The best time to visit Kirkham Hot Springs depends on your preferences:
Summer (June - August): This is the peak season, so you can expect more visitors and warmer temperatures. Summer offers the best opportunity for camping, hiking, and other outdoor activities in the area.
Fall (September - October): Early fall offers mild weather and fewer crowds, making it a perfect time to visit. The foliage in the surrounding mountains also adds to the beauty of the area.
Winter (November - March): The hot springs are open year-round, but winter can bring snow, which means you may need to check road conditions and be prepared for colder temperatures. Snow-capped mountains provide a stunning winter backdrop, but access can be more challenging due to icy roads.
