The park is dog friendly as long as dogs are kept leashed.
Montauk County Park was created from a series of land acquisitions by Suffolk County beginning in 1971. The parks boundaries extend all the way to the north shore from Oyster Pond, around Shagwong Point to Gin Beach by the entrance to Montauk Harbor Inlet. The park includes:
- Big Reed Pond – a National Natural Landmark.
- Montaukett Village – a home and burial ground of the Montaukett tribe of Native Americans, which includes the grave of member Stephen Talkhouse
- Deep Hollow Ranch – the first and oldest cattle ranch in the United States, established in 1658
- Third House – the third residence constructed in the 18th century for cattle keepers, who brought cattle to graze in Montauk each summer. The house is open seasonally.
- Camp Wikoff – this is the area where Teddy Roosevelt and the Rough Riders came to recuperate after the battle of San Juan Hill during the Spanish–American War in 1898
- Shagwong Point is a favorite among surfcasters, who routinely patrol the shoreline between the inlet and the Point looking for Striped Bass and Bluefish. RV camping is permitted here. This is also the entrance for Outer Beach for Off Roading by permit only.
