Closer to the summit, you'll encounter exposed rocky outcrops and stone stairways.

Expect uneven surfaces, and be aware that wet weather can make roots and summit rocks very slick.

The overall experience to the summit is considered moderate to difficult, largely due to the significant elevation gain of approximately 1,000 feet, with most of it occurring closer to the top. While the 'Main Trail' is generally moderate, options like the 'West Slope Trail' and 'Tie Trail' are specifically labeled as difficult due to their steepness and rugged terrain. It's a challenging run for many.

Spring is beautiful with wildflower meadows, including Henderson's fawn lilies. Clear days offer the best panoramic views from the summit. However, the trail can be enjoyed year-round.
