TWIN LAKES
Eastchester, Westchester County, NY


Directions:

From the north, Hutchinson Parkway and get off at Exit 18, turn right and in about .1 of a mile turn left onto California Road; drive .7 miles and park just before Highland Avenue on the right side of the road (just before the no parking sign near the corner of California & Highland).


Geology:

Some huge rock outcrops of mica schist.


Trails:

I was surprised that this area was as rich as it apparently is. (The area needs to be cleaned up a bit as there is the debris that fishermen always seem to leave behind them and the litter of kids hanging out and drinking.)

There is a wide horse trail around the rather large lake partly bordering the Hutchinson Parkway. This is Reservoir No. 3. You walk south east and then quickly a long ways north. You pass a peninsula sticking out into the lake at the base of which the kids obviously hang-out (fire place and lots of broken beer bottles). Then you come to a stream that flows into the lake. At this point the horse trail travels south along the Hutchinson Parkway and then northwest for a short ways back to the start of the walk.

You can extend the walk by taking the pedestrian overpass/underpass crossing that takes you to the east side of Reservoir No.2 of the Twin Lakes Park. The blue trail parallels the lake, then for a while goes farther from the lake. You can make a circular walk by following the shore path when the blue trail goes to the left away from the lake. You will join back up with the blue path when you approach the fence around some kind of business. This reservoir path leads into the Nature Study Woods in the southeastern corner of the area, but that can be visited separately. You can make a figure 8 walk by combining walks around the two lakes.
