Mount Battie offers one of the best views of Camden's Harbor. If you just want to see the view, you can drive up the mountain. It costs around $6/person in your car. You can also walk (for free) and take the main road up (it's a little over a mile) or you can take the natural hike up (it's closer to 3 miles). Either the way, the view from the top is definitely worth it :)
Hike one mile (and ascend around 800 feet), to take in some breathtaking views of nearby Megunticook Lake. The entrance to this hike is about a 7 minute drive from Downtown Camden. It is a slightly more difficult hike with streams, slippery spots, and some steep inclines, but it is definitely worth the gorgeous view from the top. If you see a large white cross nestled against a hillside, you're looking up at Maiden Cliff! Be careful walking around the ledges that make up the scenic overlook.
