The New Jersey Lighthouse Challenge® is a not-for-profit event presented by The New Jersey Lighthouse Society, Inc. for the purpose of raising public awareness of lighthouses in general and New Jersey’s lighthouses, specifically. It is a rain or shine, two-day event held during the 3rd weekend in October when 11 land-based lighthouses are open for visitation and climbing. During this weekend, the public is invited to visit any or all of the sites along the Challenge route.
At each site visited, participants of the Challenge receive a complimentary souvenir depicting that particular lighthouse. Collect all 13 and you will receive a complimentary "completion" souvenir at your final stop to commemorate your achievement.
