I don't know of any reliable method other than spending a few days at elevation. Since I've never had a problem with elevation, I usually just drive to the trailhead. Good thing - I can't take Diamox. I'm allergic to sulfa.

Spending a day, ascending 1-2000 feet, spending another day sounds like the most often mentioned method.
