Galapagos. Las Bachas (Santa Cruz).The sand at Las Bachas is made of decomposed coral, which makes it white and soft, and a favorite site for nesting sea turtles. The Sally Lightfoot crabs are abundant on the lava rocks along the water’s edge. These crabs will eat anything they can get their claws on. On this hike, we saw flamingoes, Sally Lightfoot crabs, hermit crabs, black necked stilts, and whimbrels. The sea turtles had already abandoned their nests.
