Join DNERR staff and staff from the John Dickinson Plantation for a free boat trip through natural and human history down the St. Jones River.

Historically, the St. Jones River was a major mode of transportation into the city of Dover. While the river has changed over the years, both naturally and by the actions of humans, it remains an important feature of the area.

The boat trips are free. They are appropriate for ages 8 and up. Space is limited. Pre-registration is required.

Boat trips are tide-dependent and will be canceled in the event of inclement weather.

The Visitor Center

The St. Jones Reserve Visitor Center is open to the public and provides hiking trails, hands-on interactive activities and exhibits, restoration demonstration areas as well as a variety of programs and volunteer opportunities for the community, teachers, students, and families. The Center also supports ongoing research and monitoring, field studies, citizen monitoring programs, and training opportunities for coastal decision makers.

Visitors are welcome to tour the St. Jones Reserve Visitor Center (offices, displays and fish tanks) and enjoy the wonders of estuaries through our interpretive exhibits. The Center is open weekdays, during regular state business hours.

The trails are open from dawn to dusk 7 days a week and free of charge. Take note of posted signs during hunting seasons which may result in area closures.


The St. Jones Reserve features a two-mile nature trail, a part of the St. Jones Greenway, with a quarter-mile boardwalk over the salt marsh that connects the Reserve with the adjacent Ted Harvey Wildlife Management Area. Hike the trail to earn activities for your Outdoor Delaware Trail Passport.

The facilities at the St. Jones Reserve are designed with state of the art sustainable infrastructure, including a geothermal heating and cooling system, an on-site wetland based tertiary wastewater treatment system and a photovoltaic (solar panel) system.

The meeting spaces in the St. Jones Reserve are available for rental for educational, governmental, natural resources, and non-profit groups.

The Alvin G. Wilson Conservation Demonstration Area provides a living exhibit where people can see a large variety of conservation practices in action.
