Manuka State Park
Situated in the rugged Kaʻū District on the Big Island of Hawaii, Manukā State Wayside Park (often simply called Manuka State Park) is a peaceful, 13.4-acre oasis that serves as the perfect natural rest stop between Kona and Hawaii Volcanoes National Park. “Manukā,” meaning “blundering” in Hawaiian, originally referred to the ancient land division stretching from the ocean up into the mountains.
Today, visitors pull off Highway 11 to stretch their legs in the incredible 8-acre mid-19th-century arboretum, hike the fascinating transitional forest trails, and enjoy a shaded picnic surrounded by both endemic Hawaiian flora and exotic introduced species.

What to Do at Manukā State Wayside
While frequently treated as a quick rest stop, Manukā actually offers some of the most accessible and educational hiking and botanical viewing on the southwestern side of the Big Island.
The Manukā Nature Trail
The crown jewel of the park is this 2-mile (about 3.2 km) loop trail that takes roughly 2 to 3 hours to complete. Rated as medium difficulty, the path traverses deep transitional forests, skirts ancient lava flows of varying ages, and leads to a lush, forested pit crater. Sturdy hiking shoes are a must due to the uneven, volcanic cobble footing.
Historic Arboretum
Originally established in the mid-19th century, the park’s 8-acre arboretum is a botanical wonderland. It features 48 species of native Hawaiian plants (including Ohia and Koa) thriving alongside over 130 species of exotic plants and flowers introduced from around the globe. Many trees and plants have interpretive markers.
Picnicking & Rest Area
As a designated “Wayside” park, Manukā is specifically designed for stopping and relaxing. You’ll find well-maintained picnic tables and barbecue grills nestled under the dense, shaded canopy of massive trees—the perfect place to eat lunch on a road trip around the southern tip of the island.
Wildlife & Birdwatching
Because the park borders the massive 25,550-acre Manukā Natural Area Reserve, the birdwatching here is spectacular. Early risers can spot native Hawaiian honeycreepers and other forest birds flitting through the dense upper canopy.
Camping at Manukā State Wayside
Unlike many sprawling mainland state parks with massive RV loops, camping at Manukā is a very rugged, stripped-down experience intended strictly for tent camping and backpacking.
| Campground Style | Amenities | Important Restrictions |
|---|---|---|
| Open Shelter Camping | Covered shelters (no sides), nearby restrooms, trash cans | Permit Required. No drinking water available (bring your own). No campfires allowed. |
Pro-Tip: Because there is absolutely no potable drinking water at the park, campers and hikers must bring all the water they will need for their entire stay. The park is highly remote, and emergency services are far away.
Understanding the Manukā Natural Area Reserve
The 13-acre wayside park shouldn’t be confused with the surrounding Manukā Natural Area Reserve, which spans over 25,000 acres. This larger reserve protects incredible pristine ecosystems ranging from subalpine shrublands on the higher slopes of Mauna Loa down to rare lowland mesic forests and coastal environments. The wayside park serves as a safe, designated entry point to view the very edge of this protected natural treasure.
