The detour to the spring adds about 3/4 of a mile and a mild ascent, but it's a pretty spring and some nice views coming back down that you may miss otherwise if you're doing the hike clockwise. Otherwise be sure to look behind you from time to time :) A nice bonus of this hike I found is that you're shielded from the winds (which can be quite strong in the winter) for the better part of the hike. There's a mysterious ruin just off the trail that I'd love to know more about.
