There are two routes, both approximately nine miles, through the Subway and both are strenuous and require route finding, water crossings, scrambling, or rappelling. NOTE: Both routes require permits and are extremely popular. The weather is also a factor on these routes as they are prone to flash floods. Visit the NPS.gov page for full details, conditions, and permit information.
