I've been wanting to do this hike for a while. This is possibly THE signature hike in Boulder. The goal is to hike all 5 peaks: Bear, South Boulder, Green, Flagstaff and Sanitas in one day. We won't necessarily rush it as it's an absolutely stunning hike .

Starting at the South Mesa Trailhead, follow trails up to South Boulder Peak (8549'): one section of trail gains 1600' in 1 mile, making it perhaps the steepest trail in Boulder. Then, proceed to Bear Peak (8461') followed by Green Mtn (8144'). As we approach Flagstaff Mtn (6898'), we'll cross the road a few times; there are many trail crossings so it will be a bit of a navigational challenge to ensure we follow the right trail. Finally, we will get to the lowest point of the trail, basically, downtown boulder before we tackle our final peak, Mt Sanitas (6791').

Stunning scenery

The "city" portion of our hike: go from Viewpoint Trail to Settler's park

The total distance is a over 16 miles and vertical gain is 5400'.

Note this is a strenuous hike due to the distance, elevation gain and sometimes challenging terrain.

I will post a more detailed route description as we get closer to the date.

Please make sure you have adequate food and water, a map/GPS, headlamp and CAMERA!

Finally, bad weather postpones!!
