Great Western 21 day Adventure

[Robyn Edge]

Hi Guys,
Finally found a planning site that is up to my needs, great job..
With my 40th birthday fast approaching (2016) :), my partner and I have decided to plan a great trip to celebrate. Having spent 3 weeks on the west coast before I know roughly where Id like to show my partner. What I'd like to find out is those little gems that are missed of the guides. While we do want to see the amazing natural beauty of inland, we also want to take in the coast as well.

To start he is a map of most of the points we will be visiting

The itinerary so far....
Day 1-2 Phoenix - Grand Canyon (236 mi)
Day 3 Grand Canyon National Park – Lake Powell (324.2 mi)
Day 4 Lake Powell – Bryce Canyon National Park (159.8 mi)
Day 5 Bryce Canyon – Zion National Park – Las Vegas (247.8 mi)
Day 7 Las Vegas - Death Valley (134.7 mi)
Day 8 Death Valley - Yosemite Park (314.1 mi)
Day 10 Yosemite - Lake Tahoe (192.6 mi)
Day 11 Lake Tahoe – San Francisco (184.1 mi)

Will spend 2 full days in San Fran. Still working on the coast leg, but it will be spent on the Pacific Coast Highway (route 1)

Any pointers, links to existing routes and advise always gratefully received guys. It will be a trip of a lifetime and need to get it right.
Thanks
Rob
