Perhaps the most impressive waterfall in the Adirondacks, T Lake Falls requires a 10-mile round-trip hike to reach.
It is the tallest waterfall in the Adirondacks, and one of the highest in New York State, with a drop of 500-600 feet.
NY 8 and NY 10 intersect just south of Piseco Lake. From here, take NY 8 northeast for just over 3 miles before turning left on Old Piseco Road.
After passing Piseco Airport, continue until Haskell Road exits right, then you'll be in the area of the trailhead.
The hike to the falls is difficult, and extreme caution should be exercised.
