My missus & I did a trip many years ago ('05),we drove from boulder to s.f over 3 weeks, in a rental hatchback & tenting each night.
We basicly rode around 3 hrs each morning, then travelled to the next destination with sightseeing thrown in.sometimes stayed a couple of nights to ride several trails.
we Started at boulder then headed south to crested butte, i had a list of trails to ride but we usually stopped at bike shops to get some info on local rides.
boulder- white ranch, hall ranch.
winter park -lift assist trails.
salida-random trails around the free camping area & monach pass
crested butte-401 trail then some lower trails i can't remember the name of.
Then north to grand junction-lunch loop trails
fruita-kokopelli trails & 18 road(bookcliffs)
moab-slickrock, porcupine rim.
Brian head-some random trails with too many camo wearing hunters looking for something to obliterate.
hurricane& zion N.p-goosberry mesa
vegas-boulder city, bootleg canyon.
It was worthwhile making a few detours to see some of the sights, arches N.P(moab),Zion N.P,grand canyon, death valley, sequoia n.p ,redwoods & yosemite.
There were lots of other spots as well, some were state parks or monuments.
We bought a parks pass at the first one,worked out alot cheaper than paying entry at each of them, some had cheap camping fee's too.
There were plenty of spots we missed, but i don't think trail wise we missed out on too much, they were all unique in their own way & completely different to anything we had ridden before, plus the scenery was generally fantastic and made the rides a whole lot better.
