Hiking the Puʻu Pehe Trail (Sweetheart Rock) on Lānaʻi, Hawaiʻi
Distance: 0.9 miles / 1.4 km
The Puʻu Pehe Trail, more commonly known as the Sweetheart Rock Trail, is an iconic Lānaʻi day hike and a favorite among both locals and visitors alike—especially at sunset!
Beginning at Hulopoʻe Beach on the South Shore of Lānaʻi, the hike up to Sweetheart Rock in Mānele is almost always known for it’s beautiful, sunny weather. This is why I recommend hiking Puʻu Pehe if the weather for other hikes on the island—such as the Koloiki Ridge Trail or the Hiʻi Trail near Lānaʻi City—isn’t looking as good.
In any case, I think the photo below speaks for itself! This is why, if you have the flexibility to hike to Sweetheart Rock at any time of day, choose sunset—you won’t be disappointed!

Parking for the Sweetheart Rock Trail is located at Hulopoʻe Beach Park, which is open to the public, regardless of whether you are staying at the Four Seasons next door.

Hiking the Puʻu Pehe Trail
The Puʻu Pehe Trail begins on the far south side of Hulopoʻe Beach, following the same path that leads to the tide pool.
On a different note, be aware that the entire area—from the Fisherman’s Trail, Hulopoʻe Beach, and the Puʻu Pehe Trail out to Mānele Bay—falls under the Mānele-Hulopoʻe Marine Life Conservation District, where dogs are not allowed.
This will make more sense further into the hike.
Technically, there is an option to park a little closer, but it’s not really worth the effort.
Hulopoʻe Tide Pool
After just 0.2 miles (0.3 km), the Puʻu Pehe Trail to Sweetheart Rock passes by the stairs that lead down to the Hulopoʻe Tide Pool, which I highly recommend spending some time in as you explore the South Shore!
Warning
Do not leave the trail.
One of the reasons this entire area is protected under the Mānele-Hulopoʻe Marine Life Conservation District is to protect Hawaiʻi’s native Wedge-tailed Shearwaters, which nest right alongside the trail—meaning that stepping off the trail could crush their nests and the birds inside.
This is one of a few reasons why I previously mentioned that dogs are not allowed.
The unique opportunity for hikers to easily see Hawaiʻi’s Wedge-tailed Shearwaters right next to the trail is truly something unique to Lānaʻi.
That said, please do not get too close or disturb them in any way.
For context, this photo was taken right in the middle of the trail using a 300mm lens.
These are the nests that can be seen lining the Puʻu Pehe Trail to Sweetheart Rock.
At roughly 0.3 miles (0.5 km), Puʻu Pehe (Sweetheart Rock) becomes visible for the first time, where the trail makes this big left turn to begin the hike up to the summit.
From the start of the hill up to the top, the Puʻu Pehe Trail gains roughly 100 ft. (30.5 m) on this final stretch.
If you look closely, native Hawaiian plants like ʻIlima and Alena can be seen growing throughout this rocky landscape.
Puʻu Pehe (Sweetheart Rock)
At just under 0.5 miles (0.8 km), the Puʻu Pehe Trail ends atop the 125-ft. (38 m) cliff overlooking Puʻu Pehe, the small islet just offshore.
As previously mentioned, Puʻu Pehe is one of the best sunset hikes on Lānaʻi, with winter sunsets being slightly better than summer, due entirely to where the sun sets based on the time of year.
However, don’t let a summer visit discourage you from hiking Puʻu Pehe for sunset, as I truly believe the cliffs along the entire last half of the hike are among the best places to enjoy the sunset on Lānaʻi throughout the year.
Warning
While it may seem like the best viewpoint is closest to the water, the edge of the cliff toward Puʻu Pehe is very unstable.
On top of this, the ground slopes down toward the cliff and is covered with small, loose rocks, which can cause one to slip.
I say all this to emphasize that getting close to the edge just to take a photo is truly not worth the risk, as there are much better angles for photos of Sweetheart Rock on the hike along the beach below, as opposed to the top.
Native Plants on the Puʻu Pehe Trail
The Puʻu Pehe Trail to Sweetheart Rock has a few native plants that hikers can look out for, with a number located right near the trailhead at Hulopoʻe Beach Peak.
Some of these include ʻIlima, Naupaka, Niu, Alena, and Kou, to truly name just a few.
