Travel to Mt. St. Helens and environs with a naturalist guide who will discuss the geology, ecology, climate, history, and legends of the area, as well as the history of US public lands. Your guide will lead you on hikes near waterfalls, through lava tubes, and within oldgrowth forests. Stops both inside and outside of Mt. St. Helens National Volcanic Monument.

Traverse North America's longest continuous lava tube! No matter how hot it is outside, the temperature in the cave is a constant 42F (5.5C), so bring layers. Also, be sure to bring shoes that are suitable for scrambling, and wipe those shoes before entering the bats' home so that they don't get white-nose syndrome!

A lava mold forest. Walk through a wonderland of wells and tunnels, that's hard to pull kids away from.

Weather permitting, we'll take you to the closest viewpoint with a view into the crater that is accessible by vehicle. There you'll have a picnic lunch, and have the opportunity to burn off your lunch by ascending the 357 stairs to a 365-degree view overlooking Spirit Lake, with the mountain looming. If conditions are clear enough, you'll see four stratovolcanoes: St. Helens, Rainier, Adams, and Hood.

The place where Dave Johnston got on the radio and yelled "Vancouver! Vancouver! This is it!", the fateful morning of May 18, 1980.

The visitor center with the most detailed history and geology of Mt. St. Helens.

A fairytale landscape of sapphire waterfalls and blue-grey andesite that were scoured and smoothed by the 1980 lahar resulting from the rapid melting of the Shoestring Glacier by pyroclastic flows.

The visitor center that provides a special retro experience, with a movie about Mt. St. Helens circa 1985, and a 1990s-era Disneyland Haunted Mansion-style park ranger statue, who will give you a lecture.
