Here's a thought....
We were there last June.
I sometimes camp right in the thick of it but sometimes
like to get away.
Some things to consider.... This is the high country.
It's not that hot most of the time, especially in June.
We felt like we had pretty much seen Mesa Verde in one
full day of touring.
We stayed at a little Colorado state park called
Mancos state park.
Colorado State Park
It was only a couple miles off the beaten path but it
was quiet and scenic and right in the tall Ponderosa pines.
We were there 5 nights because we also drove into
Durango where we rode the famous Durango to Silverton
narrow gauge Steam RR. THAT is awesome!!!
We also rode our motorcycle up the scenic highway to
Telluride and rode the free cable car up over the mountain.
Mancos does not have any hookups but they have water and
a dump station and peace and quiet and great views.
So you have to decide, are you campers or tourists???
In case you're interested, I have a slide show of our
2010 vacations listed in this thread--
KyDan's 2010 slide show
About 2/3 of the way thru are the Mesa Verde pictures
and train ride and Telluride visit and the CG at Mancos SP.
What ever you decide---
