Hiking the Pēpēʻōpae Bog Trail in the Kamakou Preserve on Molokai, Hawaiʻi
Distance: 2.0 miles / 3.2 km
In my opinion, the Pēpēʻōpae Bog Trail is why you come to Molokai. It’s one of the best trails across all the islands, but in order to enjoy this amazing experience, Pēpēʻōpae takes some planning, most notably good weather!
Since the journey to the Pēpēʻōpae Bog Trailhead is so long, I only recommend the Pēpēʻōpae hike on the clearest of clear days, and even if you do, the clouds will still dictate whether you get to see the incredible view or not.
Furthermore, just because the weather in Kaunakakai says it’s going to be clear, doesn’t mean the weather in the mountains will be clear. To know for sure, I recommend finding a good vantage point of the mountains, which you should be able to see on the short drive out of Kaunakakai to the access road mentioned below.
If on this drive the mountains are not looking clear, I recommend saving Pēpēʻōpae for another day.
How to Get to the Pēpēʻōpae Bog Trailhead?
First, the Pēpēʻōpae Bog is accessible with a 4x4 only. There’s absolutely no way a low-clearance 2WD vehicle would make it.
Second, you need to know how to get to the trailhead, which is not as straightforward as pulling up the location linked in the section below and following your GPS. In my experience, Google Maps does not know how to navigate to the trailhead, as it will constantly try to take you the wrong way through private roads, while rerouting you even when you’re on the correct road.
Therefore, instead of simply putting in the Pēpēʻōpae directions into a GPS, drive to the start of the Department of Land and Natural Resources (DLNR) access road linked below.
Google Maps Directions: Maunahui-Makakupaʻia (Access Road)
Maunahui-Makakupaʻia Access Road
From the start of the 4WD access road, it’s a long 11.8-mile (19.0 km) drive into the Molokai Forest Reserve to get to the Pēpēʻōpae Trailhead, which will take anywhere between 1-2 hours each way.
If you’re using a GPS, my biggest advice is to keep going straight and never make any turns off the main access road heading up into the mountains.
In my experience, Google Maps will repeatedly try to make you turn off the public access road and onto the private land paralleling the road, as it thinks there’s a faster route through the Molokai Ranch.
For this reason, I recommend loading the AllTrails access road map onto your phone and navigating this way, as opposed to using any GPS.
Molokai Forest Reserve
Eventually, the Maunahui-Makakupaʻia Access Road will enter into the Molokai Forest Reserve, which is probably the nicest mental checkpoint that you’re on the right road after passing through so much private land down below.
ʻIliahi (Sandalwood) Pit
Maunahui-Makakupaʻia will then pass by the culturally significant ʻIliahi Pit, also known as the Sandalwood Pit, which I recommend checking out whether on your way up or down because it’s an interesting place to learn about some of the history in Hawaiʻi; a bit of a dark history at that.
In short, ʻIliahi, or Sandalwood as it’s known as in other places around the world, is one of the most valuable woods for its oil and fragrance properties. Furthermore, Hawaiʻi is home to a third of all Sandalwood species in the world, and in order to pay back debts that the Hawaiian Kingdom had been accruing, Hawaiʻi began exporting Sandalwood, primarily to China, as a way to repay those debts.
This practice was unsustainable, and the ʻIliahi trade collapsed as many of the Hawaiian Sandalwood species were over-harvested to the point of extinction.
As for the ʻIliahi Pit, this hole in the ground was supposed to replicate a ship’s hold, so that Hawaiians knew how much ʻIliahi would fit on one ship from where it was gathered up here in the forest.
Waikolu Valley Lookout
Shortly past the ʻIliahi Pit, the next stop on the access road is the Waikolu Valley Lookout, and I highly recommend pulling over to check out the view!
This lookout is easily one of the best places to enjoy on Molokai, but another reason I recommend walking over to the overlook is that you never know if you’ll be able to see the view because of the clouds. For this reason, I suggest checking it out on your way up and down from Pēpēʻōpae in order to better your chances.
Kamakou Preserve
Immediately past the Waikolu Valley Overlook, the access road enters the Kamakou Preserve.
At this point, there’s less than two miles of driving in order to reach the Pēpēʻōpae Bog Trailhead, but in my experience, this is always the wettest and muddiest part of the drive.
If you didn’t need to put your car in 4WD up to this point, I would do it for the remaining miles.
Pēpēʻōpae Bog Trailhead Parking
When you finally make it to Pēpēʻōpae, the road will split, and the Pēpēʻōpae Bog Trailhead will be on the left shortly ahead.
All said, you can see that driving to Pēpēʻōpae is not as straight forward as simply following the Google Maps GPS directions linked below.
Plan accordingly, know that you’re likely going to have to accept breaking your rental contract to off-road, and most of all, look for good weather!

Hiking the Pēpēʻōpae Bog Trail
After the long, slow journey to get here, I think it’s nice to know that the Pēpēʻōpae Bog Trail is a very easy hike, as the entire trail follows a series of boardwalks from the ungulate exclusion fence to the Pelekunu Valley Overlook at the end of the trail.
If you’re familiar with hikes on Oʻahu, Pēpēʻōpae reminds me of the Mt. Kaʻala summit bog, but it’s simply a bit longer.
That being said, I would still anticipate coming off the hike muddy with soaked shoes, as the boardwalk will sink into the bog in unsuspecting places.
Notice
The Kamakou Preserve, where Pēpēʻōpae is located, is not only one of the most pristine native forests on Molokai but all of Hawaiʻi.
To put it into context, the vast majority of the Maunahui-Makakupaʻia Access Road ascends through a sick, dead, and dying Hawaiian forest, which is true for most areas around Molokai.
However, these high-elevation wet forests, especially here on Molokai, are so pristine and intact that I ask that you please clean off all your hiking gear before hiking Pēpēʻōpae to prevent the spread of invasive species. Please spray off any mud on your shoes, and hike in clean clothes only.
Mahalo!
That being said, since the drive is so long and the Pēpēʻōpae Bog hike is so short, I highly recommend that you take your time to enjoy the native forest.
Few trails in Hawaiʻi traverse such a beautiful native forest where the vast majority of the species can only be found in Hawaiʻi, such as Paʻiniu, shown below.
To go even further, this particular native species is endemic solely to Molokai and not found on any of the other Hawaiian Islands.
When the Pēpēʻōpae Bog Trail reaches the clearing, I think it’s a good time to look up toward the ridgeline to see what the clouds are doing.
On this day, the entire summit was socked in, but even if this is true during your visit, keep going, and you’ll see why later in this post.
In the middle of the clearing, the Pēpēʻōpae Bog Trail makes a hard right to continue toward Pelekunu Valley.
Then, when the trail re-enters the forest, it won’t pop out again until the Pelekunu Valley Overlook at the end of the trail.
Toward the end of the bog, the Pēpēʻōpae Trail will parallel this small fence line, which is a nice sign that you’re getting close!
Pēpēʻōpae (Pelekunu Valley Overlook)
After about a mile of hiking through the Pēpēʻōpae Bog, the boardwalk finally ends at Pēpēʻōpae, also called the Pelekunu Valley Overlook.
This photo is exactly why I recommend making the journey up here on the best weather days only. However, I’ve hiked the Pēpēʻōpae boardwalk a number of times and have always been lucky enough to see the view by being patient. To add to this, Hawaiʻi is typically wetter, meaning cloudier in the winter and drier in the summer. But, clear and cloudy days can truly happen at any time.
On this particular day, I only had to wait about 20 minutes for the clouds to clear before Pelekunu Valley opened up, which is one of the most mind blowing views across all the Hawaiian Islands!
Furthermore, the rest of my favorite hikes in Hawaiʻi are all located on Kauaʻi.
Pelekunu Valley
I’m not kidding when I think that the Pēpēʻōpae Bog is one of the best trails in Hawaiʻi, and this photo doesn’t even come close to showing the scale of the massive, beautiful Pelekunu Valley along the North Shore of Molokai.
Native Plants on the Pēpēʻōpae Bog
As mentioned previously, the Pēpēʻōpae Bog is one of the most pristine native forests throughout all of Hawaiʻi, which is why I ask that you please do your part to minimize your impact on this beautiful native forest.
Furthermore, some of the plants that you can expect to see in this beautiful ʻŌhiʻa-dominated forest include Uluhe, Pilo, Akaʻawa, Kōlea, ʻUki Grass, ʻĀkala, ʻĀlaʻa, and Paʻiniu, to name just a few.
If you’re interested in learning more about these and tons of other native Hawaiian plants from across the islands, I encourage you to read more in my separate post linked below.
