More ways to explore the area's outdoor wonders
You step onto the catamaran before dawn, salt on the air and the island silhouettes low on the horizon. The boat slices through glass-blue water; the sea seems to test you, daring you to jump in. By mid-morning the Similan granite outcrops appear—smooth, sculpted boulders rising from clear shallows—and the first masks slip on.
