"A natural lava rock ridge protects this crescent beach, meaning its gentle lagoon makes for safe, easy swimming and snorkeling with kids. (Plus, its glimmering red-and-gold sand is too pretty to miss.) Located close to Hawaii’s last remaining traditional salt-gathering ponds (hence the name), it’s known to be a preferred hangout for Monk Seals, as well as local families. That said, in order to protect the fragile natural environment, the namesake salt ponds are off-limits to the public."
