The City of Rocks National Reserve, also known as the Silent City of Rocks, is a United States National Reserve and state park lying 2 miles (3.2 km) north of the south central Idaho border with Utah. It is widely known for its excellent rock climbing and rock formations.

The rock spires in the City of Rocks and adjacent Castle Rocks State Park are largely composed of granitic rock of the Oligocene Almo pluton and Archean Green Creek Complex.

The City of Rocks is a popular rock climbing area, with over 1,000 traditional and bolt-protected routes. In the 1980s, it was home to some of the most difficult routes in the US, mostly developed by Idaho climber Tony Yaniro. Climbers in the region refer to the area as simply 'The City'.

California Trail wagon trains of the 1840s and 1850s left the Raft River valley and traveled through the area and over Granite Pass into Nevada. Names or initials of emigrants written in axle grease are still visible on Register Rock. Ruts from wagon wheels also can be seen in some of the rocks.

  • My rating does not count towards this monument as it is a spectacular natural place that you should visit. We planned to stay 2-3 days but left after only one as the incredible number of house flies....  more »
  • It doesn't take that long to drive the gravel roads, so why not? The rock formations are amazing, the rock climbers are entertaining, and the large amount of hiking was a total surprise. And there.....  more »
  • Cheap entertainment and a good hike. You can drive through most of the area or take a hike along the geology trail. I enjoyed the hike ad it was an easier hike.  more »
  • Such an amazing experience! We did the rock climbing program and it was incredible. Our guide Ryan was super helpful, inspiring, and great. He helped us feel confident and safe. We were with him for around 3 hours and we got to try several climbs. I would really recommend coming to the city of rocks if you love rockclimbing or want to get into it, or if you just love beautiful views.
  • City of Rocks is absolutely STUNNING. This is one of my favorite places to visit. Whether you come just to walk around or to do some climbing, it's a gorgeous place. There are TONS of climbing routes here, though not quite as many if you're a beginner. The top roping is a little scarce and a little hard to find. If you can lead climb, there's plenty to do, but there are a few more routes for trad climbing than for sport. If you have beginners, it helps to lead climb something and turn it into a top rope for them. But there are also some very beginner-friendly lead climbs. You will definitely want to invest in a book and plan where you will go ahead of time so you can hit up as many climbs as possible. It's also really nice that there is a water spigot and bathrooms near Bath rock. And you can drive quite close to any rock you're interested in with a short hike to get there. You will definitely need a pretty long rope for a lot of these climbs. Definitely look into equipment required in the guidebook before coming. City of Rocks is free admittance and only about $15 per night if you get a camping spot there. Castle Rocks costs $5 for admittance. Both are worth the visit.
  • Beautiful place, but definitely full of people during this part of the season. Be prepared for very rough roads. Don't need a 4x4 for most of the park, but you'll be bouncing around a lot. Just a warning.
  • The rock formations are awesome! This is a fun place to take kids and let them climb around on some big boulders. There are plenty of places for varying levels of experienced climbers too. The campgrounds are nothing fancy - you're in the wilderness, so just be prepared. Be smart about your activities too because the nearest medical facilities are pretty far away if you get seriously injured.
  • We go every year! This is an amazing place to go with the family, but bring a guide. There are only a few suitable routes for kids!
