Bob's info is correct.
Many of the homes along this coastal area have Association Access, or Deeded Access to private beaches.
Obviously, further research is required to confirm this. There are also a number of Township Beaches.
As an Accredited Buyers Agent, I would be happy research any properties for you.
That property is roughly 2.25 miles from the New Buffalo Public Beach, about 14 miles north to Warren Dunes State Park in Mi., about 10 miles to Indiana Dunes near Michigan City in Indiana.
Let me know if you need more info.
