Cornwall Beach lies just south of Doctor's Cave on the Hip Strip — a smaller, less crowded white-sand cove with the same clear water and the same modest entrance fee. The beach has a bar, loungers, and a watersports concession offering snorkelling, kayaks, and short reef snorkel trips. The reef offshore is shallow and accessible; you do not need to swim far to see fish.
For travellers who find Doctor's Cave too busy, Cornwall is the obvious alternative. Sunset here is the moment to be at the bar.
