While climbing either Blanca or Ellingwood Point on its own would only be a Class 2 climb, adding in the traverse between the two mountains makes it a Class 3 effort. It is also possible to traverse between Blanca and nearby Little Bear Peak, but this exposed, rocky ridgeline requires 2-5 hours of class 4 climbing and traversing (if you forgo ropes and protection). While coveted by Colorado climbers, this traverse is not mapped as a part of this adventure.

To simply summit Blanca and Ellingwood Point, hike up the Lake Como/Blanca Peak Road past Lake Como. Once you reach Blue Lakes, you get to leave the unpleasant road hiking behind. Continue on a trail to Crater Lake, pass a series of ledges, and "follow cairns and a defined trail up the steep terrain," according to 14ers.com. Once you reach the ridge, you'll eventually go both directions to tag both summits.

Traversing the ridge in both directions requires Class 3 rock scrambling with significant exposure. Some of the scrambling takes place on loose and rotten rock, so be prepared for uncertain footing, and consider bringing a helmet. The traverse does feature some small cairns and faint trails to follow, but being able to spot your own ideal route through the obstacles is still advantageous.
