Kicker Rock is the vertical remnant of a former tuff cone less than 5 kilometers to the west of San Cristobal. Both its Spanish name “Leon Dormido” (Sleeping Lion) and English name Kicker Rock imply that it is one rock only -when in fact it is a larger one 300 meters long by 100 meters wide with a maximum height of approximately 150 meters and next to it an obelisk-like rock separated by a narrow channel some 20 meters deep. When approaching Kicker Rock, Blue-footed Boobies, Nazca Boobies and frigatebirds can be observed in the air, while sea lions can be seen along the shore. Snorkelers and divers have reported manta rays, hammerhead sharks and turtles. The Spanish name implies that the geological formation seen from the south resembles a sleeping lion. An interesting explanation for the English name suggests that James Colnett in 1794 likened it to famous landmarks in Portsmouth.
