Upon arrival at Baltra Airport, meet your guide and transfer via a short bus ride to the port of Seymour. Please note: A park entrance fee of $100 is charged at the airport inspection point.

Embark the Darwin Yacht and meet the Captain and crew. In the afternoon, visit the high part of Santa Cruz Island, “Los Gemelos” or “The Twin Pit Craters”. They are, geologically speaking, seen as craters but their formation is not directly due to volcanic action. Rather they were created as a result of the collapse or sinking of surface materials into cracks or manholes. In 1989 a circular path around the largest crater was opened, which passes through the interior of the Scalesia forest, an excellent place to observe land birds, especially the woodpecker finch and the vermillion flycatcher. Another plant that draws attention is the Galapagos guava or guayabillo tree, Psidium galapageium, which has a clean and smooth bark and branches covered with epiphytes and brown liverworts.

Spend the day exploring Santiago Island. Port Egas is a black sand beach located on the west side of James Bay and northwest of Santiago Island. South of the beach is Sugarloaf Volcano, which has deposits of volcanic tuff, the same that has formed the black sand beach. The Crater is just north of this site. It has a saltwater lagoon, which during the summer dry season becomes a salt mine.

Next head to Espumilla Beach on the northern coast of Santiago Island in James Bay. The main attractions here are a palo santo forest, beach, and the landscape. The beach is an important site for nesting marine turtles (Chelonia midas agassizi).

In the morning go to Bartolome Beach, a flagship site in the Galapagos Islands due to its beauty. Possessing masterful landscapes, its main attractions are the beaches, the dunes, and Pinnacle Rock (a tuff cone or volcanic ash sediment). Among the species present are the sea turtles (Chelonia mydas), which choose this place as a nesting site, and the Galapagos penguins. This site has two beaches: North Beach and South Beach. At North Beach you can practice swimming and snorkeling; South Beach is accessed by a small path along the mangroves and over the great sand dune.

In the afternoon go to Sullivan Bay, located southeast of Santiago Island. This site is of great geological interest. The landing can be performed either on the rocky shore (dry landing) or the white sand beach (wet landing). The length of the trail is approximately 1.5 km; travel time is one hour and a half. The area is covered by Pahoehoe lava flows (solidified lava in corrugated or accordion form). It was very active in the last 25 years of the nineteenth century - the Sullivan lava formed in 1897 and is geologically very young. The magma formed is flat, but the movement of underground lava, the rapid cooling and other eruptions led to the break in many places.

Visit North Seymour (located north of Baltra), where you can walk along a 2 mile trail. This site, in addition to South Plaza and North Plaza, Baltra, northeastern Santa Cruz, Santa Fe and part of Española, was formed by uprisings of underwater volcanic lavas. They were part of a volcanic lava table deposited in sheet form along cracks located on the ocean floor. The uprisings occurred sporadically and lasted more than a million years to reach current levels. The largest nesting colony of great frigatebirds in the Galapagos is found here, at its westernmost range. The common frigatebird is also present.

Las Bachas is the next destination, located in the northern part of Santa Cruz Island. It consists of two beaches that have a combined length of about 1 km long. The predominant vegetation is of the coastal zone. This site represents one of the main nesting sites of sea turtles (Chelonia mydas) on Isla Santa Cruz. It is a good place to see flamingos, as well as migratory and aquatic birds.

Begin the day at Punta Pitt, located at the east end of San Cristóbal Island. The trail includes an olivine beach of approximately 90 meters and a trail that ascends to the top of a volcanic tuff hill passing through several natural viewpoints. The trip is 1,400 meters long with an estimated time of two hours.

Punta Pitt is composed of volcanic tuff substrate. High winds present there have led to natural erosion. This is the only site in the Galapagos Islands where you can watch the three species of boobies and two species of frigates nesting in the same area, as there is enough food so there is no competition between them. The blue footed boobies nest in the interior (rare in the cliffs), red-footed boobies nest on bushes, and masked boobies nest in the cliffs. Another added attraction is the presence of sea lions.

This afternoon explore Cerro Brujo, located on the north coast of San Cristóbal Island. The trail at this visitor's site can be done in about three hours, including the panga ride. Its main attraction is the powder-like sandy beach, other than multiple species of flora and fauna. It is an eroding tuff cone that at several locations is composed of lava type a – a. It is formed by low-viscosity lava that contains little gas, breaks while it solidifies, and is pushed by lava continuing to flow from behind. Cerro Brujo offers an excellent landscape, where you can see Kicker Rock (geologic formation), the southern part of Upper San Cristobal, and the coast adjacent to Cerro Brujo.

Leon Dormido, also known as Kicker Rock, is a rocky formation or cone eroded volcanic toba of about 114 meters in height. It is a refuge for many sea birds, such as blue-footed boobies, as well as for sea lions. The waters around the rock are home to numerous species of fish, sea turtles, stingrays, and hammerhead sharks.

Next head to Isla Lobos, about an hour by boat from Port Baquerizo Moreno. The length of the trail is 850 meters and the estimated travel time is one hour. There is a small population of blue-footed boobies and common frigate birds nesting on this site. You can observe the two species of sea lions present in the archipelago. During the tour you go through a dry vegetation zone, substrate of volcanic rocks, and a sandy area. On the panga tour brown pelicans and several species of shorebirds can be observed. While snorkeling, it’s common to see juvenile sea lions, manta rays, and sea turtles.

On Santa Cruz Island, your tour starts at the Galapagos NP information booth and continues to the Van Straelen Interpretation Center. Proceed to the breeding center and from there begin an elevated circular path made of wood, where you can see tortoises of Española Island, ending in the tortoise exhibit corral. Tortoises of this corral are accustomed to humans; it is an excellent spot for visitors to be photographed with them. The path continues to the CDRS facilities and then to the town of Puerto Ayora.

Set off to El Chato (Tortoise Reserve) in the afternoon. Follow the trail starting in Santa Rosa, which is surrounded by tall grass and borders the boundaries of some farms. Depending on the season, it can contain mud and slippery rocks. At 1 km there is a pool of water that is filled with tortoises during the rainy season. The road to the reserve is one of the best places to observe land birds. Tree and ground finches, vermilion flycatchers, and cattle egrets inhabit the area and sometimes Galapagos rails have been seen.

Disembark the ship on Baltra for your flight back to the mainland.
