The New Hampshire Coastal Cleanup is held in September and October in conjunction with the Ocean Conservancy's International Coastal Cleanup (ICC). New Hampshire has participated in the ICC for over 30 years. This is the largest one-day volunteer event of its kind! During the cleanup, you'll pick up litter to beautify the coast and protect marine life, while also recording your findings so that we can use the data to prevent pollution in the future. All supplies are provided. Cleanups typically last 1-2 hours. Please arrive on time as we will begin promptly.
