San Antonio Creek
About
From the volcanic meadows of Valles Caldera National Preserve, San Antonio Creek winds 20 miles through Sandoval County at an average 45 CFS. The upper section meanders through caldera grasslands as a Class I meadow stream, while below the preserve boundary it cuts into forested canyon before joining the Jemez River. Optimal flows run 30–200 CFS, though without a USGS gauge paddlers must rely on visual assessment. Valles Caldera Outfitters provides access coordination within the preserve boundaries. The creek maintains Class I character throughout its length, making it accessible water for those seeking a quieter alternative to the area's more technical runs.
River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
