We happened upon Upper Falls as a backup to an original waterfall hike we didn't make it to. Needless to say it was a fantastic option B.
Follow East Canyon Road and take the turn for Bridal Veil Falls. The gate to the larger parking lot was closed when I arrived (January) but there was ample parking just before the gate so we left the truck and started on our way. The first portion of the hike was through some charming day use picnic areas, they are just off the highway, but I bet they get pretty popular in the summer months.
The paved paved followed the Provo River and just half a mile into your walk you will stroll right past Bridal Veil Falls. There was a very muddy, steep, and uninviting looking 'trail' that led from the path straight up to the base of the falls. The view from where we stood was sufficient enough for me and we had our sights set on another muddy, steep trail down the way so we continued on.
The turn for Upper Falls, which is after about a mile, is not marked with a typical trail sign, but rather a landmark. Once you see a small dilapidated building you will veer right off of the pavement onto a narrow trail through gorgeous fir trees. Head upwards for a mile and you are there. That's it! Upper Falls is a super straight forward and incredibly easy* hike that would make for a great place to get out of the car and stretch your legs after a bigger nearby hike or on a drive back to SLC from the desert. I would also recommend this for folks that might not have 6 miles of trail hiking in them but want to see something stunning.
*I had traction shoes for a mid-January hike, without them the mile of trail hiking wouldn't have been quite so easy. If you are doing any hiking in this whacky "winter" Utah is having I highly recommend getting yourself a pair. I wear the FreestepS6 from Hillsound and purchased at REI*
