Most of the climb to the summit of Tiger 3 (T-3 for short) follows an old logging roadbed. Consequently, the run climbs at a steady grade, gaining about 2,000 vertical feet over the course of three miles.

Almost the entire climb takes place under the deep forest canopy, with green ferns and dense undergrowth creating a middle-of-nowhere feel, even though you’re just minutes from the city. Once you reach the summit, the view opens up in front of you to reveal the stunning mountain peaks in the distance.

The trail to the summit is well-signed, but be aware that there are several trails beginning at this parking lot. The various trails head off in different directions—they don't all lead to the summit of T-3. However, these other trails provide options to turn T-3 into a longer run… such as the loop mapped here. If you don't want to turn this run into a loop, then simply return to the car on the trail you ascended.
