutes and requires attention on loose gravel sections near the top. Return to the park office to confirm your exit before departing the island.
