Old Puna Trail

Overview

This signed Nā Ala Hele route follows a remnant of the historic alanui aupuni (Old Government Road) to Hā‘ena, also called Shipman Beach. Expect an easy‑grade but often very muddy hike through lowland rainforest and over sections of hardened pāhoehoe lava. The out‑and‑back is about 5 miles total and typically takes 2.5–3 hours including time at the beach.

Route and Distance

From the trailhead, the path runs mostly flat toward the coast, entering deep rainforest and, in places, crossing old lava flows. You’ll pass features like a collapsed lava tube and remnants of ancient village sites before reaching the protected sandy cove at Hā‘ena. The trek is out‑and‑back; plan your turnaround so you’re not rushed leaving the beach.

What You’ll See

The mix of rainforest canopy, lava textures, and a rare white‑sand pocket beach keeps the scenery changing. Hā‘ena is shallow (around 3–4 feet in the protected area) and bordered by a lava‑boulder reef. Sea turtles are frequent visitors, and Hawaiian monk seals sometimes haul out—give all wildlife wide space.

Logistics and Access

Trailhead parking is at the end of Beach Road via Kaloli Drive in Hawaiian Paradise Park. There are no facilities along the trail or at the beach, and the beach sits behind private land, so foot access is the only way in. Pack all water and snacks and carry out all trash. Dogs are allowed on leash to protect native wildlife, including nēnē.

Hazards and Etiquette

This trail can be very muddy—even when it hasn’t rained recently—so wear footwear that handles slick conditions. At the beach, the reef and currents make it poor for swimming or snorkeling, and rogue waves are possible. There are no lifeguards. Respect private property, stay on the signed path, and give turtles and monk seals plenty of distance.

Best Time to Hike

Aim for a window that lets you enjoy the cove without rushing; 2.5–3 hours is a workable plan for the 5‑mile round trip plus a short beach break. If avoiding mud is a priority, wait for a drier spell—but know the trail can stay slick regardless.
