After convenient pickup from your hotel in Iquitos, you’ll head straight for Nauta to board a boat used for the day’s cruising. To enter the jungle, you’ll navigate a massive tributary of the Amazon, the Marañon River. Gaze at the vast wilds that surround you as you near the starting point of your jungle hike. Once you arrive at one of the jungle’s best places to observe the poisonous frogs, you’ll disembark from your boat. The frogs themselves are tiny, the largest of which grow only to be 2 inches in length—but what they lack in size, they make up for with their vivid coloring and deadly poison. They cannot be found throughout the entirety of the Amazon, but strictly in certain small habitats that you’ll be visiting over the course of the day. As you walk through the jungle, your expert guide will take you to the best frog-spotting locales—but keep your eyes peeled for other species that call this vibrant ecosystem home, like anacondas, sloths, and unique insects. Along the way, you’ll have a delicious picnic lunch, and meet some of the indigenous people of the Amazon River. After a full day of exploration, you’ll head back down river, bound back for drop-off at your accommodation.
