While this trail can be ridden in either direction, starting from Aerie Drive offers longer descents and more cross-mountain riding. Parking is available on either end, but access from the rail trail requires parking near White Pine Touring. Once finished you can take the bus back to your car on Aerie Drive, or bike back. While this trail is easily accessed without a shuttle, having access to one cuts down the time enough to make it a great lunch break ride.
Throughout the ride there are great views of Park City proper, as well as the surrounding mountains and ski resorts. During the descent there are a few rocks and roots, but otherwise Lost Prospector is a very smooth trail, great for fast descents and carving through corners.
When riding the trail from the Rail Trail
entrance, the climb is significantly longer, but features a more technical descent with looser dirt and rockier sections of trail. Accessing Lost Prospector this way provides a more rigorous workout, and definitely pays off with a more challenging descent.
All in all, Lost Prospector is a great short trail, providing fast descents and rigorous climbs depending on the rider's mood. With connections to many other trails in the area, it's very easy to mix in different sections of trail to your regular ride.
