Parking availability varies depending on the specific trailhead. For popular spots like Mānoa Falls, designated parking lots are available, often for a fee. It's recommended to arrive early, especially on weekends, as parking can fill up quickly. Some routes, like those starting from Waikīkī or the University of Hawaiʻi at Mānoa, might involve public transport or walking to the trailhead.

Given the tropical environment and potential for muddy trails, sturdy, closed-toe hiking shoes with good grip are essential. Lightweight, breathable clothing is recommended. Bringing plenty of water, insect repellent, and sun protection (hat, sunscreen) is also advisable. A rain jacket might be useful, especially during the wetter months, as showers can occur unexpectedly.
