Get an early start unless your staying at Francie's cabin (then lucky you). This is the approach to Francie's cabin (check out Hutski.com
and the huts.org
for more resources).
Park at the Spruce Creek trailhead and skin up. Start up the Spruce Creek trailhead, you'll come to a Y in the trail. Veer to the left continuing on Spruce Creek trail (taking the the right will put you on the Crystal Creek approach). Continue along Spruce Creek for roughly a 1 mile. There will a sharp switchback heading to the north at this point, this is Crystal Lake road. Take this switchback onto Crystal Creek road and continue up it for a little under 3/4 of a mile. You'll eventually connect with the Crystal Creek basin approach and break out of tree line. Continue on the Crystal Creek basin approach.
