Redonda Rock is a flat-topped, steep-sided islet located roughly 25 km (16 mi) northwest of the island of Isabela in Ecuador's Galápagos Islands. Redonda measures 100 m (330 ft) long and 50 m (160 ft) wide with a maximum elevation of 67 m (220 ft). Its isolation and inaccessibility coupled with its rocky cliffs riddled with crevices and crossed by ledges has made Redonda a haven for nesting seabirds.
