A short and secluded walk along Fifteenmile creek offers views of waterfalls, cliffs and old coal mines.

Finding this trail is half the fun and when you do you'll most likely have it to yourself. It's surprising to find such a vigorous creek on Tiger Mountain, which at one point bounces along a rocky bed in a way that might interest kayakers. The trail is easy to follow and deadends deep in the recesses of the "Grand Canyon".

Using an unofficial boot trail at the end it's possible to connect up to the Hobart-Middle Tiger RR grade, but bring boots because this is usually a muddy project.

Getting There

Access to this trail is complicated by the absence of legal parking spots near the trailhead. One option is to park near the Mirrormont fire station and walk approximately a half mile north to the connector trail between the road and the actual trailhead inside the park.
