This hike is for you if: You want to check out an awesome cave that seems like it belongs somewhere way more exotic than Dover Plains.

A nature preserve whose highlight is a stunning rock formation and waterfall in a cave. It was used by Native Americans as a hideout in the 17th century, and then for weddings in the 19th century.

Dover Stone Church's highlight is a metamorphic rock cavern in the shape of a church’s cathedral window with a cascading waterfall through the cave’s interior. The Stone Church Brook, a tributary of the Ten Mile River, flows through and out the cavern entrance.

Referred to as "Miracle at Dover Stone Church". The stone church is a natural formation and said to have been a refuge of Pequot chief Sassacus. It is a large cave with a waterfall inside that leads to a mossy brook. At certain times when the weather is cool and the sun is bright, one can see shafts of light coming in from outside.

A great spot for photographers to capture the hues of rainbows streaming through the cave. Wintertime is equally spectacular, with ice formations changing hues in the light. Quite spectacular.

This is one of the participating locations on the Dutchess Tourism Zen Finder Outdoor Experience Trail, a free digital passport featuring some of the best hidden-gem trails, fresh-air activities and captivating views in a curated itinerary of outdoor highlights.

And only a 15-minute drive from the Millbrook "Air" Bnb.
