The 5th Annual Lake Hopatcong Block Party will be held on Saturday, May 12, 2018 (rain or shine!) 10 am to 5 pm at Hopatcong State Park.

What is the LHF Block Party?

The Lake Hopatcong Block Party is the largest party around the lake, and this is a cann't miss event for you and your family. The event brings an estimated 3,000+ community visitors together with businesses, non-profit organizations, craft vendors, community groups and food merchants (including our local restaurants). To ensure everyone has fun, there will be a children’s area, varied demonstrations, entertainment, special activities and free boat rides provided by Lake Hopatcong Cruises.


Sponsorships are still available for the 2018 event and offer an array of opportunities for pre-event and day-of-event publicity. See the list of the current Sponsors at the end of this page. While the Vendor's section is sold-out, you have the ability to upgrade to a sponsorship level and take part in the new passport adventure.


A wide variety of artists, crafters, businesses, non-profit organizations, community groups and food merchants have registered for the 5th Annual Lake Hopatcong Block Party.

Volunteers needed

You don’t need to live on the lake to be involved in the lake! We are looking for a big group of volunteers to make the Lake Hopatcong Block Party an amazing kick off to the summer season on the lake.

This is a FUN day, and you get to work with our fabulous volunteer coordinator, Judy Caruso (that’s Judy below in the grey sweatshirt and purple hat)!

New this year…

Visitors are eligible to win great prizes, as they travel through the Block Party on a “Passport Adventure”.  More information coming soon!

We hope you will participate in celebrating Lake Hopatcong and the communities surrounding it!
