This guide to Gimnyeong Beach opens with a puzzle: the shelf underfoot is solidified black lava, yet the sand piled on top of it is strikingly white. It works through what centuries of tides deposited over that dark rock to explain the color, and why patches of stone still break through the pale sand in places. You'll also hear why surfers and swimmers rate this water among the clearest on the island.
