Battery Beach is a tiny, forest-framed cove where turquoise water meets dark volcanic rock. Sand is limited, but on quiet days it’s the place to float and let the colour do the work. Snorkelling is easy close to the rocks when the sea is flat; bring a mask and reef shoes. Access is either on foot via a steep path, which is definitely not suitable for pushchairs or those with mobility issues, or by boat dropped directly into the cove, which isn’t any better.
If the sea is choppy, the boat option is a battle. Expect spray and awkward landings, so pack valuables in a waterproof bag; careless trips have cost people (including me) power banks and cameras. There are no facilities; shade comes from palms. Battery Beach earns its place for water clarity, drama, and seclusion, not for wide sand or services. Weekdays are calmer; leave no trace but footprints, take nothing but photos and memories.
