The Best Day Hikes
Emerald Pools Trail System: If green is your color, you'll love this trail -- algae keep the three pools glowing a deep, rich, and yes, emerald green. The first part of the trail leads through a forest to the Lower Emerald Pool, with its lovely waterfall and hanging garden.
East Mesa Trail: Allow a full day for this 6-mile hike, which is an easier and shorter route to Observation Point than the Observation Point Trail. From the promontory, you'll get spectacular views down Zion Canyon, with the Great White Throne in the foreground and Red Arch Mountain beyond.
The Best Backcountry Hikes
Hiking the Narrows: This is an experience unique to Zion National Park -- a hike through a 1,000-foot-deep canyon, with water filling it from side to side in most places. Although much of Zion is dry rock, this is anything but, and it's an incredible experience for those in good shape and with strong nerves. It can be experienced in three ways -- as a short day hike, a full-day hike, or an overnight hike -- but all involve getting wet. Warning: Because the Narrows is prone to flash flooding, check weather forecasts and flash-flood potential carefully before setting out.
