Great hiking trails and some incredible views. The trails are VERY rocky. I walked up to the south lookout then took the river of rocks trail to Golden Eagle (which is very steep) to the skyline trail. Skyline was really fun! It wasn't to strenuous but you do a bit of rock climbing if you take your time you'll have a great time. They say between 3 - 4 hrs, if you have any experience and are in reasonable shape, it shouldn't take you anymore than 3, unless you stop and take in some of the views.
I hiked the loop river of rocks (red) golden eagle (yellow) and skyline trail (blue) back to visitor center. The terrain makes this trail a bit of a challenge as you have to watch the Boulder hopping and keep and eye out for the blazes. The climb up golden eagle is pretty decent but flushed 3 doe and stopped to watch. Nice to have a justified rest. There's are a couple scrambles to consider based on comfort level with hiking.
My husband and I love coming here! Lots of signs and the land is well kept for a smooth hike but maintaining natures beauty! Lots of different look out options! Going down to the river of rocks was definitely more challenging but you're able to see great views on different trails without having to do that.
Definitely get there at sunrise for great view and pics at park entrance. Very challenging - awesome views. Would make sure you know the general terrain of each trail prior to setting out. Trails are very long with technical challenges and very few respites. Ok if you are an experienced hiker but be weary if taking along beginners - would stick to lookout for novices and plan for shorter hikes on harder trails. We did 7.9 miles (lookout-->river of rocks-->eagle-->skyline-->lookout). This was my girl friend's third hike ever (she had only started hiking a few days ago). Almost ended in a breakup, but she powered through like a champ.
