From the Mosquito Flat trailhead, follow the Little Lakes Valley Trail to just past Chickenfoot Lake. Leave the trail here and angle toward the North Ridge.
Once having gained the toe of the North Ridge, continue to the top. To make the climb more fun/challenging, stay on the ridge proper all the way to the summit. If it becomes too difficult, exit to the south onto the lower-angled face, and continue upward.
For this climb, you will need nothing more than a casual level of fitness and a comfortable pair of shoes.
