Bohey Dulang is the kind of place that changes your photos. This 7-hour Semporna outing mixes a 600m island hike with calm-time swim stops and optional DSD scuba and snorkeling, all wrapped around the views you can only reach by boat. You’ll also get a simple onboard meal tucked into the day’s pace.

I love how the schedule gives you two different ways to experience the islands: the trail to the summit viewpoints, then the water for reef life and clear-sea swimming. I also like the small, practical touches like multilingual guidance (Chinese, English, Malay), plus masks and snorkels so you can get in quickly.

One consideration: the hike and time in the water are weather and policy dependent, and the water sessions can feel short if you’re an experienced snorkeler or you’re hoping for long open-water time.

Key things to know before you go

• Bohey Dulang summit hike (up to 600m) for panoramic views over the Celebes Sea
• Two swim stops, with snorkeling or instructor-led DSD scuba sessions (time varies by option)
• Mantabuan island relics tied to former sea-gypsy life patterns
• Sibuan Island snorkel at a remote bay with blue sand and underwater fish-rich areas
• Order can change based on tide and lunch timing, decided by the captain
• Park rules can cancel the hike, shifting the day to snorkeling only

From Semporna Jetty to Tun Sakaran Marine Park: how the day flows

Most days start at Jeti Pelancong Semporna Jetty. Plan to arrive a bit early because you’ll do a brief registration process before boarding, and the crew needs your full name and nationality for the day’s permits and operations. The tour is designed as a tight, full-day circuit, not a slow beach lounge—so if you like structure, you’ll probably enjoy it.

Once you’re on the speedboat, expect roughly 80 minutes of travel out toward the Tun Sakaran Marine Park area. The ride is part of the experience: it’s when the day’s mood shifts from “planning a trip” to “this is really happening.” If you’re prone to motion sickness, take prevention ahead of time and bring what you need.

The crew can modify the itinerary based on weather, sea conditions, and government/policy rules. That’s not a cop-out; in this region, conditions are real, and the day is safer when the operator follows them.

Bohey Dulang hike to a 600m viewpoint: the best reason to book

Bohey Dulang is the centerpiece, and the hike is the main ticket to the top-side payoff. If conditions allow and you’ve selected the hiking option, you’ll hike along about a 600m trail with scenic stops and a guided walk. The duration shown for the Bohey Dulang segment is about 75 minutes, and the pace is built around mixed groups.

What you get here is the view you can’t fake from any beach: a panorama over neighboring islands and the Celebes Sea’s crystal-clear water. From the upper area, you can see a combination of turquoise-blue lagoon water and the island’s other volcanic shapes. Even if you don’t love hiking, the viewpoint is usually why people keep signing up.

A practical note: you’ll want hiking shoes and a waterproof bag. You’ll also want a change of clothes for later because the day runs from boat to water to warm lunch shade and back again.

If the hike is canceled due to national park rules, you don’t lose the day entirely. The plan can shift to snorkeling/diving-only, and the operator indicates that if hiking doesn’t happen, you won’t need to pay hiking permit/entry fees that day. Still, if you booked no hike, you’ll have to wait at the jetty—requests to join the hike at the last minute aren’t possible due to permit issuance requirements tied to specific hiker names.

Mantabuan: swimming and your first reef moments

After Bohey Dulang, you head to Mantabuan Island for a shorter stop (around 35 minutes). This island carries a story tied to former sea-gypsy life—so it’s not just a pretty shoreline break. You’ll see remnants, including crumbling brick that points to that long-ago community that lived much of their routine at sea and rarely came ashore.

Then the water time starts—either as basic snorkel or as part of the optional instructor-led DSD scuba experience (depending on what you selected). You’ll get a safety briefing and then plunge into the blue with provided equipment.

One thing I like about this setup is that Mantabuan functions as the day’s “warm-up” reef stop. You’re already in the island-hopping mindset, so the switch from land views to reef viewing feels natural. If you’re choosing between snorkeling and DSD scuba, remember: the itinerary is built around multiple stops, and the water segments are time-managed.

Also, the boat captain may run the order and timing based on tide and lunchtime. So even if the itinerary looks linear on paper, the day can feel a little flexible in the real world.

The lunch + break phase: where the day actually resets

Next comes the long-ish break time and lunch segment, about 1.5 hours on the itinerary. The operator mentions that lunch is served in the shade of a canopy, with a lunch box plus at least 1.5 liters of water during the day.

This is more important than it sounds. After hiking and a first water stop, you need a temperature reset, dry-off time, and a chance to regroup before the final snorkel/reef push. If you’re the type who gets cranky from saltwater fatigue, you’ll appreciate this breathing space.

What to watch for: lunch quality is described as “okay” by at least one person, and another suggestion is to bring snacks if you’re picky about meals or you know you’ll get hungry between swim stops. Even if lunch is fine, your body may still want a little extra energy.

Sibuan Island: remote bay snorkel with blue sand and stone arch views

Your final island stop is Sibuan Island, scheduled at about 40 minutes on the itinerary. This is described as a remote place that even many locals rarely see, which usually means less crowded water and a more “you’re here for the sea” atmosphere.

At Sibuan, the snorkel experience gets specific:

• You may snorkel near a secluded blue sand beach
• You can spot a stone arch beneath the coastline
• Underwater, you might see formations and thousands of colorful fish in reef-rich areas

In plain terms, it’s the stop that most strongly rewards good buoyancy habits and patience. If you rush, you’ll miss the fish activity. If you stay relaxed and keep your eyes scanning for movement, the underwater scene can feel like a living aquarium.

If you chose snorkeling, you’ll typically be in the water during these stop windows, and the captain decides the best spots based on weather and conditions that day. The captain’s job here is real: wind and current can change where you’ll have the calmest water and best visibility.

DSD scuba (optional): fun for first-timers, time-limited by design

If you select scuba, the tour includes 2 DSD scuba trips of about 20 minutes each with an instructor, plus safety briefing time. The equipment listed is practical and complete: fins, BCD regulator, wetsuit, gauge, and oxygen tank, and you also get a life jacket and instruction in multiple languages.

If you’re a complete beginner, this is often a sensible way to try scuba without needing a prior certification, since no scuba certificate is required for DSD. And one review specifically mentioned an instructor named Din as excellent for first-time scuba participants—so if you’re hoping for hand-holding and clear guidance underwater, you’re likely to be well supported.

Just don’t go expecting a long, hours-long underwater session. The itinerary is built around multiple stops, and the scuba time is intentionally short enough to keep the group safe and moving.

Getting your money’s worth: price, included gear, and the fees you should budget

At about $58 per person, this tour packs a lot into one day: boat transfer time, multiple island stops, guided hiking (if allowed), swim time, and a lunch box. Value-wise, it comes down to whether you’ll use the options.

What’s included:

• Optional DSD scuba: 2 trips (about 20 minutes each) with instructor and gear
• Optional snorkeling: 2 snorkeling trips depending on selection
• Optional hike: when conditions allow and if selected
• Swim stops all along the day
• Multilingual instruction on snorkeling/scuba basics
• Life jacket
• Mask and snorkel
• One bottle of water (1.5 liter)
• Lunch box
• Dock taxes

Fees you should plan for (not included):

• Tun Sakaran Marine Park fee RM30 per person
• Bohey permit and climbing fee RM50 per person (only if hiking is available)
• Bohey insurance RM7 per person if required by updated park regulation (only if hiking option is available under park rule conditions)
• Tun Sakaran Marine Park diving fee RM150 for foreigners or RM100 for locals for scuba only (explicitly not for snorkeling)

This is the important value math: if you’re only snorkeling, the scuba-only diving fee doesn’t apply. But if you choose DSD scuba, you should budget for that extra park fee. Also, if the hike gets canceled due to park rules, the operator notes you may not need to pay those hiking-specific permit/insurance fees—so your final cost could be lower than the hike-at-yes planned scenario.

What to pack so the day feels easy (not annoying)

Bring a small kit that matches the rhythm of boat + hike + saltwater. At minimum:

• Change of clothes
• Hiking shoes
• Waterproof bag
• Cash
• Passport (a copy is accepted)
• Motion sickness prevention
• If doing scuba: wetsuit (listed as something to have)

Also, a towel and a dry shirt can help a lot even though the operator already provides core gear for snorkeling/scuba. The day gets salty and warm; you’ll want comfort when you’re back on the boat.

If you have any respiratory issues, this tour isn’t suitable according to the activity’s guidance.

The day’s real vibe: friendly crew, but group timing can vary

The overall feel in the feedback is consistently positive: friendly guides, supportive help in the water, and a strong sense of safety. One person highlighted good communication across English and Mandarin, while another noted that some guides had limited English beyond a few words. In practice, that means you should listen closely during the safety briefing and don’t be afraid to ask basic questions even if your shared language is limited.

One more practical note: if you’re sensitive to waiting around, be aware that group logistics can create idle time. A review mentioned longer waiting than expected for people to get changed and ready. That’s the downside of sharing a small boat experience with a group—timing depends on everyone in it.

Should you book this Bohey 3 Islands hike + snorkeling/scuba tour?

If you want a one-day package that combines land views and reef time, this is a strong choice. The Bohey Dulang hike is the main reason to book, and Sibuan Island is a great closer for your snorkeling payoff. You’ll also get a structured day with safety briefings, provided masks, and a captain who adjusts spots based on sea and weather.

I’d skip it or choose carefully if:

• You’re hoping for long, uninterrupted water time (sessions are time-limited)
• You’re vulnerable to respiratory problems
• You dislike group pacing and could be annoyed by waiting for the next step

If you’re flexible, like your days active but not exhausting, and you’re excited about reaching viewpoints and reef sites that aren’t practical without a boat tour, you’ll probably leave happy and tired—in the best way.
