Explore Mt. St. Helens on a flexible Seattle day trip with guided hikes, park highlights, a seasonal picnic lunch, and a small group.

About this tour

Trade the city streets of Seattle for the dramatic landscapes of Mt. St. Helens National Monument on a full-day small-group adventure. With a local naturalist guide, explore the mountain’s changing terrain on foot and take in panoramic views of the blast-swept landscape from the Eruption Trail.

The itinerary is shaped by the season and park conditions, with possible stops at Coldwater Lake or the Hummocks Trail. Keep an eye out for Roosevelt elk, and enjoy guided walks tailored to your group’s interests rather than spending the day only inside the vehicle. A seasonal local lunch is served picnic-style outdoors when conditions allow, alongside coffee, tea, snacks, and water. Transportation, park entrance fees, and Seattle-area pickup and drop-off are included; pickups near SeaTac Airport or Tacoma can be requested.

Mt. St. Helens National Monument rewards curious travelers with striking scenery and a powerful sense of place. Join this Seattle Mt. St. Helens National Monument tour for a flexible day of fresh air, local insight, and memorable views.

How this score is calculated

This score is based on one provider. Viator rates it 4.88 from 137 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Seattle
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 7.8. Top 16% in Seattle means it ranks in the top 16% of tours in Seattle by this score.
