December 2, 2025, 1/4 Mile Viewpoint

This is the first of many great viewpoints along the Kalalau Trail. After a bit of a climb from the trailhead, it’s a perfect spot to stop and admire the beach, reefs and lagoon and snag a photo.

Hāʻena State Park is home to a range of activities, including sandy beaches with snorkeling, coastal views, and access to waterfall and forest hikes along the Kalalau Trail. Visits to the park require advance reservation. Non-residents need to purchase both a park-entry pass and a parking or shuttle pass for the park. If parking slots are sold out, there is an official shuttle that includes park entry and drops you directly at the trailhead/park gate.

A fantastic tour through a wonderful botanical garden. Hiking boots and, if necessary, hiking poles are very helpful. If it has rained in the previous days, you'll be walking through muddy terrain. Plan on two hours each way.

Not a trail for beginners. Sturdy shoes are necessary. But they don't have to be alpine hiking boots. Trail running shoes are recommended - not waterproof ones, but ones that dry quickly and have a good, non-slip sole.

Although it's well-maintained, this trail is almost never level, and it can get slippery fast when wet. Keep an eye out for wild goats, many native plant species, and of course amazing views out over the water as you hike. Also, keep in mind that if you want to hike all the way to Kalalau Beach (or simply beyond Hanakapi'ai Valley), you need an overnight permit. Hanakapi'ai Beach is the usual turnaround point for day hikers.

This beautiful beach and its black lava caves are accessible only by hiking the famous Kalalau Trail. Swimming is not recommended here: the unprotected waters are subject to strong surf and ferocious rip currents that have killed many visitors. This is a popular stopping/turnaround point for day hikers on the Kalalau Trail. If you want to continue further on the trail, you need an overnight permit. Experienced hikers can also turn inland and hike up the Hanakapi'ai Valley to Hanakapi'ai Falls, although that is a steep, grueling hike with a lot of stream crossings.
