The park’s vastness and variety of attractions can be overwhelming on your own, but by visiting with a guide you don’t miss any of the highlights. Plus, you can learn about the area’s geology, ecology, and history—much of which you might miss if visiting the park on your own.

  • Lunch and headlamps (for exploring the cave) are provided so you don’t have to plan ahead

Total Failure of Tour Guide
, Aug 2022
As much as we were charged for this tour it was not worth for what we paid for. This could have been one of the better tours but our Tour Guide (I will not mention her name-our trip was on July 19,2022). She was uninformative, needs some reading, & re-education. I could be more specific about what questions we asked her but it will take a lot of space. For example: the steps near Spirit Lake, trees, or rocks in the cave but she did not know. She would just stop our bus & not inform us why or where we’re stopping. She was quiet most of the time. When we were at the lava cave some of our head lights would turn off w no back up batteries. She did not have a functioning back up for her own headlamp either. She was unprepared. This was a total disservice to us-tourist.

My apologies, as the guide did not meet our expectations. This is the first complaint we've had about her on this tour, so I'm wondering if this was a sleep issue. I will shadow her and make corrections where necessary.
Unique experience

Lava tube cave, clear day to view Mount St Helen’s. Had sufficient time to climb to observation. The drive was long and winding but worth it. Finished day viewing Horsetail Falls. Lunch was underwhelming but snacks were good.
Great trip, but it is a very long day of driving.

Walking in Ape Cave and getting close to the Summit of Mt. St. Helens we’re both awesome and worth the trip alone. Carrie did a great job of overcoming an early flat tire(although it didn’t seem like she got a lot of support from her boss). Food was average. We compared it less favorably on to the Evergreen Escapes tour we took to Olympic National Park, where there were grilled chicken, beet salad, pasta salad
Full day fantastic experience

Beautiful views. Ape cave was very cool. Carrie our tour guide was very knowledgeable and fun to talk to. We had a great time!
Absolutely Amazing!!

Wow...did this trip a few weeks ago in September 2019 and it was AWESOME. If I could give it 6 stars out of 5 I would. The pre-tour communication was great and pick-up was punctual. Marcus was fantastic and very knowledgeable about the wildlife and geology (I am a geologist and could fact check him on the geology, and he got it right which was impressive!!!). The itinerary was tailored to the weather conditions to get the best out of the day, and there were also some unplanned photo opportunities that Marcus was happy to stop for (the kind of thing you don't get from big bus tours). The tour packed in all the highlights from Johnston Ridge to Ape cave and we saw the mighty Mt St Helens from all was the only tour where you get to experience all of those things in one day. Thank you very much for the day Marcus....I have wanted to see the mountain for many many years as a geologist, and the tour did not disappoint!!

Darren, thank you for the awesome review! It is always a pleasure taking someone out who REALLY appreciates the geology. It was a fantastic day indeed!
Best Tour Ever
, Jul 2019
I would recommend this tour because this tour took us to places we would never have gone on our. Our tour guide was fanominal. He was knowledgeable about the entire Portland area, wildlife, and plant species. When the viability of the mountain was poor he made sure he took us to other places. We went into the lava tubes, walked through forrest, saw waterfalls, and we even saw elk! Overall this tour had everything in one tour!

Lori, thank you for the gracious review! Marcus said you and Phil were good sports about the lack of visibility, and adapted well to the compensatory itinerary. We hope you were able to see the volcano on the drive to Seattle the next day!
