This has to be one of my favorite spots on the Big Island! Pololu Valley was created from an area of erosion on the northern side of the island. The trail down into the valley is a strenuous 0.6 mile hike with a 420 foot elevation change. Just remember, you have to come back up. But once you get to the valley, you are rewarded with a secluded black sand beach that is amazing.
In case you don’t want to or can’t make the trek down, there is a lookout so you can see the beauty of the valley and black sand beach.
There is no fee to enter Pololu Valley. But parking is challenging. Get there early to avoid parking issues.
Tip: Take hiking poles to make your descent and ascent easier.
