I found this, hope it helps..............
LIGHTHOUSE BEACH. The southernmost tip of the island has what many consider to be the nicest beach on Eleuthera, but it's a little hard to get to. Unless you're blessed with a high-clearance car with great tires, or 4-wheel drive vehicle and lots of patience, I would suggest you look for other beaches. If you have a bit of adventure in you, however, a journey to Eleuthera Point - or
Lighthouse Beach - will reward you handsomely. This beach is the meeting point of the Atlantic and Caribbean and has some strong undercurrents, however, so be careful.
TO FIND IT, go straight when you see the road split at the Bannerman Town sign for a little over 2 miles. You will pass by a large lagoon on your left and many gullies and washed out areas of the road. Before you get to the beach, you will see the lighthouse on the hill in the distance and
Lighthouse Bay to the right, a nice beach itself. When you come to the sand dune area by the bay, you need to make a decision about crossing the dunes in your car. My suggestion is to park the car or jeep and take the short walk over the dunes. It's not far and will save you lots of headaches later if, in fact, your car gets stuck.
THE LIGHTHOUSE is one of the interesting features of this beach. Overlooking both the Lighthouse Bay and Beach, it is a weather-worn artifact. . . a survivor of many hurricanes, the most recent ones being Andrew and Floyd in the 1990's, and a downsized
Hurricane Frances and erratic
Jeanne. To get there, just follow the beach to the southern tip until you see a place to climb the rocks. You can go inside and climb to the lookout, but be careful! There are no safety ropes or warning signs. The floors appeared to be solid enough when we were there, however.
