X2 on Kavoom suggetions. We have been going to this corner of Ut, Co, AZ and NM for years and always find something interesting. We were at the North Rim last year in mid Sept but stayed at the lodge--left the RV hooked up in Kabab. It snowed and was really crisp clear weather. We have also done the South Rim in Sept and really enjoyed the Ranger led programs. Included in our GC adventures was a 6 day float trip thru the GC--a truly unbelievable experience in 2016. Blanding is also interesting lots of history of the region. I suggest Antelope Canyon tours near Page--great slot canyons.
