There's also the option of hiking back up, which I like to due during daylight hours. It might not be as fun at 3:00 AM after a full day of Festival and a few hours of Nightgrass.
It can definitely be done & it's not too bad, about an hour or so ... depending on where you start in Town and end up in the village. Just take the river trail until you're almost directly even with the Shell station & veer to the left on the steeper trail going up. It's a work out, but not too bad. You'll wind up just to the North of the Peaks once you get to the top of the trail.
