I visited Acadia National Park in Maine many years ago with my family, and after returning recently it's still just as magical as when I first saw it. Acadia boasts a stunning, wild landscape, beautiful vistas and all the lobster you can eat (seriously). It's a great destination all summer long and well into the fall, when the weather is cool and refreshing.
In addition to watching the sunrise from the summit of Cadillac Mountain, exploring the Park Loop Road, and stopping for lunch at Jordan Pond House (a quintessential Acadia itinerary), we made our way to Schoodic Peninsula at my parents' recommendation. The entire park is breathtaking, but there's something really special about experiencing the stillness and solitude that's available on Schoodic Peninsula. You feel as if you have the entire park to yourself.
We stayed in Bar Harbor, and on our next trip I'd love to explore Northeast Harbor. Side Street Cafe has outdoor seating and does a great happy hour and has outdoor seating. Blaze serves up craft beers and has a wood-fired oven, which they put to good use. Their wood-fired lobster was incredible, and the space was warm and cozy on a crisp night.

Yes, you can get lobster on everything, including Cobb salad and quesadillas
