June 26, 2010 I went to Gooding City of Rocks instead of "Little City of Rocks", it was worth it! The confusion started with the description on the IAMC website, it stated:
Gooding City of Rocks
City of Rocks is an area of unusual and highly scenic rock formations. Erosion has carved fascinating spires and hoodoos from the underlying deposits of solidified volcanic ash. Excellent hiking, sightseeing and solitude.
Location: About 15 miles north of Gooding on Highway 46, turn west at the BLM sign for City of Rocks. Follow the signs and travel about 7.5 miles on a generally well-maintained dirt road, which is suitable for passenger vehicles if conditions are dry.
