Wonderful hike. We hiked about 3 miles in and crossed the stream 12 times - about 1,250' elevation gain. Changing terrain takes you through dark pine forest, amidst bright aspen stands, under fascinating rock cliffs, past a beaver pond, and across open meadows. We met someone who said there are a total of 18 creek crossings if you go all the way to the intersection.

Note that there is now a fairly large parking lot on the left (at about mile 2.4 from Grant). The trail starts across the bridge and heads north. The map the parking lot shows the trail as being east of Guanella Pass Road -- this is inaccurate.
