"Known for being among the country's least-visited parks, this remote area typically avoids the large summer crowds seen elsewhere, offering a quieter wilderness experience. Because of staffing and access challenges, visitors should prepare to be self-reliant, check for up-to-date service and access information, and pack necessary food, water, and navigation gear." - Stephanie Vermillion Stephanie Vermillion Stephanie Vermillion is a travel journalist and photographer covering culture and adventure for Travel + Leisure Outside, and more.
