Access Issue: BLM Managed Lands at Castle Rocks PERMANENTLY CLOSED TO CLIMBING!! Castle Rocks State Park lands are OPEN TO CLIMBING
The BLM has amended the Cassia Resource Management Plan (RMP) to permanently close the 400 acres of land it manages in the Castle Rocks Interagency Recreation Area to staging, traditional rock climbing, sport climbing and bouldering, as well as overnight camping and development of new trails.
The adjacent Castle Rocks State Park and the National Forest Service land to the north remains OPEN TO CLIMBING, as does the nearby City of Rocks National Reserve.
Arrest and/or hefty fines are likely if caught rock climbing with ropes and gear in the BLM land.
Please respect this closure to ensure access to the open climbing at Castle Rocks is not threatened.
The "Final Supplementary Rules for the Castle Rocks Land Use Plan Amendment Area, Idaho" is located in the Federal Registry. This document gives the details on the closure but doesn't provide a map. You can check it out here: federalregister.gov/documen…
The Duke Complex is several towers just northwest of True Grit Tower (South Hills area of Castle Rocks). Routes on most side and several degrees of difficulty.
Best to park in the Upper Trail Head parking by Castle Rock - head west through Tiny Town to the next trail junction. Head north on an old road looking for signs to True Grit and The Duke Complex. Fifteen to twenty minutes - a great secluded spot with sun/shade options.
