Planning trip in Beaver Contessa from Tulsa OK to Zion /Bryce and then North to Green River UT and finally into Lake City, CO. We have been to Lake City before, meeting up with friend for the Alpine Loop. We have never been to Zion, thinking to go via Page out of Flagstaff and stay on the east side. Taking 7 yr only granddaughter so have to find parks with pools. Any suggestions or experiences on this route is appreciated.
