Show up by 9am or you’ll be elbowing cruise ship crowds for a photo inside the Cathedral Room. Scramble through the massive granite boulders and tide pools to reach Devil’s Bay—it’s the best spot to swim without the heavy traffic. Skip the overpriced group excursions; hire a private charter so you can actually linger when the water is calm. Bring a waterproof phone case and sturdy water shoes. Two hours here is plenty.
