Harriman State Park Emerges as a Major Tick-Activity Hotspot
Harriman State Park in New York’s Lower Hudson Valley ranked No. 3 nationally on a World Atlas list of state parks with tick activity and documented tick-borne illnesses, with researchers citing its large deer population and heavy visitor traffic; the report notes rising Lyme disease cases in New York and a 145% jump in ticks submitted for testing from 2024 to 2025, prompting health officials to urge protective clothing, insect repellent, staying on marked trails, and thorough tick checks after outdoor trips.
