Fodor's Expert Review Grotto Trail
This flat trail takes you from Zion Lodge, about 3 miles north of Canyon Junction, to the Grotto picnic area, traveling for the most part along the park road. Allow 20 minutes or less for the walk along the ½-mile trail. If you are up for a longer hike and have two or three hours, connect with the Kayenta Trail after you cross the footbridge, and head for the Emerald Pools. You will begin gaining elevation, and it's a steady, steep climb to the pools, which you will begin to see after about 1 mile. Easy.
