I spent a couple months working at Bandelier National Monument and loved it. Largest range in elevation of any national park: from the Rio Grande up to the caldera of the extinct volcano. Elk, golden trout and pika up high (not sure how much of the high country is open to hiking these days). Nothing compares to hearing the thunder booming down the canyons. Of course it is not the same doing the typical rushed tourist visit to see the park headquarters and museum. Los Alamos is next door...interesting history, lots of mysterious labs to drive past and the highest concentration of nerds in the country. ....Whenever anyone is going through Albuquerque I recommend the Atomic Museum....great display about everything "nuclear" - historical and current weapons.
