Pacific Crest Trail

If you are looking for extreme hiking try the Pacific Crest Trail. According to Wikipedia the Pacific Crest Trail is attempted each year by about 300 people that attempt to hike the entire trail from end-to-end. The trip usually takes between four and six months. Around 180 complete the hike each year. Most hikers start from the Mexican border and reach the north end of the trail before the first hard snow. Picking up supplies along the way, usually packages sent to them via mail, most hikers cover about 20 miles (32 km) per day.

Here is a interesting two part video that was the winner of the California Independent Film Festival (Best Documentary) and Vancouver Mountain Film Fest (Jury Award) called "Walking the West." It is about a New Zealander and an Irishman who quit their jobs, cashed in their savings and walked 2626 miles from Mexico to Canada along the Pacific Crest Trail.
