I sure would like to see the trail lengthened as half of the ride is a combination of fire road and the highway down into Parowan. I can highly recommend both forks of the Bunker Creek trail also. As stated previously, jump off from the top of Brian Head and follow the signs for Dark Hollow. Nice alpine meadows, aspen stands. Nice generally narrow singletrack.
Some areas are quite rocky.
5 of our 10 riders that day got flats. A few minor creek crossings, depending on the time of the year. Mosquitos were out and about early July. The Boy Scout Camp Loop that takes off to the left a mile or two down from the top is quite fun from my recollection 4 years ago, but this time there were signs up proclaiming it was currently closed due to ongoing logging operations. Don't know if that section is toast or not.
