My boyfriend and I are looking to do a road trip national parks tour from the 3rd week of June until the first week of August, starting and ending in Austin, TX. I've camped a lot and we've been to a bunch of national parks already, but I was wondering if anyone had any good ideas for routes we should take- texas is way out there! We would love to hit Arizona, Nevada, CA, Utah, Washington, MT, Wyoming. We just have to be in Denver on August 2nd at the end of the vacation and then back to Austin. Any pointers would be greatly appreciated too. We're looking to rent/buy a conversion van or something similar.
