A beautiful cave that continues to evolve and grow, it is not a long tour, but interesting. There are many trails around, including 1/2 mile hike to the canadian border. In addition, there is the Boundary Dam close by and it too is very interesting... I would highly recommend that if you are in the area to do both tours... both beautiful and unique in their own ways.The tours are free, you will need to pay $10 for parking for Gardner Cave or have a Discover pass.

My husband and I hiked to the campground.It was well marked and very clean.we will go back again to camp overnight and walk the two highest trails
