From trekking the Salkantay route to Machu Picchu, to snorkeling the Belize Barrier Reef, or hiking on glaciers in New Zealand, each itinerary features a schedule of more active excursions— things like hiking, snorkeling, kayaking, rafting, glacier trekking, and more — while still incorporating the natural history, cultural interaction, and educational elements our travelers know and love. These programs are perfect for anyone seeking a more hands-on way to experience a destination.
