# Neshaminy State Park

Neshaminy State Park is a 330-acre (134 ha) Pennsylvania state park in Bensalem Township, Bucks County, Pennsylvania in the United States. Visitors to the park can catch a glimpse of the Philadelphia skyline from a hiking trail on Logan Point. The park is located at the confluence of Neshaminy Creek and the Delaware River. Neshaminy State Park is just off Interstate 95 on Pennsylvania Route 132.

## History

Most of the lands of Neshaminy State Park were donated to the Commonwealth of Pennsylvania by the estate of Robert R. Logan in 1956. Logan was a descendant of James Logan who was the colonial secretary to William Penn the founder of Pennsylvania. Dunks Ferry Road, which forms the western boundary of the park, is one of the oldest roads in Pennsylvania. It was built in 1679 by Dunken Williams to provide access to his ferry which crossed the Delaware River. For forty years, the oral historian Alice of Dunk's Ferry collected tolls from those crossing the river. Dunks Ferry Inn was a major rest stop that served travelers from the mid-18th until the late 19th century.

## Ecology

Neshaminy State Park is 116 miles (187 km) from the Atlantic Ocean, but it is at sea level. This combination of distance and elevation creates an estuary. The tidal effect causes the river to rise and fall each day. The Lenape who once lived on the banks of the river used tides to help them harvest fish. They built low fences in the tidal zone. At high tide the fish would swim in and be caught by the fences when the waters receded at low tide. According to the A. W. Kuchler U.S. potential natural vegetation types outside of the estuary, Neshaminy State Park would have a dominant vegetation type of Appalachian Oak (104) with a dominant vegetation form of Eastern hardwood forest (25).

## Recreation
### The Delaware River

Neshaminy State Park is the home of a 370 slip marina on the Delaware River. Demand for slips in the marina is always very high and the waiting list is long. This is due to the location of the park, it is located squarely within the heart of heavily populated southeastern Pennsylvania. Recreational boating on the Delaware River is especially popular in the summer months. Unlimited horsepower boats are permitted on the river. All boats must display a current registration with any state or have a launch permit from the Pennsylvania Fish and Boat Commission. The Delaware River is a warm water fishery. All fishermen are expected to follow the rules and regulations of the fish commission.

### Swimming

Swimming is not permitted in the river. A swimming pool is open daily from 12:00 pm until 6:00pm weekdays and 12:00 pm until 6:00 pm weekends, Memorial Day weekend through Labor Day weekend. Lifeguards are on duty. Thirteen dollars cash admission is charged to the pool area. For more info, contact http://www.neshaminypool.com.

This tree lined trail is paved and serves as a hiking trail and park service road. River Walk Trail is a loop that begins and ends at Logan Walk. It follows the bank of the Delaware River and passes by the estuary and tidal marsh.
