Other mistake: In the motel room after the lead character's one night stay, she is seen repacking her hiking and camping equipment which is splayed across two single made-up beds, one of which should have been slept in. (00:05:00)
Visible crew/equipment: In the close-up of the horses' eyeball, the cameraman and his camera are visible along with possibly Reese Witherspoon to his left. (01:00:35)
Continuity mistake: When Cheryl emerges from the store and begins talking to the club representative distributing flyers, the lemonade she is holding has the cap off in one shot, then on in the next. It switches hands and then disappears entirely. The flyer she holds also switches hands.
Factual error: In the close-up shots as she reaches her destination at the end of the trek you can see streaked highlights in her hair right back to the roots. If she had been trekking for three months they would have grown out quite a long way, given the lack of regular salons in the wilderness.
Factual error: At the start of the hike on the PCT she spends 10 days or so crossing the desert wearing only a tee shirt and shorts. At the end of 10 days she has no tan and there are no tan lines. Also, it appears she has no tan after walking for 80 days.
Factual error: After hiking a thousand miles, she still has incredibly clean boot laces.
Continuity mistake: In the first stage of her walk she can't heat water because she has a red gas canister, and the instructions she reads say she needs a white canister. She then buys a white canister at the next store, happy she can then heat her food. But then she is seen cooking with the red canister, which supposedly doesn't work.
Continuity mistake: In the scene when she crosses the road in Washington or Oregon, her hair is pulled back behind her ears before she enters the road, loose and hanging in the middle of the road, and pulled back again on the other side.
Continuity mistake: About where she's heading 5 miles, in one shot Cheryl's (Reese Witherspoon) watch and bracelet are on her left wrist and in one shot they are both on her right wrist. Then throughout the rest of the film, Cheryl's watch and bracelet are on her left.
Factual error: They claim she only took 92 days to hike the entire PCT trail... which would require hiking around 28 miles a day with no zero days. They show her spending the first month hiking around 10 miles a day... so this is doesn't make sense. They show the wrong trail head location for the PCT. They don't film on the true Northbound trail head location (The border would be in view). They claim Kennedy meadows is only 100 miles in... It's 700 miles in. She camps and sleeps about 5-7 miles in the first hiking day on a lovely clear patch of ground. In reality she would have to set up on a narrow path (right on the trail) uphill, as there would be no place to set up at that little of a distance on the real trail.
Suggested correction: She never claimed to want to hike the entire trail, only 1000 miles of it. She started in the Mohave desert; Kennedy Meadows South is at mile 702.2, meaning she may have started at around mile 600. Bridge of the Gods at the Oregon/Washington border (where she stopped) is at mile 2147. If she started at 600, then she actually hiked for 1,547 miles. The numbers *are* weird, but not nearly as weird as this "error" claims.
