One of the lake's best days!  The Lake Hopatcong Block Party celebrates all facets of Lake Hopatcong life by bringing visitors together with businesses, non-profit organizations, community groups, crafters, and food vendors for a community day like no other featuring activities, raffles, giveaways, a children’s scavenger hunt, and more.

An amazing day at the lake that has grown incredibly over the years and raises a huge amount of money for children in need. Party follows at the Elks at 2:00pm - see their website for ticketing information.

Lake Loop is the Lake Hopatcong Foundation's annual bike, hike, paddle fundraiser. Participants can choose their challenge to get moving, have fun, and raise funds to support a healthy community and a healthy Lake Hopatcong.
