Best time to go
Winter weekends can fill the trailhead parking area, and ice can linger after snow. Summer brings either strong heat and sun or monsoon rain and lightning, so check conditions before setting out. Bring a flashlight or headlamp for a late-day visit; the footing is uneven. If you want a longer hike, continue on the 3.3-mile Echo Canyon Loop; otherwise turn back from the Grottoes. The scenic drive beyond the Visitor Center prohibits trailers and vehicles over 24 feet.
