Once you've gotten lucky enough to find a parking spot at Pima Canyon and taken the asphalt road to the end, this trail sends you soaring without delay. Let the multitudes take their strollers and leashed dogs along the dirt road that leads to the start of National Trail — we prefer to get our legs and heart moving right away, and Marcos de Niza Trail is the one to do it. From the main parking area, walk to the south end to start the trail, and wind around the hill on a single-track path. If you haven't seen the inscription scratched into a rock along the trail, now's a good time to check it out. It's set behind iron bars. Don't be fooled, though — it's a forgery from the 1920s, and was not etched in the 1500s by the famous friar, as it claims. Continue up the hill — that's the main idea for a while, and you gain the ridge proper. From here, the trail is a glorious, slow roller-coaster on the ridge for a mile or so. Be prepared to go up if you're going down, and vice-versa. Finally, the trail lets you down entirely (not psychologically) and joins up with other trails. Turn around here, or keep going and make a day of it. And we don't mean to nag, but take lots of water.
