I grew up on pajarito and it is where I learned how to ski and snowboard. After teaching my self to snowboard on the steep bumpy terrain I applied to be a snowboard instructor in Taos ski valley (a resort that is world renown for it's ski and board school). In other words learn on paja and dominate the rest of the mountains. I have also been to many resorts and ski areas in new Mexico and Colorado. And I will say I always end up coming back to paja. The terrain difficulty is second only to taos ( including Colorado mountains) and if you learn to snowboard hear you can enjoy your self on any mountain. Be ready for a challenging step and exciting experience.
Remember that pajarito IS NOT a resort. They do have a restaurant, but no alcohol sales except during events and no lodging on the mountain. Los Alamos is only 5 miles away however, And while you're there check out the WWII museum where the atomic bombs are on display. ( Los Alamos is where the atomic bombs were made)
