Famously known as the oldest continuously operating trading post on the Navajo Nation (it's been here since 1876), Hubbell Trading Post is part historic site, part museum / gallery, and part thriving retail operation specializing in authentic Navajo rugs, jewelry and pottery. A visit to the adjacent Hubbell family home - with the impressive collection of Southwestern art and Native American arts and crafts - is highly recommended.
If you go:
Hubbell Trading Post is open from 8:00 a.m. to 5:00 p.m. daily (except Thanksgiving, Christmas & New Year's Day). Tours of the Hubbell Home are guided and cost $2.00 per person.
