I am traveling for a week mid-August with my teenagers from Durango to Mesa Verde to Arches to Bryce and then back to Durango. Where is the best place to go out on ATVs or an ATV "safari"? Where is the best rafting and day-hiking? We are going to do the Durango-Silverton Railroad and then we are free agents but we want to have fun and my kids have never been out West.

Has anyone enjoyed the Perseids Meteor Shower in CO/UT?

All advice welcome!!
Thanks!!
