Pu'u Hapapa Summit Trail

Access to this trail is highly restricted as it is located on Schofield Barracks, an active military installation. Typically, you'll need a Department of Defense ID card or a visitor pass. The trail is usually open only on select weekends, and these dates are often announced just 1-2 weeks in advance. It's crucial to check the current status before planning your visit.

Due to its location within a military installation and the Honouliuli Preserve, access is restricted and often requires specific authorization rather than a general permit or fee. As mentioned, a Department of Defense ID or visitor pass is typically needed. There are no general entrance fees for the preserve itself for this trail, but you must adhere to the military base's access rules.

The hike often begins at the Kolekole Trail Trailhead. This area itself offers a beautiful lookout. Parking availability is subject to the military installation's regulations on open weekends, so specific parking instructions should be confirmed closer to your hiking date.

The terrain is challenging and varied. It starts gradually, but quickly becomes intense with steep slopes, rock scrambling, and narrow ridges. You'll encounter two 'notches' that require scrambling up and down, offering good handholds but still demanding. Sections can be overgrown, scratchy, and involve navigating tree roots and steep dirt drop-offs. The Waiʻanae Summit Trail (WST) side, part of the loop, is comparable to a moderately challenging Class 3 climb due to exposure and climbing on loose volcanic basalt.

No, this trail is classified as intermediate to difficult and is generally not suitable for children or pets beyond the initial Kolekole Trail portion. The steep inclines, rock scrambling, and narrow ridges require a good level of fitness and experience.

Given the challenging terrain and potential for extreme winds, it's best to hike during drier, cooler months if possible, though specific 'best' times are less relevant than the trail's limited access. Always check weather conditions immediately before your planned hike, as extreme winds can make it dangerous.

No, due to its challenging nature, restricted access on a military installation, and classification as intermediate to difficult, this trail is generally not suitable for pets beyond the initial Kolekole Trail portion. It's best to leave your furry friends at home for this adventure.

Be prepared for significant rock scrambling, especially through the two 'notches.' While not free climbing, good handholds are available. The Waiʻanae Summit Trail (WST) side involves climbing on loose volcanic basalt, so careful foot placement is essential. Always assess your capabilities, wear proper footwear with good grip, and consider bringing gloves for scrambling. Extreme winds can be dangerous, so check conditions beforehand.

Given the trail's difficulty and exposure, bring plenty of water (more than you think you'll need), sturdy hiking boots with good ankle support, sun protection (hat, sunscreen, sunglasses), and layers of clothing. Gloves can be helpful for the rock scrambling sections. A first-aid kit, navigation tools, and snacks are also highly recommended.
