Hidden in the southwestern part of the state is Parvin State Park, a park whose history is as varied as its wildlife. Situated on the edge of the Pine Barrens, the park not only has pine forests typical to the area but also a swamp hardwood forest. Spring bursts out in bright colors and rich fragrances with blossoming dogwood, laurel, holly, magnolia, wild azalea and over 200 kinds of flowering plants. Thundergust Lake, Parvin Lake and Muddy Run are popular for fishing and boating. Swimming is allowed in Parvin Lake only.
This park served as home for the Civilian Conservation Corps from 1933 to 1941, a summer camp for the children of displaced Japanese Americans in 1943, a POW camp for German prisoners in 1944 and temporary housing for the Kalmycks who fled their homelands in Eastern Europe in 1952.
