The Galapagos has been a leading model of eco-tourism for years, but even the best-laid plans can feel stale if you're looking for a true off-the-grid adventure. A new Ecuador-based eco-outfitters, Opuntia, is starting to offer a new alternative to the islands’ classic sailing trips with well constructed tours of the Galapagos’ rugged interiors. They offer multisport adventure tours based out of boutique hotels on three different islands in the Galapagos. Think hiking active volcanoes, mountain biking coastal wetlands, kayaking with sea turtles and sharks, and snorkeling with sea lions. ROW Adventures offers land-based Galapagos itineraries, as well.
