Flooding has forced the state Department of Environmental Conservation to close the entry road to the AuSable Point Campground and Day Use Area.
The popular destination is located in the Clinton County town of Peru near Lake Champlain.
DEC Regional Director Betsy Lowe says the closure ensures public safety and protects the integrity of the entry road.
"We know this is an inconvenience to anglers, birders and other recreationists, but it would be irresponsible to not close the road," she said.
"Users could get hurt, vehicles could be damaged and the road itself could be made unusable for longer period of time if the road were to remain open," Lowe added.
DEC has barricaded the road and will patrol the area to enforce the closure. It will be reopened once waters have receded.
Lake Champlain reached flood stage earlier this week, prompting the National Weather Service to issue a flood warning and advisory.
