The park literature says:

The original 112 acres of  Brinton Brook Sanctuary were deeded to the National Audubon Society in 1957 by Laura Brinton following the desire of her late husband, Willard Brinton and herself to permanently protect their land as a wildlife refuge.  After Laura Brinton's death in 1975, an additional 17 acres were added to the refuge by Mr. Brinton's niece, Ruth Brinton Perera.  

Willard and Laura Brinton found their homesite in the early 1900s by walking from Peekskill and following a topographic map.  When Laura Brinton donated the land to the Audubon Society, she called it a "living museum of this region."  

Saw Mill River Audubon Society sanctuaries are open year-round from dawn until dusk for members and the general public for study and enjoyment. Guided group tours of the sanctuaries are available upon request. Trail maps are available for the six sanctuaries with trails and bird lists and nature trail booklets are available for Brinton Brook.

red trail to right goes to hemlock area

I continue straight; heading northeast on yellow trail

trail markers; take yellow north; lead to a big lake

The Park literature says:

The Pond Loop  -- marked with yellow, leads from the sanctuary entrance and parking lot to Brinton Brook Pond and back again returning on the east side of the parking area.  Along the way, it crosses through a variety of habitats including an old orchard at the intersection with an old farm road, an open meadow that is mowed to keep the forest from intruding, the red maple swamp by the pond, and open stands of both white oak and hemlock trees.

The Back Forty Trail, marked with blue, explores the furthest corners of  the sanctuary with hilly hike through a hardwood forest of black birch, hickory and oak.  It adjoins a Con Edison power line from which you can see the Bear Mountain Bridge.

The Hemlock Springs Trail, marked with red, begins on its southern end in a large hemlock stand and ends near the red maple swamp of Brinton Brook Pond.  Along the way it passes the Split Road Spring designed by Willard Brinton and stone ruins reputed to be those of a farm dating from the Civil War.  The hemlock grove near the spring often harbors wintering saw whet and long eared owls.

The Laurel Rock Trail, also marked with red, is an outer loop of the Hemlock Spring Trail and offers some of the most rugged hiking in the sanctuary with switchbacks across a rocky slope lined with mountain laurel.
