Remarkably despite it being the 4th of July, getting a late (10am) start and being a beautifully sunny 70° day, I encountered very few people in the park and less than a dozen people after Mount Megunticook.
The trail up Mount Megunticook climbs steadily through the forest until opening up to expansive views, first from Adam's Lookout and then Ocean Lookout. The trail then reenters the woods to the mountain's forested summit.
I continued past the summit to Zeke's Lookout and Cameron Mountain, not seeing another person until reaching the base of Bald Rock Mountain.
Zeke's Lookout is reached via a 0.1 mile steep spur trail. The summit overlooks Bald Rock Mountain.
The Cameron Mountain Trail appears lightly used and infrequently maintained as grass had grown knee high along it in spots until reaching the short spur leading to the mountain's summit. Cameron's summit offers almost 360° views of the surrounding mountains and lakes, and the path to the summit is lined with blueberry bushes.
Bald Rock Mountain was surprisingly empty. I passed two groups on the way to the summit but the summit itself was empty. I descended down the back of the mountain and took the Frohock Mountain Trail to the Ski Shelter Trail on the way back.
