Our Staff, Guides & Associates

Providing trouble-free, enjoyable adventures requires constant attention to details where it counts—at the trip location. So we carefully select some of the most important people on your trip—our overseas partners, who work exclusively for INCA travelers. Our thoughtful and caring friends in Ecuador, Perú, Galápagos, and Turkey do it all—from getting roses for your sweetheart to tracking down missing luggage to finding a doctor. They're on call, 24 hours a day, just to take care of you.

Back in the Emeryville office, we plan and organize your trips with exacting detail. We build and maintain close relationships with each vendor to ensure you get the best service through our partnerships. INCA employees regularly travel to the destinations to further their knowledge of the wildlife, guides, museums, site visits, yachts, hotel accommodations and trip content to make sure our adventures are continuing to exceed INCA standards.


The naturalist guide is the most important element in any trip, especially with a destination like the Galapagos. Were it not for the right person to reveal the hidden secrets of the landscape and animals, the Galapagos may all seem a bit boring. These talented teachers make the landscape come alive and reveal what Darwin learned from this magnificent landscape.

Patricia Stucki

Patricia Stucki

Patricia Stucki was born and raised in St. Gallen – in the eastern part of Switzerland. Her interest in Galápagos was awoken when she was a girl selling Swiss chocolates to protect this archipelago.

Working as a journalist for the Swiss news agency and newspapers as well as writing articles for magazines awoke in her a genuine fascination for travel and natural history.

Her journeys took her to Asia, Australia and Central America and finally in 1996 landing in the Galapagos where ocean and islands captured her awe. Her work as a naturalist and dive guide in the islands are coined through her passion for flora and fauna.  When she’s not on board guiding she enjoys her home, garden and a little Cocoa plantation in the highlands of Santa Cruz Island. She’s dedicated to photography on land as well as underwater and active as a conservationist. She speaks fluently Spanish, English, German and French.
