This is the classic beauty spot of the Galapagos Islands. The view from the top of the island and the volcanic landscape is spectacular. Pinnacle Rock is the eroded remains of a tuff cone. A small submerged crater can be seen just offshore. To the east there are a series of small spatter cones. Snorkeling is excellent close to Pinnacle Rock. A trail leads across a sandy isthmus to a sand beach on the south side.
