Just hiked this one yesterday. Fairly steep most of the way up. Some lower sections have downed trees that haven't been cleared yet, but it isn't too difficult to get around them. A lot of wild iris blooming right now all along the route. The whole time you are under the forest canopy so there is no view, but on a warm day I would prefer the shade anyway. Rather than go back down, we went for 1.4 miles east on the Northside Trail and then back down to the lake on an unnamed trail, which can be found near the junction with Eldridge Grade. I wouldn't advise going down the unnamed trail if you are tired or don't have good soles for traction, as it was extremely steep in some areas with a lot of loose rock. Also a bit overgrown near the top with a lot of poison oak hanging out into the trail. Thought it would be better to loop around, but next time I'll either go out to Eldridge and back down that way, or else just go back down Collier Trail to the start point at Lagunitas Lake.

This trail starts out gently but after a half mile gets steeper and then quite steep in places, but well maintained. It eventually levels off some and gets to the protected top of the mountain, where there are BIG old growth redwoods around Collier Spring and Northside trail to the north. After the springs, which are not advertised as potable (but I have) you can climb another 400 feet and half mile not quite as steep to Ridgecrest for a great view. I prefer returning by other trails to make a loop and avoid the slippery gravel sections of Collier Springs, which could be dangerous if in a hurry. After rains this can be a wonderful, noisy little cataract trail for sections, although you may have a tricky ford at the bottom. This is one of my most favorite trails for cardio, as you can just walk fast once it gets steep and have a no impact workout.
