This is our favorite spot to get lobster rolls when we're up in New Hampshire. They have 2 other locations in Portsmouth and Epping but this one is the best because it's right on the beach. Be warned the ice cream portions are absurdly large, trust us get the kiddie.
I wouldn't actually recommend this whole hike because I don't think the payoff view wise is worth it. However, pretty close to the beginning there is a great lookout with a view of Bow Lake. https://www.alltrails.com/trail/us/new-hampshire/parker-mountain-via-spencer-smith-and-neil-mooers-trail
