Hidden Valley Preserve

On my first visit I parked at the side south of the bridge and took off down the Orange Square trail along the Shepaug River.  This narrow trail passes the Thoreau Bridge and follows the curve of the river.  It is by far the most popular trail in the preserve and suspect many do it as an out and back easy hike for its beautiful views and fairly easy walking.

To hit the highlights of the preserve I suggest taking the yellow circle trail (off the gardens at the edge of the parking area) and follow the high south bank to the white diamond trail on a steep and somewhat rocky trail.  This will kick off your hike not only with an invigorating climb, but also the great overlook from Hidden Valley’s Pinnacle.

Then head back to way you came connecting down to the yellow circle trail again winding your way to a second lookout.  This one is less spectacular but provides a slightly lower view.  This yellow dot Van Sinderen Trail is named for the family that donated the property and will lead you next to the Quartz Mine.  The mine is another sight to behold with quartz pieces littering the sides of this gully like fallen snow.  There is a large cliff face and overhang with a wall of quartz and off to the left a small cave.

Crawling through the narrow gap enters a chamber with more veins of quartz that was filled with dripping water and ice on my last visit in January 2023.  A very narrow gap in the floor provides an opportunity for further exploration below but I didn’t indulge this time.  From here you can follow the path downhill that was undoubtably built up from the mine down to the river which you can follow back to the soldiers memorial and bridge crossing over to the river to the White Square Baldwin Knoll Trail.

The last leg you can pick to follow the river or over the knoll back to cross the Thoreau Bridge and return to the parking area.
