In 1998 we walked from Mexico to Canada along a route called the Pacific Crest Trail. Its 2,600 miles long approx and follows the high ground in California, Oregon and Washington states of the US. We ended up walking 600miles north from Mexico to the foot of the highest mountain range, the Sierra Nevada. Deep snow levels convinced us it would be better to continue the trail from Canda south and that is what we did. 2000miles southwards from the Canadian border at Manning Park through Washington, Oregon and Northern California back to Walker Pass in October See also our blog
