Grinnell Creek Trailhead is a trailhead on Grinnell Creek and North Fork Shoshone River in Shoshone National Forest, WY.
This is an unmarked, easy-to-miss trail off the North Fork Highway. Heading towards Yellowstone, park at the gate on the right side of the road immediately after Sleeping Giant Picnic Site (without blocking it). There’s only room for two or three cars. If riding a horse, come from Pahaska Trailhead instead.
