Get ready for a true Amazonian adventure at Lago Sandoval, a stunning oxbow lake tucked away in the heart of the rainforest. Your journey begins with a peaceful boat ride down the Madre de Dios River, followed by a roughly 3-kilometer (about 1.8-mile) walk through the jungle, where you might spot monkeys and colorful birds before you even reach the water. Once there, you'll glide across the serene lake in a canoe, keeping an eye out for the resident family of giant river otters, black caimans sunning on the banks, and a breathtaking variety of birdlife.
