My wife and I hit the trail just before 8:00 am on July 12, so it was hot. Trail is flat and very easy for the first 3 miles or so. If you finish the hike to Penasco Blanco, it gets steep and passes over bedrock, so be sure to watch for the cairns. The petroglyphs and pictographs are awesome. All told, it took us about 4 hrs of actual hiking, with about 1 hr of picture taking and breaks. Did I say it was hot? Bring lots of water, use sunscreen, and wear a hat.
