The Prindle Trail P2 is entirely uphill from the parking lot to the Prindle Institute. P2 can be challenging as, once you start the climb, the gradient doesn't let up much until you reach the top. It connects to the Rim Trail
or the Prindle Trail P1 at the top. You can also break off just before the top (and before you reach the Prindle Institute) to access Woodland Trails W2 and W3.
