Diamond Cove, Maine

Diamond Cove, Maine Maine's premier island resort community. Our community is a small, and friendly one, where neighbors socialize and assist one another. This island is our home.

Diamond Cove epitomizes an idyllic Maine life and makes island living a comfortable reality for a diverse and fortunate few. Our wish is to share this beautiful, historic land with others who are also looking to get away from a fast-paced life and step back into history. Amidst the old army buildings, now restored into inviting homes, Diamond Cove offers residents and their guests an authenticity not easily found.

After having to cancel last year, we're pleased to announce we will host a fireworks only display for the Fourth of July this year. The display will be held on Sunday, July 4, in its usual spot on the Eastern Promenade with the fireworks set to go off around 9:15 PM. A rain date is scheduled for Monday, July 5.

In an effort to not encourage a mass gathering, there will be no musical performance, VIP Area, or ticketed element to this year's celebration, and we will not be providing or managing food vendors as has happened in the past.

Remember - the fireworks can be seen from other locations than the Eastern Promenade. These locations include East End Beach, Fort Allen Park, Amethyst Park, Baxter Boulevard, Payson Park, Martin’s Point on Veranda Street, and Bug Light in South Portland. We're also exploring ways in which the fireworks display can be live-streamed so people can enjoy it remotely.
