City of Rocks rewards a straightforward trad rack. Here's exactly what to carry for the 5.7–5.10 granite cracks that define Idaho's best beginner trad venue.
TL;DR: A beginner trad rack for City of Rocks should include a single set of cams from 0.5"–3" (Black Diamond Camalot C4 or equivalent), a full set of nuts, 6–8 alpine draws, a 60m dry-treated rope, and a helmet. The granite is forgiving — gear placements are bomber if you seat them correctly. Don't bring a double rack yet. One set and solid technique is the right starting point.
City of Rocks is one of the best beginner trad venues in the American West. The granite is coarse, the cracks are parallel-sided, and the classic routes at 5.7–5.9 take gear beautifully. Your rack matters, but so does knowing how to use it.
What Is a Trad Rack?
A trad rack is the collection of removable protection devices — cams, nuts, hexes, and slings — that a traditional (trad) climber places in the rock as they ascend, removes after the pitch, and reuses on the next route. Unlike sport climbing, which uses fixed bolts, trad climbing relies entirely on the leader's ability to find and protect natural features.
Why City of Rocks Is Ideal for Learning Trad
City of Rocks offers several advantages for new trad climbers:
- →Coarse granite: The texture grabs rubber and gives excellent nut placements
- →Parallel-sided cracks: City of Rocks splitter cracks load cams evenly — no funky flares or bottlenecks to navigate
- →Route density: Hundreds of routes in the 5.7–5.10 range mean you can practice gear placement at a comfortable grade
- →Guide services: Multiple local guides offer trad instruction at the reserve if you want supervised practice
The Core Rack: What You Actually Need
Cams (Spring-Loaded Camming Devices)
Cams are the workhorses of your trad rack. For City of Rocks, a single set from 0.5" to 3" covers the vast majority of beginner routes.
Recommended sizes:
- →0.5" (purple/blue range) — thin finger cracks
- →0.75" — finger cracks
- →1" — hand cracks
- →1.5" — hand to fist
- →2" — fist cracks
- →3" — wide hand/offwidth intro

The C4 is the standard for a reason: bomber lobes, wide placement range, and every climbing shop in the country knows how to inspect them. Don't overthink the cam brand for your first rack. Get C4s, learn to place them, build skills.
What to skip for now:
- →Sizes below 0.3" (Alien/offset cams) — you won't need them on beginner routes
- →Size 4" and above — offwidth gear for a later stage
Nuts (Wire Stoppers)
Nuts are passive protection — wedge-shaped pieces of aluminum on a wire cable that slot into constrictions in the crack. A set of 10–12 nuts covers finger-width features that cams can't protect.

Nuts are light, cheap, and teach you to read crack features. They're also the right tool for the smaller placements that cams skip over. Buy a full set — the cost of 10 nuts is less than one cam.
Nut tool: Bring one. Nuts can get stuck. A nut tool retrieves them without destroying the placement.
Slings and Quickdraws
For trad climbing, alpine draws (shoulder-length slings with two carabiners) are more versatile than sport quickdraws. The extra sling length reduces rope drag on wandering pitches.
Bring:
- →6–8 alpine draws (120cm sewn slings with two wiregate biners each)
- →2–3 shoulder slings (240cm) for threading horns and natural features
- →2 locking carabiners (for anchors)

Rope
A 60m dry-treated single rope covers every beginner route at City of Rocks. The dry treatment matters in the high desert — afternoon thunderstorms in summer can soak a rope fast, and wet ropes handle poorly through a GriGri.

Do you need a 70m rope? Not for beginner routes. Most City of Rocks single-pitch routes are 60–80ft. A 60m rope is sufficient for everything in the 5.6–5.10 range.
Helmet
Non-negotiable. City of Rocks has loose rock on the approach ledges, and other parties above you are a real hazard on busy days. Buy a helmet before you buy another cam.

That sounds steep. It is — but a trad rack bought once, maintained properly, and used regularly amortizes over years of climbing.
What NOT to Bring on Your First City of Rocks Trad Day
- →Double rack: Unnecessary for 5.7–5.10. A double rack is for sustained crack routes where you'll place the same size repeatedly — not beginner routes.
- →Hexes: Hexes have their place, but cams are more intuitive for beginners. Skip hexes until you understand cam mechanics.
- →Big bros / offwidth gear: Not relevant for beginner routes.
- →Aid climbing gear: Leave it at home.
Where to Buy — REI vs Amazon
For gear that requires fit testing (harness, shoes, helmet), visit a REI store. For standardized rack hardware (cams, nuts, slings, carabiners), Amazon prices are typically 15–25% lower than in-store.

FAQ: Trad Gear for City of Rocks
Q: What cams do you need for City of Rocks? A: A single set of Black Diamond Camalot C4s from 0.5" to 3" covers the majority of beginner and intermediate routes. Sizes 0.75"–2" get the most use. Add a 0.3" and a 4" after you've built experience on the standard sizes.
Q: Do you need a double rack at City of Rocks? A: No, not for beginner routes (5.6–5.10). A single rack is sufficient for most single-pitch routes in that range. A double rack becomes useful on sustained splitter pitches in the 5.10–5.11 range where you'll need the same size multiple times.
Q: What rope length do you need at City of Rocks? A: A 60m rope handles all single-pitch beginner routes. A 70m adds flexibility for longer routes and rappelling, but isn't required for your first season. Buy the dry treatment — afternoon thunderstorms in summer can soak an untreated rope quickly.
Q: Are nuts or cams better for City of Rocks granite? A: Both. Cams are faster to place and more versatile, but City of Rocks has excellent nut placements in its constrictions. Bring both — nuts protect features cams can't and reduce reliance on any single piece size. A full set of stoppers weighs less than one cam.
Q: Do you need a guide for trad climbing at City of Rocks? A: Not required, but strongly recommended for first-time trad leaders. The reserve is remote — 3+ miles from a road on some approaches — and a rockfall or gear failure is a serious situation. A half-day guide session builds foundational placement skills that prevent accidents.
