That’s a lot of stops and stuff for 10 days, especially if you’re in Durango for a wedding. You didn’t indicate how many days that will take. But, given my knowledge of the Southwest, having lived and travelled there extensively, here are my thoughts, keeping in mind that I kept in mind the tons of photo ops.

Ditch Sedona and Telluride. They are out of your way for what I consider little payoff. Sedona is overrated and a tourist trap. I’ve only been to Telluride once very long ago and if you’re going for the scenery, that’s your call; but, Durango is in a beautiful river valley with plenty to see. So is Pagosa Springs. Were I planning this trip, it would be based on the Google map linked at the bottom of this post. Here are my very opinionated comments.

Oatman and Kingman — The former, a little less than 4 hours from Joshua Tree, is famous for its free-range donkeys and the latter, just down the road, is famous for being on Route 66, which is much celebrated.

Flagstaff — No real comment, although it’s the gateway to the Grand Canyon’s South Rim.

Winslow — Yes, everyone can “Take It Easy” downtown by “Standing on the Corner in Winslow, Arizona.” But the real gem is the La Posada, an incredibly restored Harvey House with a restaurant to die for — the Turquoise Room, named after the old Santa Fe Super Chief dining car. East of Winslow, you’ll be near the Petrified Forest to the south and the Hopi reservation Second Mesa to the north.

Gallup — You’ll find this Navajo rez border town well worth your time. Consider staying at the famous El Rancho Hotel and check with the hotel if there will be Native American dancing downtown. Mama’s Kitchen and Genaro’s Café are really good. Window Rock, a short detour from Gallup, is the capital of the Navajo Nation — and eponymous Window Rock formation. I have a soft spot for the American Indians, so I've made it my priority to spend money with them, especially on genuine crafts which individual artists sell in Gallup and in Window Rock. As you go north from Gallup through Tohatchi and Newcomb, you’re on the Navajo rez — drive carefully and watch your speed.

Farmington — This rez border has little to recommend, although I lived there for 2½ years some 22 years ago. But, you’ll be near Shiprock, also on the rez, where you can see the peak that is part of the tribe’s creation story. It’s called Tsé Bitʼaʼí, “rock with wings” or “winged rock.” If you do Shiprock, I’ve routed you up into Cortez. If you have time, and I hope you do, try to spend time at Mesa Verde National Park. It is magic. If you want to go back through Farmington, avoid Hwy 170 through La Plata and continue east to Bloomington. It’s faster and if you can spare the time, you’ll find the Aztec Ruins, another of the many Ancient Ones Puebloan culture sites. Then take US 550 up over Cedar Hill into Durango. There are some nice overlooks into the Las Animas River valley.

Durango — One of my favorite places in the world because of the Durango & Silverton Narrow Gauge Railroad. If your wedding isn’t tied to a location, I’d stay at the Strater Hotel. Otherwise, I’ll leave Durango to your hosts/friends/family.

Pagosa Springs — Yes, there are several places in town to enjoy the hot springs, but Chimney Rock is another sacred Native American Place worth looking into.

I would be remiss if I didn’t mention Canyon de Chelly (pronounced Canyon de shay) outside of Chinle, Ariz. You need a Navajo guide to into the canyon, although staying at the top is free. And while Thunderbird Lodge isn’t highly rated, it’s Native-owned; and, it’s been there a long time. I stayed there with my parents in the 1950s.

I invite OP or anyone else to (1) hit websites for these places, (2) query me; and, (3) if any Hoggers have more recent information, I’d love to know it.
