This trail starts out behind the rock pavillion. It is pretty steep along a wet weather creek. Path is narrow and rocky but very doable. It crosses the hwy at the top and then levels out at the top through the pine before making it's way down the hill (not as steep) to end at the naturalist cabin near the hatchery. The Naturalist was welcoming and showed my young nieces snakes, turtles and fish along with some hides and bones that they kept in the office. If you go left out of the office you can take a short hike along the spring fed lake and hatchery which loops back along the river. I enjoyed this hike with a group of all ages. There is also a trail around the 7 springs that start the current river. And of course an ice cream or meal at the lodge is always welcomed.
