The best walks and hikes in KaʻŪ Preserve

Yes, there are several easier options. For a very short coastal walk, consider the Kāwā Bay — Hawaiʻi Island trail, which is just about 1 mile (1.6 km). Another great choice is the Pu‘u o Lokuana Cinder Cone Trail Loop in the neighboring Kahuku Unit of the national park, which offers a fascinating look at volcanic landscapes on a relatively flat 2.7-mile (4.4 km) path.

No permits or fees are required for general public access and hiking in the Kaʻū Forest Reserve. However, the area is rugged and lacks formally maintained trails, so you must be self-sufficient. For official rules and contact information, it's a good idea to check the Department of Land and Natural Resources page for the reserve.

Hiking here is a wild and primitive experience suited for adventurous hikers. The preserve itself does not have officially designated or maintained trails. You'll be navigating through a dense, native forest of koa and ʻōhiʻa trees, often on rugged terrain with steep valleys. It's a place for solitude and a deep connection with nature, not for casual strolls on groomed paths.

Yes, there are some excellent loop trails, primarily in the adjacent Kahuku Unit of Hawaiʻi Volcanoes National Park. The Glover Trail Loop is a moderate hike of about 7.2 miles (11.6 km) that takes you through historic ranching country and past volcanic features.

Access to the Kaʻū Forest Reserve is via public roads like Lorenzo Road, Kiolakaʻa Road, and Mountain House Road. However, be aware that these roads can be rough. Reaching more remote starting points for hikes within the preserve may require a four-wheel-drive vehicle due to the difficult terrain.

The Kaʻū Preserve is a sanctuary for native Hawaiian forest birds. The intact ʻōhiʻa and koa forest provides a critical habitat for rare species. Listen and look for the Hawaiian hawk (ʻio), ʻapapane, ʻiʻiwi, ʻelepaio, and ʻamakihi. The presence of these birds, some of which are endangered, highlights the ecological importance of the area.

While commercial guided tours are not common due to the area's wild nature, The Nature Conservancy, which helps manage the preserve, sometimes hosts volunteer workdays. Participating in one of these events can be a unique way to access and learn about the preserve while contributing to its conservation. Check their Kaʻū Preserve page for potential opportunities.

Self-sufficiency is key. You must bring plenty of water, as there are no facilities. Sturdy hiking boots are essential for the rugged and sometimes muddy terrain. Also pack sun protection (hat, sunscreen), rain gear for sudden showers, a map, and a compass or GPS device, as trails are not marked. Navigation skills are highly recommended.

Kaʻū Preserve offers a primitive, unmanaged hiking experience with no marked trails, ideal for solitude and deep nature immersion. In contrast, the main sections of Hawaiʻi Volcanoes National Park (including the neighboring Kahuku Unit) feature well-defined, maintained trails with signage and facilities. While Kaʻū is about untamed forest, the park offers more accessible trails focused on specific volcanic features like craters and lava flows.

Yes, the area offers several moderate routes for those looking for a longer day out. The Kona Trail Loop is a great example, covering about 7.1 miles (11.5 km) through the varied landscapes of the Kahuku Unit. Hikes within the preserve itself are inherently challenging due to the lack of trails and require excellent navigation skills.

The routes in and around Kaʻū Preserve are very highly rated by the komoot community, earning a perfect 5-star average score. Hikers often praise the incredible solitude and the feeling of being immersed in a pristine, native Hawaiian forest, far from the usual tourist crowds.

Hiking is possible year-round thanks to Hawaiʻi's mild climate. However, the weather can be unpredictable. The dry season, from April to October, generally offers sunnier conditions. The wet season, from November to March, can bring more rain, making the paths muddy and slippery. Always check the local forecast before you go, regardless of the season.
