"Should we just end and say 'Jurassic World in cinemas Friday' and get an Uber and head back?" the late night host said after he was exhausted from traveling only 60 feet.
On the hike, the pair discussed what they would do if they were forced to survive out in the wilderness.

The hike ended with Pratt and Corden taking a number of comedic selfies together on top of a hill that overlooks Los Angeles.
Pratt was recently honored with the Generation Award at the 2018 MTV Movie & TV Awards.
