Simply follow the trail. The first 1400 feet of ascent is a steep, but not troublesome, climb along the north side of Tolcate Canyon. After crossing Tolcate Creek, however, the trail steepens considerably. Climb another 2000 feet over merely 1.5 miles to Olympus's South shoulder and take in excellent views to the south and east. Most of the remaining 600 feet to the summit is gained by scrambling over straightforward class 3 terrain. Warning, the smooth quartzite rock that you'll encounter tends to be a bit slick when dry, murderously slippery when wet.

This topographic map nicely illustrates the route. The USGS 7.5-minute quad is named "Sugar House".

PellucidWombat describes an interesting easy 5th class variation that provides an alternative to the "Blister Hill" portion of the Mount Olympus Trail.

Essential Gear

Standard hiking gear. In the late summer months, no water is found along the route. However, as the route is so short (3.5 miles one way to the summit), you needn't worry too much. Rock shoes are unnecessary, though your footwear should grip well and have enough stability for the punishing, rocky descent.
