The best time to run this trail is typically from late spring through early fall (June to September) when the snow has melted, and the weather is milder. Spring can bring marshy conditions in areas like Big Meadows, and fall offers beautiful foliage. Winter running is possible but requires appropriate gear like snowshoes or microspikes due to harsh conditions and snow.

The trail is unpaved, rugged, and uneven. It begins with a gradual ascent, transitioning to a steady climb through a conifer forest. While much of the path features a mild, undulating slope, be prepared for a significant climb of about 600 feet in the first 1.5 to 2 miles. Sections near Big Meadows can be marshy, especially in spring. You'll also pass through areas impacted by past fires, which can mean unstable ground, dead trees, and less shade.

You'll experience varied scenery, from dense conifer forests to open meadows. Granite Falls, a 50-foot waterfall, is a major highlight. Tonahutu Creek Trail frequently runs alongside the creek, offering picturesque views. Keep an eye out for wildlife, especially in Big Meadows, which is known for moose, elk, and deer, particularly during early mornings or late evenings. You might also spot vibrant wildflowers and views of surrounding peaks.

This trail is generally considered difficult for jogging due to its distance and elevation gain. While the initial climb is the most challenging, the overall length of over 16 km (10 miles) out-and-back to Granite Falls makes it more suitable for experienced runners or families accustomed to longer, more strenuous hikes. The rugged terrain also adds to the difficulty.

Key highlights include the impressive Granite Falls, where water cascades over granite slabs. You'll also pass through Tonahutu Creek Trail and Green Mountain Trailhead. Big Meadows is another significant feature, renowned as the largest montane meadow in Rocky Mountain National Park and a prime location for wildlife viewing.

Yes, this route is part of the prestigious Continental Divide National Scenic Trail (CDT) – Colorado Section and the Continental Divide National Scenic Trail - Rocky Mtn Park. It also utilizes sections of the Tonahutu Creek Trail and the Green Mountain Trail.

Be aware that sections of the trail pass through areas impacted by the Tonahutu Fire (2013) and East Troublesome Fire (2020). This can present hazards such as unstable ground, dead trees, loose rocks, and a lack of shade. Always stay on marked paths and be mindful of your surroundings. Also, sections near Big Meadows can be marshy, especially in spring, so waterproof footwear might be beneficial.

Given the trail's length and difficulty, bring plenty of water, snacks, and appropriate layers of clothing for changing mountain weather. Sun protection (hat, sunscreen) is essential, especially in burn areas with less shade. Sturdy trail running shoes are recommended for the uneven terrain. In winter, snowshoes or microspikes are necessary.
