We met a couple while walking on Edisto Beach, and they mentioned a beach owned by DNR of SC, Botany Bay Plantation. This is an old plantation that was deeded to the state of SC a couple of years back. It is over 3,000 acres! It has a large protected beach north of Edisto Beach, across the sound from Seabrook Island SC.
The plantation is on a dirt road, which you turn into by the 'Edisto Tree' landmark. It's probably a mile down that dirt road.
You will have to park your car and walk about 1/2 mile to the beach, which at a slow pace for us is about 15 minutes. Once on the beach, you will notice the abundance of large seashells. You are not permitted to take any home with you, so the beach is in a natural setting as all of the beaches would have appeared prior to development.
It is stunning to see all of the shells, and so many large shells!
We walked south for about 30 minutes before turning around.
Our total time: 15 minutes walking to the beach, 30 minutes south, 30 minutes back north, 15 minutes out, for a total of 1.5 hours.
It was something to experience, and we would recommend it!
There is no charge (4/15/2011) to access any of this, at this time.
