Exploring the Lava Tubes of Bend, Oregon

Did you know Oregon has 1000-year-old lava tubes that you can explore near Bend?

When visiting the area of Smith Rock in Central Oregon, most itineraries include rock climbing, horseback riding, a ranch visit and several hikes, but did you know there is a fascinating system underground too?

Boyd Lava Tube

Deschutes County encompassing the cities of Bend, Sisters, and Redmond (our 3 stops on our Oregon adventure) houses 1000 lava tubes created by volcanic activity thousands of years ago.

The exit to the cave

We met up with our guide Nick of Wanderlust Tours in the town of Bend.

Our directions stated “in the Fred Meyer parking lot” I guess Fred Meyer is a big chain of stores, but Dave and I had the hardest time finding it. We were like, “Maybe Fred Meyer is the mayor of the town and it's in the main square.

Eventually, we stumbled across a big parking lot housing a big “Fred Meyer” sign and turned in. Sure enough, Wanderlust Tours is located right inside. Ha, it's an adventure wherever we go

Tour of the Lava Tubes

The drive to the Boyd Lava Tube was about 20 minutes.

Nick told us about the history and geology of the area during the ride.

Going Underground

It was a windy day and as we got out of the van, we were thankful we were going underground.

60 feet underground to be exact.

We walked down a set of metal stairs and began the tour. Dave stayed behind to grab some photographs while I listened to Nick tell us the history.

That's how things usually go on our tours, Dave wanders off to take his incredible photographs and I stay close taking notes on my iPhone while everyone else in the group thinks I'm busy browsing Facebook or something.

Bats of the Lava Tubes

There are 1000 lava tubes in the area and most of them house hibernating bats in the winter. They are not open to the public. 

The Boyd Lava Cave has only one very narrow opening making entry and exit difficult for bats.

That's a good thing for tours as it is the only cave still open to the public so as not to disturb the bats.

Bat Hibernation Lesson and the Lava Caves

Nick explained to us that bats are true hibernating animals, unlike bears.

Bears eat a lot of food, store their fat and simply sleep in the winter.

Bats, don't stock up on food, instead they slow down their metabolisms, drop their heart rates and lower their body temperature.

It would be very dangerous to wake them in the middle of hibernation because they would need to immediately look for food and there aren't any insects around in the middle of winter.

So the lava tubes that bats frequent are closed to the public.

Dark corners are a perfect place for a bat to hibernate.

Be Prepared for Darkness

When exploring Boyd Cave, be sure to take extra batteries and more than one headlamp.

There are no other light sources besides the entrance and the cave runs 1800 feet (600 metres) long. Within minutes we were in complete darkness.

Have you ever been in the dark where absolutely no light can enter? It's a creepy feeling to not be able to even see the slightest shadow.

At one point during our tour, Nick had us all turn our headlamps off to experience it.

It was only a few seconds before someone turned their headlamp back on. I am assuming because they were a little freaked out.

The Feeling of Pure Darkness

I remember eating at O Noir in Toronto a few years ago.

It is a dark dining experience to help customers understand what life is like for the visually impaired. Visually impaired servers also work there.

It took me a while to get over the anxiety of being in complete darkness.

Even though it was already black inside, I kept my eyes squeezed shut through the entire experience because when I opened them and saw nothing, but grew anxious.

I'm sure that person was experiencing what I felt during my dining adventure.

This is what you see in pitch darkness – nothing

The tour lasted about an hour and a half where we crawled through thin cracks, over rock rubble and on smooth paths.

How Were the Lava Tubes Made?

The tubes were made from an eruption 150,000 years ago. It was the first large eruption causing giant lava rivers flowing through the valley.

Over the next tens of thousands of years, smaller eruptions occurred creating smaller rivers.

There was a little trench in the side of the huge cave that was caused by one of the later eruptions.

It looked like a little ditch on the side of the road.

We walked right to the end of the line.

Nick told us that not everyone makes it, but I have a feeling he was just being nice.

It wasn't that difficult at all and we've been through plenty of narrower passages.

For the most part, the lava tube is very wide and spacious with just a few small squeezes and one final crawl space where you have to get down on your hands and knees.

 It is a very short crawl, so you won't feel any anxiety.

We had a tour of all ages.

A three-generation family was on tour with us, and the grandmother was crawling through with as much gusto as her grandkids.

So don't be afraid, the Lava Tube tour is fascinating, fun, and one of the most unique experiences you'll have in Oregon.

Tips for the Lava Tube tour

  • Bring a jacket, it can be cold down there
  • Wear clothes that you are willing to get dirty – it's dusty
  • Wanderlust Tours supplies headlamps and batteries including helmets
  • If you are exploring on your own (which you shouldn't be because Wanderlust Tours has permits and others in the caves are exploring illegally) make sure to bring an extra headlamp or flashlight with extra batteries. You don't want to be trying to make your way back in the dark.
  • Be prepared to crawl around a bit and to scramble over rocks
  • Enjoy!

Our Tour was provided by Wanderlust Tours. TripAdvisor's number one rated tour company in Bend.

We understand why these guides are passionate about their jobs! I have never had a guide make rock history so much fun.

Nick loved talking about the different types of lava flows.

He spoke with passion about how the fan-like flow known as “pahoehoe flow” is different from a flow leaving behind clumpy rock formations known as “aa.”

Yes, I learned a lot that day and retained it. You know why? Because it was fun!

And if you go on a Lava Tube Tour You'll have fun too!
