Challenge: High Diving

There are 6 diving platforms in and around the city. You only need to dive off 4 of them to complete this challenge. You may have already done the first high dive from the platform where you enter Paititi from the Trial of the Eagle (shown here). If not, no worries. There are several more opportunities. The platforms are marked with red dots on the annotated level map and mentioned in the relevant sections of the walkthrough. Follow this link for a roundup with screenshots, as well as tips for executing the swan dive maneuver.

Challenge: Changing the Weather

There are 5 purple frog totems hanging around the southwest part of the city. Lara normally can't use weapons here, but you can target the rope coils holding up the totems to pull them down in order to complete this challenge. For the locations of all 5 frogs, look for the purple dots on the annotated map and check out this page with screenshots.

Challenge: Dropping Decimals

As you explore the west side of the city, keep an eye out for hanging quipus, similar to the ones you used to swing across the canyon when you first entered the Hidden City from the Trial of the Eagle area. Grapple-swing on these 3 quipus to pull them down for this challenge. To find any you missed, look for the orange dots on the map and follow these screenshots.

Challenge: Keep Calm and Carrion

As you explore the city, you'll come across a number of condor's nests. Loot 3 of them to complete this challenge. Condor nests look a lot like regular birds' nests, but they are marked with a special condor head icon. The feathers are also more rare and so more valuable. Even after completing the challenge, you can collect more feathers to sell and use for crafting. I have not included a separate page for this challenge, but several nests are noted in the list of collectibles in the lower Paititi walkthrough, and marked with blue dots on the annotated level map.

Challenge: Dunkin' Bones

This challenge involves knocking down 3 dangling skeletons in the gorge east of the city. They're marked with pink dots on the annotated level map. You'll pass all of them on the way to Unuratu's prison cell during the 'Rebellion Lives' story chapter. If you haven't completed that section yet, follow the main walkthrough. If you missed any of the skeletons and need to return later in the game, fast travel to the Temple of Kukulkan Base Camp, which appears after the Porvenir Oil Fields level. Then follow this guide for revisiting the gorge to dunk bones.

UTURUNKU, THE FERRYMAN

This crypt is on the far side of the gorge east of the city, near the prison where Unuratu is being held during the 'Rebellion Lives' chapter. If you haven't played this part of the story yet, follow the main walkthrough. To get back to this area later in the game, fast travel to the Temple of Kukulkan Base Camp, which appears once you've finished the Porvenir Oil Fields. Then follow this shortcut to the crypt.

OLLANTA, THE POTTER

This crypt is located in the jungle west of the city. It's covered in the final Paititi section of the main walkthrough, along with the Path of Battle Challenge Tomb and Hearts and Minds/Champion's Bow Side Mission. If you explored that area but missed the crypt, either enter the Path of Battle area through the tunnel in the lower city (shown in the first screenshot and marked 'Path of Battle Entrance' on the annotated map) or fast travel to the Wild Jungle Base Camp. Follow the stream south to the crypt entrance, which is at the top of the waterfall. Check the crypt walkthrough for details and additional screenshots. (Click screenshot to enlarge.)

Achievement/Trophy: Como te Llama

This is not technically a challenge but an achievement or trophy. I mention it here because the mechanics are similar to the challenges, and it's fun to do. It involves petting 5 llamas . There are at least 8 candidates for petting in lower Paititi, indicated by yellow dots on the annotated map and mentioned at various points in the main walkthrough. You'll also encounter a few later on in the Mission of San Juan level.
