West Reservoir is a scenic water body located within the Bell's Neck Conservation Area. The reservoir is a popular destination for fishing, kayaking, birdwatching, and hiking. The reservoir was created in the 1800s by damming the Herring River, which flows into Nantucket Sound. The reservoir is part of the Cape Cod Water Protection Collaborative, which aims to improve water quality and protect drinking water sources.

Bells Neck Conservation is 259 acres with a total trail length of 2.75 miles.

In 1668, settler John Bell is believed to have acquired much of this land from the Saquatucket Native Americans. The land passed through multiple owners until nearly 300 years later, the town purchased it to protect the Herring River, West Reservoir, and buffering woodlands. Additional acreage was added over the years. The land surrounds the West Reservoir (freshwater) and East Reservoir (brackish). Trails offer views of wind-ruffled water and sweeping salt marsh. Watch for ospreys and the secretive black-crowned night heron in spring and summer. Each April, herring swim upstream along a herring ladder at the west trailhead. Canoeists and kayakers can launch near each trailhead.
