Our weather, 21 miles from Zion has been in the mid to upper 80s and forecast to remain there for the next couple weeks. This is NOT the off season in Zion, but is the PEAK of the fall tourist season, so plan accordingly. Bryce is much higher and will be a little cooler. However it is also peak tourist season there. Should have no problem with RV space during the week, but weekends will be a problem at both areas. This weekend is Octoberfest in Springdale, just outside Zion and we are going tonight. There will be various festivals into mid Nov in the Zion area and through the month in Bryce City.
