Las Grietas, which means the cracks, is a deep fissure in the volcanic rock where fresh and sea water mix in a long, narrow, startlingly clear pool. Sunlight slants down between high cliffs, the water is cool and deep, and visitors swim, float and snorkel in a canyon that feels like a natural swimming hole. Getting there is half the fun. From the main pier in Puerto Ayora a small water taxi crosses the harbour for a small fare, and then a marked path of about fifteen to twenty minutes leads past salt flats and cactus, with lava lizards underfoot, to a steep wooden stair down to the pool. The last stretch has some rocks to scramble over, but the effort is small. The site is part of the national park, and on busy days the canyon fills up, so go early in the morning or late in the afternoon. It is one of the easiest and most photogenic swims on Santa Cruz, and a rewarding way to spend an afternoon that does not need a boat or a guide.
The water in the main crevice is cool and slightly brackish, with excellent visibility, and the walls rise on both sides so the pool stays mostly in shade. People enter from a platform or the stone steps and swim the length of the canyon, which is only a couple of dozen metres across but surprisingly deep. Snorkel gear is useful, since you can see small fish, though the experience is more about the setting than the wildlife. Check the rules posted at the site and follow staff instructions.
Planning
Bring swimwear, a towel, water, sun protection and closed shoes for the path, which crosses sharp lava rock. Carry a few small dollar bills for the water taxi and any site fee, and a waterproof bag for valuables. Morning visits are quietest, and the light is best when the sun is high enough to reach into the crack. On the way, the path passes the beach at Playa de los Alemanes, a good spot for a post-swim rest, and a small cafe near the start sells drinks.
Good to know
The walk includes uneven rock and a final steep stair, so it is less suitable for people with mobility limitations. The water is cold enough to make a short swim refreshing but not warm, so a rash vest helps. Treat the site gently, take rubbish with you, never use soap or lotions in the pool, and keep clear of the walls. Combine Las Grietas with Tortuga Bay on another afternoon or the Darwin Station in the morning for a pleasant day without booking a thing.

Good questions
How do I get to Las Grietas?+
Take a water taxi from the main pier in Puerto Ayora across the harbour, then follow the marked path for about fifteen to twenty minutes to the canyon.
Can you swim in Las Grietas?+
Yes, the pool is deep, clear and cool, and visitors swim and snorkel in it. Follow posted rules and staff instructions at the site.
Is it free?+
The path and pool are part of the national park, so your park entry fee, paid on arrival, applies. Carry small bills for the water taxi and any local site fee.
Is it suitable for children?+
Older children usually manage well, but the rocky path and steep final stair are tricky for small ones, and the water is deep.
When is the best time to go?+
Early morning or late afternoon, when it is quieter and cooler. Midday brings crowds and heat on the exposed walk.
