Pebble Creek Trail has easy access from Route 212 just NE of the Pebble Creek Campground in Yellowstone National Park. My family hiked a good part of the trail. The trail isn’t technical; my kids ages 4 and 7 didn’t have any trouble hiking it. We didn’t see any large wildlife, but we did see lots of scat on the trail to indicate multiple species close by. The trail meets the creek from time to time. The water is ice cold but nice for a foot soak. The trail is approximately 109 miles from Powell, WY and I would hike it again.
