This craggy peninsula is starkly volcanic. It has been colonized by the endemic lava cactus to form one of the largest growths of its kind in the archipelago.
The largest numbers of marine iguanas on the islands bask on lava outcrops, and bright-red Sally lightfoot crabs contrast with the dark grey pahoehoe lava. Flightless cormorants and penguins frequently nest here.
There are usually plenty of sea lions around, with the youngsters playing in the tide pools. Whales and dolphins are often seen feeding on marine iguanas.
At low tide, turtles and spotted eagle rays can be seen in an inlet from the trail. There are also tidepools where you can find octopus and damselfish. However, care must be taken when walking across the beach near the National Park sign as this is a vulnerable nesting area for marine iguanas.
This is one of the best places to snorkel on the islands. There are great chances to see penguins, sea turtles, flightless cormorants and marinue iguanas feeding on algae.
Punta Espinosa is one of the most beautiful sites in the archipelago.
