Beautiful views of boulder. Steep hike, however you can drive up most of the way on some very windy roads. Watch for bikers, there are a lot of them. Simply breathtaking!

Our first time to drive up this twisty mountain road that offers gorgeous scenery; how did we miss doing this drive for 25 years? It is beautiful! We enjoyed the views at various pull-offs, then enjoyed sunset. At the ampitheater, we watched the lights start...More

We went early in the morning so there was little traffic. We watched the sunrise from the amphitheater, hiked the easy tenderfoot trail with great views and also hiked the west ridge trail to Green Mountain summit. This trail is the easiest way to the...More

Camping isn't allowed in Boulder's Open Space and Mountain Parks area, which is the area Flagstaff is in. If you do a web search for camping near Flagstaff you can find some nearby (though not easily walkable) places.
