I spent the day Sunday wandering around the plaza of Santa Fe. I love the architecture and the jewelry and art shops. I loved the St. Francis Cathedral Basilica and San Miguel church, the oldest church continually in use in the US are open and free to enter. The Loretto Chapel isn’t. It’s been bought by a businessman who charges three dollars a head to go into the small chapel. The claim to fame is an unsupported spiral staircase, which is cool, but since it takes about 5 – 10 minutes to see the chapel, I’d say it’s something of a tourist trap.
One tip: You don’t have to feed the meters on Sunday. So find a metered parking space. No reason to pay for parking.
Warning: it gets very hot and the sun is intense. Cover up; use sunscreen.
