Yea, honestly we aren’t sure what mountain chic is either but we needed something other than “whatever” to put on the invite so, “mountain chic” was born :) With that said…Zion in the Fall can be warm during the day, with temperatures around 70-75 degrees high. However, temperatures can drop to the low 40s once the sun goes down. The average is around mid-50s so we would like everyone to pack accordingly! Bring a heavier coat and some light gloves to make sure you stay cozy while staring at the stars, searching for aliens, and roasting a s’more! Please do not bring shoes you are not willing to part ways with! There are gravel trails on the property at AutoCamp & the ceremony and part of the reception area are on grass.
