At the most remote jungle lodge in South America, travelers can play macaw researcher for a day (and, really, would you want to play a macaw researcher for much longer?) by scaling 115-foot trees with rope, harness, and jumar. Scientists at the Tambopata Research Center perform this canopy climb daily to check the artificial nests of breeding macaws—and now able-bodied adventurers can join in on the bird's nest fest, too. You can take it easy and enjoy the eye-level view of the surrounding primary rainforest, or hustle and try to beat the guide’s record—a mere 4 minutes and 20 seconds. ($75 as an add-on activity, included in six-day adventure packages from $1,226 with Rainforest Expeditions)
