FAQs

How much hiking do we do?

This adventure includes 3-4 miles along uneven terrain with some steep inclines and declines with elevation gains & descents. Rated moderate.

Is there elevation gain?

Our tour ranges from sea level to 6,000 feet. During the hike, you can expect approximately 800' to 1,000' elevation gain. While exploring the lava tube, expect to descend and ascend approximately 30-40 feet.

How many different types of volcanic features will I see?

Along the tour, we’ll see a 200-year-old lava flow, spatter cones, fissures, and collapsed pits.

Do we need any special type of equipment to explore the lava tube?

The lava tube we visit is perfect for the casual adventurer. We’ll descend via earthen steps with a rope to assist and there’s enough ambient light to see all of the major features inside the cave.

Is Hualalai Volcano active?

Technically speaking, yes. Hualalai’s last eruption ended in 1801 so it is considered active. However, magma is not close to the surface so we won't see any geothermal activity.
