The Pacific Crest Trail is a 2,663 mile hiking trail.
It runs from Mexico to Canada and leads through California, Oregon, and Washington.
It passes through 25 national forests.
And 7 national parks.
Watch as Mac from the Halfway Anywhere travel blog rips through the trail in just three minutes.
So the trip took him five months but thanks to filming just one second a day, we get to experience it all in around three minutes!
