The Ucayali River is usually considered part of the Amazon because we include the longest tributary in the overall length. We did a skiff exploration up Belluda Caño, a little offshoot of the Ucayali. We observed squirrel monkeys, brown capuchin monkeys, three-toed sloths, a southern tamandua anteater, and many birds. One skiff even spotted a monk saki monkey. In the middle of the afternoon, we enjoyed an Amazonian fruit tasting from naturalist Jorge.

Later in the afternoon, we explored the El Dorado River by skiff and came across a village where local children found a porcupine in the river. We stayed out until well after dark to look for black and spectacled caimans.
