I have used this forum twice before to help me plan 2 amazing roadtrips. One around Arizona and Utah, visiting the Grand Canyon, Monument Valley, the Arches, Zion Canyon, Bryce Canyon, to name just a few places :) Then 2 years ago, travelled around Colorado in an anti clockwise direction starting and finishing in Denver, which was also soon amazing. On both trips trekking where we could and staying in Motels that were available along the way.
We have now decided (at short notice) that this year, in August, we would like to go to the West side, flying in to San Francisco (or Los Angeles) but visiting Yosemite and hopefully going to Yellowstone Park. I am not sure where else will be feasible to do? We have 2 weeks to travel and wanting to visit places to trek, see beautiful sights. I know from past experience that where I may like to plan and what is achievable is often very different, hence a little advice from you guys on the forum (past advice has been invaluable).
Any advice of great places to visit would be much appreciated, again staying at motels that have some space along the way (this allows us to be flexible too)
As we haven't booked flights yet, the destination can be quite flexible, as long we can get back to the UK from a nearby city
