Jerimoth Hill is the highest point in Rhode Island. It is hardly a mountain, but is of interest to Highpointers.
Jerimoth Hill had once been the most restrictive state high point. The owners had only kept open it to the public only 5-times a year on open access days. In some cases, they shot at people who tried to highpoint any other day. Brown University owned it starting in 2012 and as of October 2014, the highpoint and the access road to it is owned by the Rhode Island Department of Environmental Management’s public lands. Previously access was 8am to 6pm, but others have reported it is open all the time, and that may be the case now that it is owned by the State of Rhode Island. If anyone finds there is a restriction, let me know.
The highpoint area is attractive, as is this part of Rhode Island, with lakes and verdant trees along the road. The summit is a large rock about 200 yards from the road, (ie. less than a 5 minute walk over flat ground. You only gain about 10 feet from the trailhead.) It would be about 250 feet if you started at the bottom of "the hill" by the Alvia Chase Reservoir, still in Connecticut.
