Castle Rock is the largest formation not just in Castle Rocks State Park, but in the entirety of the City of Rocks area. Although the Twin Sisters are no doubt taller, Castle Rock offers broader faces and thus the most established climbs on one feature in southern Idaho. Due to Castle's size and ease of access from the main trailhead at Castle Rocks State Park, it is also the busiest formation in the park. That being said, it draws most attention to its easier sport lines leaving several stellar cracks wide open no matter the holiday or season.

El Castleton, 5.10

The west face of Castle Rock starts with the popular arête route named Red Rib (separating the west face from the south face) and runs up into what they call Hostess Gully which is how you access the north face. Therefore, the majority of these routes receive a ton of afternoon sun and make for good cold weather climbing.  El Castleton (5.10) and Southern Rock Opera (5.11d) are two of the finer cracks in the entire City of Rocks area and Bingham gives them their due in his local guide.  Popular sport lines include Red Rib (5.10a), Between Heaven and Earth (5.9), Zinger (5.8) and Fruit Pie (5.7). The routes on the right side of the wall located on a separate buttress can all be done in one pitch but most will require doubles to rap. Many of the routes on the left face require multiple leads to the summit.

Park at the main Castle trailhead. Do not park in non-designated parking spaces, I have seen the rangers give tickets for that, rather use the overflow parking back near the ranch house if the main trailhead is full.  Hike west towards Castle Rock and circumvent it to the south via a well-established trail. The climber trails up to all the routes on Castle are well established.

Dow Leading Twinkie, 5.10c
West Face
Routes Listed Right to Left as you face the Wall
  • Red Rib- 5.10a***/I don’t agree with Bingham’s assessment of three stars for this route, but then I am not much of a sport/slab climber. The position is fun as it takes the arête that starts the west face. I actually preferred the Numbshall lead just to the left, but it is much less popular. El Castleton is by far the best of the three, all the same grade, all share the same belay spot, but have their own anchors. Dow

  • Numbshall- 5.10a**/As I said, I preferred this line over Red Rib. It does offer a gear placement or two and is a bit steeper and more varied. Dow

  • El Castleton- 5.10a***/This is the best route I have climbed on Castle Rock to date. It follows an obvious arching crack in the middle of the face to the left of Red Rib. You solo up the chimney and then I ran it out a bit up the face to access the crack. It does not see much traffic based on a bit of cleaning I did, probably just due to the fact that most folks climbing on Castle are sport climbers. The crack is a bit flared, mostly fingers at the crux. El Castleton eases off at the top, move right up big jugs to its own anchors just above Red Rib and Numbshall. Climbing this pitch is a great opportunity to warm up and scout out Southern Rock Opera which is another incredible arching crack to the left. El Castleton takes a full assortment of finger gear. Considered a bit stiff at the grade by the locals and I agree, prob more like 10b or c.  Dow

  • Fruit Pie- 5.7***/

  • Zinger- 5.8***/

  • Twinkie- 3 Pitches- 5.10c***/Fantastic 1st pitch.  The first move is bold but protected with a low bolt.  The crux is past the 2nd bolt.  A delicate sequence that you must get wired.  Almost a small dyno action.  You can protect with a micro cam between bolts 3 and 4 at the crux and then higher when it turns to good fingers you can get a bomber C4#.4 in as well.  Some fun 5.10 edging trends left and up to an anchor.  I prefer to combine the first two pitches.  From this anchor, trend back right to a bulge and up easier angled ground to a shared fixed anchor. Neither of the last two pitches offer any 5.10a climbing even though referenced as such in the guide.  The last pitch heads up an easy corner past a bolt and follow the bolt line up easy ground to a chain rap just below the summit. Dow

  • Ho-Ho- 5.10d**/

  • Piece of Cake- 5.7/

  • It Takes Two- 5.8**/

  • Between Heaven and Earth- 5.9***/A tall bolted line, 15 bolts or so. It is fun but not sustained for the grade. The small roof move off the deck might be the crux although still probably at a lessor grade. Rap with two ropes. Dow

  • Blind Pig- 5.10a*/This is a better route than Between Heaven and Earth. It offers two neat cruxes with the upper slab moves pushing the grade. Climb up just left of Between Heaven and Earth and follow the bolts (10+)  to the right of the large blank section of the wall. The route trends left. Pull the roof easily to the start of a vertical slab section with a few intricate moves to the fixed rap. Can rap with a single rope.  Dow
