Where are the best swimming holes in the Adirondacks?
The classic Adirondack swimming hole is a cold pool at the base of a waterfall, reached by a short hike, with a granite shelf to lie on. The headliners are Split Rock Falls (Elizabethtown), The Cascades (between Lake Placid and Keene), and The Flume (Wilmington). Season runs late June through August.

The four classics
Split Rock Falls (Elizabethtown) is the most accessible of the set — a roadside pull-off on Route 9 with tiered pools and slabs of bedrock along the Boquet River. It is best late June through August, once spring runoff drops. The eastern Adirondacks make an easy day of it.
The Cascades are twin waterfalls between Lake Placid and Keene — a quick scramble from the road to a deep pool at the base. The rock is slippery; wear sticky-soled shoes.
The Flume (Wilmington) sits on the West Branch of the Ausable — a sequence of plunge pools and bedrock chutes, popular but big enough to absorb a crowd. The water runs cold even in August.
OK Slip Falls (Indian Lake)guards one of the Park's tallest waterfalls at the end of a real hike — the reward-to-effort ratio favors those willing to walk. → all swimming holes & waterfalls in the guide
Prefer sand and a lifeguard?
Swimming holes have no lifeguards and no facilities. If you are swimming with kids, the Park's state campground beaches are the move — staffed in season, with parking and changing rooms — and nearly every major water has one. Browse the lakes atlas or jump to the guide's campground-beach section →
The cold-water reality
Adirondack water is mountain water. Pools that look inviting in July can still shock; read the water before you jump, never dive into a pool you haven't scouted, and treat wet granite as the slip hazard it is. The guide's water-safety section covers the rest, and live DEC alerts flag closures before you drive.
