Sinks Canyon is a premier climbing destination. Within a few miles, the rock changes from sandstone to limestone, and then to granite as you get closer to The Wind River Range. There are fantastic climbs on the sandstone and granite, but the sport climbing on the Dolomite is where Sinks really shines. If you are not a sport climber, there is access to trad climbing on the granite and sandstone, as well as bouldering on all 3 rock types. The rock quality is generally excellent. You can find everything from hand swallowing pockets in the Killer cave to perfect overhanging crimps on the Addiction Wall. There is climbing for every ability here from 5.6-5.14c. While there are gems of every grade, the most classic climbs are 5.10 and up.
As far as access goes, it doesn't get much better than this. Sink's is the closest climbing area from town, it is about a 10 minute drive to the Main Wall parking lot, and about a 15 minute approach (depending on how atrophied your sport climber legs are). Make sure to bring plenty of water and extra layers, no matter what time of the year it is.
You can climb at Sinks all year, but the best temps are during the cooler months. While the rest of Wyoming is a frozen wasteland, the Main Wall is often baking in the sun. It can be 0° in town and you can be climbing in a T shirt. Believe it or not, the south facing side of Sink's Canyon is one of the best winter climbing areas in the United States.
Steve Bechtel's Lander Rock Climbs 2023 is a must have for visiting the area and will give you much better information and directions than Mountain Project.
Watch out for 1) afternoon thunderstorms rolling off the Winds 2) numerous rattlesnakes and 3) locals who have 'Killer' wired.
Crags L --> R
Sinks Canyon is basically one long cliff band (plus a few boulders on the hillside with routes). Here is the relative position of the Sinks crags:

Granite Far West
--> Squaretop Boulder (on the hillside below the Moss Cave)
--> Wave of Mutilation (on the hillside below Addiction)
--> Scud Pinnacle (on the hillside below Scud Wall)
Down Canyon Sandstone
Dog Retention Units (DRU's) can be found throughout the park. Look for the cold shuts near the nice puppy pads, especially in the Killer Cave-Scud Wall region.
