The Warren River is located 10 miles southeast of Providence and 15 miles north of Newport off the Providence River. There are eight marine facilities in the Warren River area, and at least three of them accommodate transients at their docks. Most of the other yards specialize in repairs, but if you run out of luck trying to find a slip, you may be able to find a slip at one of the repair yards.
Use NOAA Chart 13221.
From Rumstick Neck Reach, exit the channel at quick flashing red bell 10, and then set a course for flashing green buoy 1 south of Rumstick Neck at the entrance to the Warren River. From flashing green buoy 1, set a course for, and then follow in green can 3, green can 5, red nun 6,red nun 8, green can 9, red nun 10, and then flashing green 11, which is set on top of Allen Rock (visible in the image above).
From Allen Rock, there is a line of red nun and green can buoy al the way up the river to the twin bridges at Tyler Point. All of the marine facilities are located on the east side of the river below the bridges. Of the eight marinas here, three of them specifically accept transients and the other facilities have repair services on site. There are anchorage areas scattered along the length of the river if you prefer to drop the hook for the evening.
