North Fork Trinity River to Grizzly Lake

North Fork Trinity River to Grizzly Lake Professional Guide

Detailed Trail Description from our Guidebook

"The trail starts out easy, climbing only 1000 feet within the first 10 miles of excellent tread in lush, deep canyons that follows the course of North Fork Trinity River and Grizzly Creek. You will see an amazing variety of trees, ferns, and flowers along the way and maybe even a school or two of big steelhead or salmon.

Picturesque old cabins on benches along the river and a plethora of relics along the way hearken back to the heyday of the old mining period. Don’t expect to be alone at Grizzly Lake or Grizzly Meadows—the drama of Grizzly Falls and the stunning beauty of Grizzly Lake and Thompson Peak lure many admirers. However, one of the advantages of the longer route described here is that you’ll more than likely have the first 13.5 miles of trail substantially to yourself."

"Starting at an elevation near 3000 feet, with the possibility of reaching 9002 feet on top of Thompson Peak, the Trinity Alps highest summit, this route exposes visitors to the diversity for which the area is renowned. For the first 10 miles the elevation gain is a paltry 1000 feet, as the trail follows the gentle route of the North Fork Trinity River and lower Grizzly Creek through a wide range of trees, ferns, and flowers. Along the way are a number of old cabins and plenty of leftover relics from the mining days. The last 7.5 miles gain nearly 6000 feet, passing through mixed conifer and red fir forests, and mountain meadows on the way to extraordinarily scenic, subalpine Grizzly Lake nestled into a granite cirque below jagged Thompson Peak."

The fire that burned through this area, burned quite a bit of the lower trail up to Grizzly Meadows. In some places this just meant that the ground was free from debris and the very bottoms of the trees were blackened, in other places it's so burned out that camping there is an ashy, and sometimes eerie, affair (although still entireley great, you're camping, right?). The majority of the first 15 miles are burned to some extent, though all of the cabins, mining ruins, etc, still look great. This trail was probably amazing before the fire; it's still very nice hiking, and will again be great in a few years. The trail description is correct, the hike in is very nice, and eveything with Grizzly in the name lives up to its reputation. Many people came in through the newer trail, which is another option.
