Elephant Beach is further north from Radhanagar and is popular with Indian tourists. The shoreline here was largely swept away by the 2004 tsunami and the beach is a fraction of what it used to be; however, the coral here is probably the best on the island, making this an excellent spot for snorkeling.
It's reachable on foot from Beach #7 or by fishing boat from the east side of the island; many resorts arrange snorkeling and diving trips here. A path to the beach starts from the road to Radhanagar — look for a dip in the road on a curve where there will usually be a few motorbikes parked. Several paths head off from this point, ask around for the correct one. If you choose to trek alone through the forest then stick to broad path since there are forks along the way. The walk is about 30 minutes at an easy pace with dry weather.
