Bash Bish Falls State Park is on the Massachusetts-New York border and has sections of the State Park--and eBird hotspots--in both states. Birders who carefully keep bird records by state should be aware of the location of the state line and use the appropriate eBird hotspot when submitting checklists. 

Bash Bish Falls is the highest waterfall in Massachusetts and a popular scenic destination. The dramatic final pitch of Bash Bish Brook drops about 80 feet into an emerald plunge pool. Enjoy a hike to experience the wonder and beauty of this deep, verdant gorge. Nearby, Taconic State Park in New York state offers more visitor amenities, including picnicking, swimming, and camping.

Hiking is required to get to the falls. You have two options:

• From Massachusetts Parking Lot: Difficult ability, about 0.6 miles round-trip. Shorter, more rugged, and strenuous.
• From New York Parking Lot: Moderate ability, about 1.5 miles round-trip. Longer and gradual, but rocky and uneven.

Where you park determines your hike to the falls. Parking is free at the parking lot on Falls Road in Mount Washington, MA, limited to 24 cars. Parking is also available at Taconic State Park, off NY-344 in Copake Falls, NY. On-road parking along Falls Road or NY-344 is not permitted at any time.

Bish Bash Falls State Park is in Mount Washington State Forest.

There are usually portable toilets for Bash Bish Falls on the New York access side, however, they may be seasonal.
