Take the South Boulder Creek Trail from the parking lot for 1.2mi, until you arrive in a meadow.
Take the right option (a large switchback) back into the trees, traversing the slope.
Cross a bridge at the top of this slope and trend left.
The Arapaho Lakes Trail veers off once you reach another meadow and are able to see the east shoulder of Beacon Pk.
The trail goes all the way to the Rollins Pass road, where the Forest Lakes zone is.
