Mount St Helens Nature Walk and Cave Tour from Portland

Enjoy an exciting outdoor adventure on this day trip from Portland to Mount St Helens, one of the Pacific Northwest’s best-known natural wonders. Your expert guide will take you in a cave and lead you on several educational nature walks to discover the unique landscape and abundant wildlife surrounding this active volcano.

When you arrive at Mount St Helens National Volcanic Monument after pickup from your Portland hotel, you’ll get the unique opportunity to go spelunking at Ape Cave, the largest continuous lava tube in the continental US.

Then, explore the visitor centers in and around the 'Blast Zone,' where the volcano erupted. Stopping to take scenic photos along the way, your naturalist guide will describe the impressive ongoing reforestation project and explain how well the surrounding ecosystem is recovering from the volcano’s massive 1980 eruption.

At midday, enjoy a local, organic lunch (see Itinerary section below for a sample menu). Then, head to the Johnston Ridge Observatory, just 5 miles (8 km) from the crater, to enjoy stunning views of the steaming volcano, the growing lava dome and the glacier.

Enjoy a nature walk here with your guide, who'll share the drama of the geological events surrounding the eruption. As you keep your eye out for wildlife, including deer, elk, beavers and birds, learn how volcanoes are monitored and how Mount St Helens has taught scientists new answers to old mysteries!

After your adventure, you'll be driven back to your Portland hotel in the evening.
