Big Trek, Big Trouble, Big Surprise

 is the first episode of Survivor: Guatemala.

Challenges
Reward Challenge: 11-Mile Hike 

While bringing all their supplies, the tribes must race through the Guatemalan jungle to reach a Mayan pyramid. First to reach the ruin wins reward.

Reward: The winning tribe will live at the ruins and will also receive a piece of flint.

Winner: Nakúm

Immunity Challenge: Paddle Battle

Using their canoes, the tribes would paddle out to buoys in the lake to retrieve a torch hung from each buoy. Racing back to shore, four members would run to the top of the hill and begin hauling up the canoe with a rope. The remaining tribe members would rotate logs underneath the canoe, allowing it to roll up the hill, much like the technique the Maya used to move large items. Once the canoe passed a finish line, each tribe's remaining member would run to the top of the hill with the torch and light the victory cauldron. First tribe to light the cauldron wins Immunity. Additional Stipulation: If Yaxhá wins, they would get flint. Winner: Yaxhá
