The most common access point for this loop is via the West Tiger Mountain #3 trailhead. There is typically a designated parking area at the trailhead. Be sure to check for any specific parking regulations or fees for the Tradition Plateau Natural Resources Conservation Area before your visit.
The Talus Rocks Running loop is located within the Tradition Plateau Natural Resources Conservation Area. While there are generally no specific entrance fees for the conservation area itself, you may need a Discover Pass for parking at certain trailheads in Washington State Parks and Recreation Commission lands. It's always best to check the latest requirements before you go.
Yes, the Talus Rocks Running loop is generally dog-friendly. However, dogs must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all trail users. Please remember to pack out all pet waste.
The loop offers a great experience year-round, but conditions vary. Spring and fall provide lush scenery and comfortable temperatures. During winter, expect potentially muddy, rooty, and slippery sections due to wet leaves and rain. Summer can be warm, but the old-growth forest provides good shade. For the most picturesque experience with waterfalls running full, visit after significant rainfall.
The terrain is quite varied. You'll encounter wide, flat sections, especially at the start, transitioning to narrower, more primitive paths. Expect challenging ascents and descents, some of which are steep and can be muddy. The path is often rooty and uneven, particularly near the Talus Rocks, where it winds around large boulders. Good traction footwear is highly recommended.
The primary highlight is the unique geological formation of the Talus Rocks themselves – giant, moss-covered boulders forming small caves and canyons. You'll also pass by an Abandoned School Bus on Tradition Plateau, and enjoy lush old-growth forest, abundant ferns, and several waterfalls that create a beautiful, foggy atmosphere when running full.
For jogging, the loop typically takes around 50 minutes to an hour to complete, depending on your pace and how often you stop to enjoy the scenery. The tour data suggests an average duration of 51 minutes for this 5.95 km (3.7 mile) route.
While generally rated moderate, this loop presents a good challenge for runners. It features significant elevation gain (243 meters / 800 feet) over its distance, with immediate and intense inclines in some sections. Beginners with a good base level of fitness might find it manageable, but those new to trail running should be prepared for steep, rocky, and potentially muddy terrain. It's a rewarding route, but not entirely easy.
Yes, this loop utilizes and connects to several other popular trails within Tiger Mountain State Forest. You'll run on sections of the West Tiger 3 Trail, Bus Trail, Section Line Trail, Around the Lake Trail, and Nook Trail, offering opportunities to extend or vary your route.
Yes, despite being primarily a forest run, certain sections of the trail offer outstanding views, reminiscent of those found at the summit of nearby Mount Si. Keep an eye out for openings in the trees, especially on higher sections, to catch glimpses of the surrounding landscape.
Given the varied and sometimes challenging terrain, we recommend wearing trail running shoes with good traction. Bring sufficient water, especially on warmer days, as there is no water available on the trail. A small first-aid kit, navigation (like the komoot app), and layers of clothing are also advisable, as weather can change quickly in the forest.
