“Punchy climbs and fun descents is what the Underdown is about.”— Matt Block
Starting from the north trailhead, enter the singletrack on the very west end of the parking lot. You'll be immediately greeted with the punchy climbs and short descents the Underdown is known for. You'll drop onto Loop Road for a hundred yards or so before ducking right into singletrack for more climbing. There are a couple of descents across bridges near some remote lakes before a nice descent into Dog Lake. Take a break by the shelter or keep movin' if the bugs are bad.
More ups and downs await after Dog Lake, eventually descending to the intersection with Old School. Stay left onto Skipping School cutoff for a quicker route to Roundtop climb which of course rewards you with a fun descent and a few boardwalk crossings. Cross the Over/Under bridge and stay right at the intersection with The Hollow. Continue north with more rooty/rocky ups and downs meeting up with Homestead Loop. Stay left for a quick climb then fun fast descent eventually doubling up on a short piece of two track climb.
At the top head straight into the woods for more singletrack switchback descending linking up with an old segment known as the Bumpy Bog. This is not exactly a smooth cruise through the old hemlock stands, but fortunately this is actually one of the flattest sections of the loop.
You'll eventually exit into and opening just off of Loop Road. Head straight north across the opening into the last segment of this loop known as the gravel pit climb. A touch steep at first you'll hammer along the top of the ridge with some sort rooty and rocky ups and downs and a sweet bermed boardwalk descent (very slippery when wet!!). Only a few more roots and rocks and you back home to the parking lot.
