Sanur
Ride in Balinese outriggers - Go for a ride in Balinese outriggers (jukung) from the beach at Sanur. You'll get a wonderful panorama of the coast of Bali.
Fly kites on the beach - My boys were killing time on the boardwalk in Sanur when they saw the most wonderful kite in the shape a sailing ship. It took awhile to track down the kite vendor, but they returned with a kite, their faces shining with triumphant grins. These kites also fly well back home and "they don't take a lot of wind to stay up." July and August in Bali are especially good for kite flying
Look for chocolate chip starfish - At low tide, the beach is a wonderful place to wade in the warm water. (Wear water shoes or sandals.) You'll find starfish that look like they have big chocolate chips on their back, but don't try to eat them.
