Spring, summer, and fall are generally the best seasons for this hike. In winter, snow is possible at higher elevations, and the trail can be slippery and muddy after rain, so proper gear is essential. Clear days offer the best views from the summit.
The High School Trail is a gentler start, following an old access road through wetlands and forest. The Section Line Trail is known for its steep ascent, gaining over 2,000 feet in just 1.6 miles, though it's mostly well-graded. The West Tiger 3 Trail is a consistently steep climb on old logging roads, making it wide and generally easy to walk on despite the incline. Sturdy hiking boots with good ankle support are highly recommended.

This specific loop also utilizes sections of the West Tiger 3 Trail, Section Line Trail, and the Poo Poo Point Trail. You might also encounter parts of the Cable Line Trail.
Given the trail's length and elevation gain, it's crucial to bring plenty of water and snacks. Sturdy hiking boots with good ankle support are recommended. Depending on the season, consider layers of clothing, rain gear, and trekking poles for the steep sections. Always carry a map or GPS device, as well as a first-aid kit.
Absolutely! This loop is a popular choice for hikers looking for a significant workout or training for more ambitious climbs like Mount Si or even Mount Rainier, due to its consistent elevation gain and varied terrain.
The steep sections, especially the Section Line Trail, can be challenging. Be prepared for uneven and potentially slippery terrain, particularly after rain or in winter when snow may be present at higher elevations. Always let someone know your hiking plans, and be aware of changing weather conditions. While wildlife sightings are possible, including bears, they are generally shy; know how to react if you encounter one.
