Best Time to Camp at Millersylvania State Park

Summer visitors will appreciate the natural shade that keeps the camping areas refreshingly cool when temperatures rise elsewhere. The park truly comes alive during holiday weekends like Memorial Day, when families flock to the lake for celebration and recreation—expect a bustling, social atmosphere during these peak times. Keep in mind that late summer occasionally brings wildfire smoke from the wider region, which can affect air quality and visibility during your visit.
