National Geographic Signature with G Adventures, a collection of small-group tours, has added 17 new trips for 2027.
The additions come after G Adventures reported increased demand for tours that deliver special access and expert insights. The collection is G Adventures' highest-end product.
The new itineraries bring the collection to 67 trips across 48 destinations. G Adventures introduced the luxury product a year ago.
Each itinerary includes a "signature moment," which G Adventures describes as "once-in-a-lifetime experiences," such as exploring the Norwegian Fjord Centre alongside a curator or cooking with a renowned chef in Morocco.
The new itineraries include Kenya, New Zealand, Rwanda, Sri Lanka and Iceland.
The Kenya itinerary features an eight-day trip through Samburu and the Masai Mara, featuring game drives, a visit to a community-owned African elephant sanctuary and studying the night sky with naturalists.
The 13-day New Zealand trip includes exploring the Waitomo Glowworm Cave with an ecologist, cruising through the Milford Sound and visiting eco-sanctuary Zealandia for a private dinner before a guided wildlife trek. Guests will also search for rare Hector's dolphins on a private Akaroa cruise.
