San Rafael - 01. Fuller Bottom to San Rafael Campground (Little Grand Canyon) (UT)
In 2019, several groups mentioned that 275 cfs was plenty of water. Not sure what the minimum is for kayaks, or packrafts.
Take-out at the bridge where San Rafael Bridge Campground, also known as Swinging Bridge Campground is located. This is a good place to camp the night before a trip.
