If you want to ride the gondola and upper tram, you'll need to buy a ticket to Fassa Bike Park.
The singletrack portions of this trail are fun but the extended dirt road bombing in the middle are what give it the lower star-rating. The top of the trail has some technical corners with multiple lines through the root and rock strewn hillside. After you come out of the woods, get ready to pin it down a fireroad for quite a while...hope your brake pads are fresh!
At the bottom, you'll be spat out into the town. Fill your bottles or reservoir using the natural spring (looks like a fountain) on the right-hand side just after you hit pavement. Follow the road down to the main street at the bottom of the valley and turn left to get back to the gondola.
