This little coffee shop closes fairly early — usually around 4pm on weekdays, and 2:30pm on weekends. They have a nice selection of drinks, including a juice bar and a latte that features blue spirulina.

Osborne Pond, also known as Osborn Mill Pond, is a 20-acre lake home to fish species like black crappie and largemouth bass. The Lees Hill Road bridge that goes over Osborn Pond provides a nice view of this waterway, dotted with greenery on the waters surface. Stop on the sidewalk here for a photo opportunity.

September 3, 2024, Great Swamp National Wildlife Refuge
The Great Swamp National Wildlife Refuge in Morris County, New Jersey, is a vital habitat for over 244 bird species and other animals. Established in 1960, it became the first wilderness area within the U.S. Fish and Wildlife Service in 1968. Spanning nearly 7,800 acres, it provides a mix of habitats within the Northeastern coastal forests ecoregion, serving as a crucial stopover for migratory birds along the eastern U.S. The refuge also supports diverse wildlife, including deer, foxes, turtles, and occasional sightings of bears and beavers. The Great Swamp also plays a critical role in flood control and water purification, acting as a natural filter that traps sediments and contaminants while draining the surrounding region and gradually releasing floodwaters during extreme weather.
