5 /5 Walter Brannock: Martin County beaches are some of the best in the state . Plenty of parking also lotS of public access points for miles. Dunes and plenty of sand and if you like being alone you can often find locations where you are the only people for a half mile. Incredible. The only negative is people do fires on the beach and use pallets with nails as firewood. Leaving nails behind so watch your step.
