You used to make reservations to park at Ramsey Canyon, now it's first come, first served. The lot has been expanded a bit, though, so if you arrive reasonably early, you should be able to park. You can get information about what's around at the Visitor Center and gift shop, and you can read the trogan bird alert at the foot of the trails.
First stop is the hummingbird feeder area.
I had heard that a berylline hummingbird had been seen, but I was shocked and delighted to see it myself. Fourteen species of hummer have been seen in the canyon. Conditions are better for photography at the Paton's in Patagonia , the Chuparosa in Madera Canyon, and at Beatty's in Miller Canyon . I didn't know quite what to make of all the little flags sticking out of the ground along the trail. I talked to a volunteer who explained that very tame deer were eating up everything along the canyon.
