I've always had a dream of one day trekking the Himalayas in Nepal. Before I make that journey I want to get a taste of mountain backpacking at home in the US. Are there places I can get a comparable experience to a Himalayan trek? Things like multiple biomes in a 4-5 day span, high mountain lakes, deep valleys and such. I live in Arizona, so I am no stranger to mountains although the ones here aren't exactly what I'm looking for. Maybe in the Rockies or the Pacific northwest? What do you say /out/?
