Located in southwestern Utah, Zion National Park is an impressive nature reserve characterised by Zion Canyon’s steep red cliffs. The park’s unique geography allows for unusual plant and animal diversity including 289 species of birds, 75 species of mammals, and 32 species of reptiles. Visitors can look forward to exploring Zion Canyon Scenic Drive, which leads to forest trails along the beautiful Virgin River. This river flows to the Emerald Pools, which feature spectacular waterfalls and a lovely hanging garden. Also along the river, partly through deep chasms, runs the Zion Narrows, one of the world's best slot canyon hikes. This adventurous route involves a fair amount of wading and swimming in addition to hiking. Other popular outdoor activities on offer include kayaking, bird watching, and visiting the historic Zion National Park lodge, built in 1924.
