This trail stretches from up Provo Canyon, just a little ways past Bridal Veil Falls at Vivian Park, all the way to Utah Lake, covering about 14 miles. It is a paved trail, relatively flat, and highly populated for most of the year.
It made for fun dates for Mallorie and I to do while we were engaged, and where it was so close, it didn't require that we had huge amounts of time to have to go grab a few minutes of riding.
