Avanti Destinations is giving travelers an intimate view of the rich flora, fauna and natural wonders of the Galapagos and Patagonia on its new small ship cruises for eco-adventure itineraries. The first of two vessels, the M/C Petrel, features eight luxurious cabins with private balconies and a jacuzzi for unwinding after explorations. The ship will sail the Galapagos Islands on 3- and 4-day itineraries starting at $4,095 pp dbl.

Meanwhile, the newly-built Ventus Australis will begin sailing along the Patagonian coast off Argentina and Chile in January 2018. The ship is being built to enable it to travel between the narrow fjords and channels of Patagonia, allowing passengers to get an up-close view of the massive glaciers.

In addition to small-ship cruises, Avanti offers accommodations, add-on tours and transfers in both regions, such as the new customizable, 3-, 4- or 7-night Galapagos Luxury itinerary, starting at $5,595 pp dbl, which includes accommodations at a 5-star, all-inclusive hotel on Santa Cruz Island, eco-tours, yacht exploration tours, all meals and transfers, as well as the national park fee.
