Tips for Visitors
Summer is the best time to visit for warm weather and ideal swimming conditions. Bring sturdy water shoes, especially if you plan to hike or explore rocky shores. Since fees can vary and signage may be limited, check local park resources ahead. Respect the uncrowded spots by packing out all trash—this keeps Thousand Springs inviting year after year.
