The trail begins at 11,135 feet and climbs through a stark, treeless landscape shaped by recent lava flows and scattered cinder cones. You’ll earn every step on this challenging route, but the reward is a rare perspective of the island’s volcanic heart.
Discover the Wonders of Mauna Loa Observatory Trail
Mauna Loa Observatory Trail offers a blend of volcanic landscapes, scientific intrigue, and sweeping views. Here are some highlights you shouldn’t miss.
Lava Tubes
Lava tubes are natural conduits through which lava once flowed. These underground tunnels offer a glimpse into the volcanic activity that shaped the island.
- Kazumura Cave is not on the Mauna Loa Observatory Trail and is located elsewhere on the island.
- Thurston Lava Tube is not on the Mauna Loa Observatory Trail and is located in a different part of Hawaiʻi Volcanoes National Park.
Scenic Overlooks
The trail offers several scenic overlooks with panoramic views of the island and the Pacific Ocean.
- Pu’u Huluhulu: This cinder cone offers a 360-degree view of Mauna Loa and Mauna Kea. It’s a short hike to the top, but the views are worth every step.
- Mauna Loa Summit: Reaching the summit is a challenging trek, but the reward is a stunning view of the island’s diverse landscapes, from lush forests to barren lava fields.
Unique Flora and Fauna
The trail is home to plants and animals found nowhere else.
- Silversword Plants: These rare plants are found only on the slopes of Mauna Loa and Haleakalā. Their silvery leaves and tall flower stalks make them a striking sight.
- Nēnē Geese: Hawaii’s state bird, the Nēnē, can often be spotted along the trail. These geese are endangered, so seeing one in the wild is a special treat.
Historical Sites
The trail is rich in history, with several sites that offer a glimpse into the island’s past.

- Kīlauea Military Camp: Established in 1916, this camp served as a rest and recreation area for U.S. military personnel. Today, it offers a glimpse into the island’s military history.
Geological Marvels
Mauna Loa’s volcanic activity has created geological features that are worth exploring.
- Devastation Trail: This short trail takes you through an area that was buried by lava during the 1959 Kīlauea Iki eruption. The stark landscape is a powerful reminder of the island’s volcanic origins.
- Halema’uma’u Crater: Located within Kīlauea Caldera, this crater has been active for centuries. The sight of steam rising from the crater is both eerie and awe-inspiring.
Stargazing Spots
Due to its high elevation and minimal light pollution, Mauna Loa Observatory Trail is an excellent location for stargazing.
- Mauna Loa Observatory: This scientific facility is dedicated to monitoring atmospheric conditions. While the observatory itself is not open to the public, the surrounding area offers some of the best stargazing opportunities on the island.
- Mauna Kea Summit is a separate destination and is not accessible from the Mauna Loa Observatory Trail.
