From the parking lot we went right and followed the arrows and white blazes to the yellow to green to blue. The remains of the Cornish estate are at the very end of the trail, about a quarter mile away from the parking lot! But we were happy we hiked up for the views and the time spent alongside the waterfall. We thought we had somehow missed the old mansion! So I thought I’d let anyone else know; it’s at the end of the trail. But do what we did and go right at the trailhead! It’s so worth the views and feeling of accomplishment and the estate is like icing on the cake at the end of the hike! Enjoy!
