The sea opens in a bright, glassy arc as the skiff slides away from Santa Cruz; salt stings the air and basalt spires appear like the bones of an ancient reef. By midmorning you’re stepping onto Bartolomé’s short lava trail and climbing roughly 400 wooden steps to a viewpoint that throws the islands wide — the pinnacled rock jutting like a marker of place and time.
