This is a bucket list adventure – a hike into the crater of an active volcano! With a professional geologist to explain the creation of the domes and canyons, pumice fields and lava beds, we will travel across the Pumice Plain to the Goat Rocks Fan and then high up into the crater breach to the snout of Crater Glacier. This is as close as you can get! Plus, there are astounding views of Mt. Rainier, Mt. Adams, and Spirit Lake! The trips begins Friday at the Mount St. Helens Field Camp where we will treat you to an amazing dinner, followed by a fireside lecture by the geologist. Guests are welcome to stay Saturday evening as well for dinner and another night’s rest in the shadow of the volcano.


Hike Description: This hike into the crater begins the night before we hit the trail at our Ridge Camp where we will serve you dinner, enjoy the campfire, and talk about the history and geology of the mountain. After a good night’s rest, we will have an early morning wake up and breakfast at 5:00 a.m. We will depart camp at 6:00 and drive a short distance to the trailhead. The hike begins on trail, as we descend from Windy Ridge and cross the Pumice Plain. We will depart the Loowit Trail and continue off trail as we travel up toward the crater breach. At stops along the route you will hear about the geology and ecology of this amazing landscape. We will also cross two unbridged and dynamic streams. At the crater breach, we will discuss Crater Glacier and other fascinating facts about Mount St. Helens unique landscape. We will then loop back to the trailhead via a different route. The ascent and descent involve navigating relatively step and loose grades; therefore, this hike is not for the faint of heart but is well worth the immense views. We expect to be back to the trailhead no later than 5:00 pm. When we return to camp, we will make dinner and you are invited to spend the night again. We will have a campfire and relax after our hike that night and have breakfast in the morning.
