Bucket list destinations, REI style.
REI has a lot of great tours. I've never been on one, because they're out of my budget range, but I have a few friends who have and speak highly. I'm the kind of person that goes to "filters--> strenuous" to find what I'm looking for, but there are incredible options for travelers of all types. Also, it's unclear if these work with my affliate account...but that would be nice. Cheers!
