1 Best Sight in The Galápagos Islands, Ecuador

The road to Santa Rosa, 13 km (8 miles) beyond Bellavista, is lined with giant elephant grass, avocado and papaya trees, and boughs of yellow trumpet vines, all of which are in marked contrast to the dry, cactus-spotted lowlands. About 2 km (1 mile) beyond Santa Rosa, look for a pair of giant sinkholes called Los Gemelos (the Twins), one on either side of the road.
