In the Andes we hike through cloud forest, valleys dotted with pre-Inca ruins and along the rim of a volcanic crater lake. Routes follow cobblestone paths, dirt roads and forest trails with muddy sections, roots and substantial elevation gain and loss. Hikes take place at 8,000 to 11,000 feet, which can make them feel more challenging than the mileage suggests.

In the Galápagos, walking routes are generally easygoing on beach or dirt paths with mostly flat to rolling topography. However, they do include some sections on uneven terrain with challenging footing, such as lava rock. Biking is mainly along paved roads with some bike lanes and some short stretches of dirt road. Road obstacles can include giant tortoises, especially in the highlands of Santa Cruz Island. Kid-friendly routes are shorter with minimal elevation gain. For our bike ride, some sections are downhill with traffic and occasional debris, so kids should be comfortable controlling speed, navigating hazards and riding with cars.

This trip also includes multiple boat rides, including a two- to three-hour ocean crossing between the main islands, as well as water activities such as snorkeling and kayaking in the open ocean. Many of our guests find it convenient to use sandals or water shoes for these activities as well as for wet landings (times when we go ashore without a dock). If you bring these, consider a style with toe protection so that they can double as walking shoes (as some of our hiking terrain includes sharp lava rocks and prickly underbrush). If you are prone to seasickness, consider bringing non-drowsy motion sickness medication such as Dramamine, especially in the summer months when waters can be rougher.
