Leave the city before dawn and spend a day walking the blast zone, lakes and hummocks of Mount St. Helens with a local naturalist. This small-group, all-inclusive tour from Seattle mixes geology, wildlife sightings and short hikes with an on-site picnic and park access.
More ways to explore the area's outdoor wonders
Before the highway opens up to the mountain the van feels like a cocoon: coffee steam, maps spread on laps and the soft thrum of tires on wet asphalt. Within two hours the city gives way to Douglas firs and the air sharpens; between the trees the cone of Mount St. Helens appears—a compact, wind-scrubbed mountain that once rewrote the map. On this full-day outing you spend far more time outside the vehicle than inside it: short walks on firm trails, long looks across Coldwater Lake and quiet stops at interpretive overlooks where the crater still steams on warm days.

Fitness Level

Wildlife
History
The catastrophic 1980 eruption blew away the volcano’s north face, reshaped valleys and created new lakes; remaining exhibits and observatories document the event and scientific response.
Conservation
The monument is actively managed for research and restoration—stay on trails, pack out trash, and follow Leave No Trace to protect fragile regrowth on pumice soils.

Layer for variable weather
Temperatures can swing from cool morning fog to brisk winds at overlooks—pack a breathable shell and insulating mid-layer.
Wear sturdy shoes

Layered clothing (base, mid, shell)
Temperature and wind change rapidly near the crater; layers let you adapt without stopping the tour.
