In winter, this is a great trail. For one thing, the road to get to it will probably be dry (or frozen) in winter. If wet, you'd definitely need a 4-wheel drive. Plus, there's not a whole lot of shade along this trail, so it makes for a great winter hike when the air is cold.
When we arrived at the trailhead, the sign designating it as such was down, so we had to guess that we were in the right spot - but the description from Trails.com was very accurate, and as it turned out, we were at the right spot.
The trail meanders through pinon pines and scrub oak on top of the plateau, with spectacular views of Zion Canyon unfolding as you walk. There were moments when we experienced sound depravation - no wind, no insects, no planes, no cars, and no people. It was almost spiritual. Very amazing in the twenty-first century.
Upon getting to the base of the Crags, the view looking north to Zion Canyon is breathtaking. Particularly in the low winter sunlight. The colors and shadows were so vivid. The Crags themselves are fascinating and fun to explore and poke around. After years of seeing them in the distance from Zion, it was wonderful to finally see the Eagle Crags close up and look back at the majesty of Zion.
The trail itself is not particularly difficult, and it is well marked. And we didn't see another human our entire hike, which for us made this hike the best.
