Explore Punta Vicente Roca, a marine site of impressive geological formations, by panga—your guide helps with decoding the visible clues of the islands’ fiery beginnings. Beyond the geology, spy winged residents including Blue-footed boobies and flightless cormorants. The wildly rocky coast with a partially sunken cave provides phenomenal conditions for a menagerie of fish and green sea turtles. If conditions allow, don your mask, fins, and snorkel and dive in for a close-up view! Later, stretch your legs on a guided walk experiencing one of the most pristine islands in the Galápagos, Isla Fernandina. The island’s active volcano erupted as recently as 2009. Thousands of marine iguanas reside here, and it’s also a favorite haunt of Galápagos penguins. (BLD)

Large in landmass and young at one million years old, Isla Isabela supports abundant wildlife. At Urbina Bay, a stroll among the island’s vegetation reveals large, colorful land iguanas and perhaps giant tortoises. Crossing from Urbina Bay to Tagus Cove, scan the water for whales and dolphins that frequent Bolivar Channel from one ofLa Pinta’sspacious decks. Dropping anchor at Tagus Cove—an otherworldly landscape of eroded tuff cones—there’s a chance to snorkel, kayak, or ride a panga before hiking the backside of Darwin Crater overlooking a saltwater lake and panoramic views. There’ll be excellent opportunities for viewing penguins, Galapagos hawks, cormorants, petrified rain (bits of lava that cooled quickly after contacting water), and old signatures from pirates and whalers etched into the rock, the oldest dating back to 1836.

Today, it’s all about the magnificent giant tortoise. Touring the Charles Darwin Research Station, you’ll witness the exceptional conservation program where baby tortoises, “galápaguitos,” are reared in protective captivity until they are old enough to safely repatriate back to their native areas. Embrace Galápagos conservation by learning about threats that still endanger this fragile ecosystem. Bring your passport along if you’d like a special Galápagos stamp. Time permitting, stroll through town as you please. After lunch at the Finch Bay Eco Hotel, explore the misty, forested highlands and see the lumbering tortoises in their natural habitat. (BLD)

Your adventure of a lifetime aboard La Pinta concludes back on Isla Baltra. From here, transfer to the airport for your flight to Guayaquil—where you’ll await your connecting flight home, or if you’ve opted for our Machu Picchu extension, continue on to Quito, Ecuador for your flight to Lima, Peru.
