Monument Valley is absolutely incredible. This is a Navajo Tribal Park, meaning it's on Navajo land, tribal land, so there is a fee to enter and explore the park that's independent of any tour fees you may have. It's $20 for 1-4 people in one car and additional people will be $5 (not 100% sure if that's per person or just anything over 4, I'm guessing it's per person though).
If you come during the day (between 8 am and 2 pm), you could drive around about 50% of the park by yourself on a self guided tour. Be careful though because the roads are all dirt roads and your car will be covered in a layer of red dust by the time you leave the park. We could easily tell just from the cars parked in the parking lot who had just come from the park and who hadn't gone yet.
For my family and I, we booked a guided tour, which I would HIGHLY recommend if you're interested in learning about the meaning behind all the mesas, buttes, and spires you'll see throughout the park and especially if you're interested in learning about Navajo history and get a small glimpse into their way of life. If you're here just for the photos of the cool rock formations though, then I'd say you probably wouldn't enjoy the tour as much and would recommend that you just get here early enough (probably 12 pm at the latest because the park closes to self guided tours by 2 pm) to drive through the park yourself.
I love learning about the meaning behind everything though, how Monument Valley even came to be, why each rock formation is named what they're named, how the Navajo people live in this area, etc., so the guided tour was very worth it to me. PLUS, on the Navajo-guided tours, they can bring you into the park after 2 pm, so you can do sunset tours with them and ALSO have full access to the park, which is 50% more than what is accessible on a self-guided tour. Part of the reason is because a lot of these roads go through land upon which Navajo currently reside, so they only want guided tours have access to these roads and the other reason is because a lot of these pathways are much more difficult to drive through and require the skills of those who are used to driving them day in and day out.
All in all, Monument Valley is 100% worth a visit. We were coming from Page, and it is really close by from there and was definitely worth the 2 hour drive over. Monument Valley is located right on the border between Arizona and Utah, so if you're anywhere within that vicinity, stop by and check it out! You will not be disappointed! :) read more
