Lava Tube at Hawaii Volcanoes | Kailua Kona

The Lava Tube at Hawaii Volcanoes is a subterranean geological formation located on the island of Hawaii, within Hawaii Volcanoes National Park.

This natural tunnel was created by flowing lava.

Visual Characteristics

The interior of the lava tube is characterized by rough, solidified basalt rock. The walls are dark gray to black, with occasional reddish-brown oxidation. The tube's diameter varies, typically ranging from 1.5 to 15 meters. The ceiling height also fluctuates, with some sections allowing standing room and others requiring crouching. The floor is uneven, composed of loose volcanic rock and solidified lava flows.

Location & Access Logistics

The Lava Tube is situated approximately 40 kilometers southeast of Kailua Kona. Access is via Highway 11, turning onto Crater Rim Drive within Hawaii Volcanoes National Park. The specific entrance is marked by a small, paved parking area adjacent to the highway. No public transport services operate directly to the site. Parking is limited to approximately 10 vehicles.

Historical & Ecological Origin

This lava tube is a result of volcanic activity from Kīlauea volcano. It formed when a pahoehoe lava flow advanced, and the outer surface cooled and solidified while the molten lava beneath continued to flow. Once the lava drained away, it left behind a hollow tube. This geological feature is classified as a lava tube, a specific type of volcanic landform.

Key Highlights & Activities

Exploration of the lava tube is the primary activity. Visitors can walk through the accessible sections of the tube. Flashlights or headlamps are required for navigation due to the absence of natural light. The temperature inside the tube remains consistently cool, around 13-16 degrees Celsius.

Infrastructure & Amenities

There are no restrooms or food vendors directly at the Lava Tube site. Basic signage indicating the entrance is present. Cell phone signal is intermittent to non-existent within the tube and surrounding park areas. Limited shade is available at the entrance area.

Best Time to Visit

The best time of day for visiting is during daylight hours for safe navigation. The months of April through October generally offer drier weather conditions. There are no tidal considerations for this inland geological feature.

Facts & Legends

A unique aspect of this lava tube is its use as a shelter by Hawaiian royalty in ancient times. It provided a cool refuge from the sun and a secure location. The solidified lava formations within the tube can sometimes resemble melted wax or other organic shapes.
