Zion National Park open year round. In the springtime, temperatures are comfortable and precipitation is light. Streams from melting winter snows plunge down many sheer sandstone walls. Grasses and wildflowers abound. Photography is especially rewarding at this time of year because the flowers are in bloom. Bicycling, hiking, horseback riding and bird-watching are all popular springtime activities at Zion. Most hiking trails are open in the spring, with the possible exception of the high country. The Pa'rus Trail, a 1.75-mile hiking and biking path by the Virgin River has wonderful views of the open canyon. 

Summer is the busiest season at Zion in terms of the number of visitors and the range of activities. Free interpretive talks, shuttle tours, audiovisual programs, guided hikes and evening programs take place daily. Enjoy wading in the Virgin River but be cautious because flash floods are dangerous and very unpredictable. For your safety, do not wade in rushing waters. 

Zion is spectacular in late autumn. Colors are at their peak and temperatures are comfortable. 

Winters are generally mild and snowfall is light. Snow may accumulate on the higher plateaus, which makes for good cross-country skiing.

Main roads through Zion and those leading into the park, except the road to Lava Point, are kept open and passable. Most higher-elevation hiking trails are closed in winter. Zion Lodge and one campground are open all year.

Walking & Hiking

A variety of trails crisscross Zion. Before starting out, consult the free Zion Map & Guide, available at entrance stations and visitor centers. The key to successful hiking is to become familiar with each trail and know your limitations and abilities.

• Before hiking in any of Zion's narrow canyons, check at the visitor center for the current weather forecast. Failing to do so can jeopardize your safety.

• Most trails in Zion have precipitous drop-offs, so stay back from edges and always watch your footing.
