Sampson State Park sits on land that the U.S. Navy built into its second-largest training base in the country in just 270 days after Pearl Harbor. Named for Rear Admiral William T. Sampson, a Palmyra native and Spanish-American War hero, the base opened in October 1942 and trained 411,429 recruits before the war ended. The Navy chose Seneca Lake specifically because the lake's depth and underground spring system keep it from freezing, making it viable year-round. After the war, the base briefly became Sampson State College, housing returning veterans on the GI Bill, then reopened as an Air Force basic training facility during the Korean War, training an additional 350,000 airmen before closing in 1956. New York State took ownership in 1960, and the park opened in 1963. Today, 38 miles of the original base road network run through the park as hiking and biking trails. The Sampson Military Museum, housed in the original base brig, is run entirely by volunteer veterans and holds artifacts, uniforms, class photo albums, and two naval guns recovered from WWII ships. The park includes 309 campsites, a sandy beach, and a marina with over 100 boat slips on Seneca Lake.
