Firth, Idaho isn't a name that shows up on most climbing radar, which is exactly why the 37 routes catalogued here tend to stay uncrowded. The local crag scene centers on a handful of distinct areas — Crank Cave, RPM Wall, and The Playground among them — each with its own character and enough variety to keep climbers coming back across multiple visits. The route names alone give you a sense of the vibe: you'll find sport climbs like Bombs Away, Sweating Bullets, and Angel of Death sharing wall space with more technical lines like Lateralis and Bride of Crankenstein. Toprope Route signals that at least part of the area is friendly to those still building lead confidence, while routes like Yo Mama and Tequila Sunrise suggest the locals don't take themselves too seriously. With 37 active listings spread across multiple named walls and cave features, there's a workable spread of difficulty here. The climbing is close enough to the Snake River Plain that temperatures can swing hard between morning and afternoon, so timing your sessions matters. If you're driving out from Idaho Falls or Pocatello, this is a realistic half-day or full-day objective without needing to overnight.
The main named areas in the Firth scope include Crank Cave, RPM Wall, and The Playground. Crank Cave, as the name suggests, appears to be a cave or overhang feature, which can make it a useful option when other walls are wet or in direct sun.
The 37 routes here cover a range of difficulty. The presence of Toprope Route indicates beginner-friendly options exist, while names like Lateralis, Bride of Crankenstein, and Angel of Death suggest harder sport climbing is also on offer. If you're newer to leading outdoors, starting at The Playground or scoping out the toprope options first is a reasonable approach.

Firth sits on the Snake River Plain, where summers get hot and winters bring snow and freezing temps. Spring and fall are generally the most comfortable seasons for climbing here. Summer sessions are best started early in the morning before midday heat sets in, and a cave feature like Crank Cave may stay climbable longer into warm days due to shade.
A standard sport climbing rack with a set of quickdraws should cover most routes. If you plan to set up topropes, bring extra slings and locking carabiners for anchor building. Given the cave terrain at Crank Cave, a headlamp is worth tossing in your pack even for a daytime visit.
Access details for Firth's crags aren't formally documented in the listings here, so it's worth checking with a local climbing shop in Idaho Falls or consulting the Mountain Project community before your first visit. Respecting any posted signage and parking only in designated areas will help keep access open for everyone.
