This 148-acre park was named for its abundant mountain laurel, a large forest understory shrub whose showy white flowers bloom mid-June. Laurel Valley is otherwise forested primarily with oak and hickory with small stands of beech, maple and black locust. Lying within the Ronkonkoma moraine, the topography is composed of a series of east-west ravines and ridges that were formed by glacial meltwater about 20,000 years ago. Due to this terrain, trails are moderately difficult with elevations ranging from 45 feet to 230 feet. Trail lengths range from 1.8 miles to 2.5 miles.
