Once part of a Naval Base and ammunition storage facility during World War II, the southern end of Prudence Island is now a National Estuarine Research Reserve. The old roads of the former base offer several miles of walking “trails” on the property. For this hike, you will start at the Learning Center. Inside the building are several displays of the type of birds, butterflies, and flowers you may see along the hike. There is also a butterfly garden outside the building. From the Learning Center follow T-Wharf Avenue, just under a mile, south to the wharf itself. The wharf was built by the United States Navy and was quite active during the second world war. Today the wharf is used for recreational purposes. There is an Education Shed at the beginning of the wharf well worth checking out. Follow the wharf to its end for uninterrupted views of Jamestown and the Newport Bridge, but be sure to secure your cell phone. The spaces between the wharfs boards are just wide enough to lose a falling cell phone. Fishing is quite a common site here as well. Several types of birds can be commonly spotted here including seagulls, terns, and cormorants. Returning back to land turn left at the composting toilet (good time for a break if needed), and follow the gravel road (Levesque Memorial Road). It will lead you along an Interpretive Trail that offers an occasional informational board about the surrounding area. This road also offers areas along the left that reach out to the bay for some spectacular views including a memorial park with a picnic area. When you reach Brown Road, stay to the left. The road then starts to bend to the right to another intersection at Albro Farm Road. Stay to the right here and head east following the concrete road. You will start to see several former ammunition bunkers from yesteryear along this stretch. At the end of the road you will come to a Quonset Hut. Here turn left and retrace you steps back to the Learning Center.
NOTE: If you plan on hiking on Prudence Island, be known that the island is not commercialized. There are no restaurants, lodging, or transportation services. There are no public restrooms on the island except a composting toilet by the T-Wharf at the southern end of the island, which is several miles from most hikes. Once you are off the ferry you are on your own. Bring everything you will need for a day hike with no services. Furthermore, ticks are in abundance on the island. It is necessary to take precautions including proper clothing, sprays, and frequent checks.
