After the route to Ridge Lakes leaves Lassen Park Road behind, you find yourself climbing up a beautiful drainage to these secluded lakes and basin. At this perfect lunch spot, the surrounding slopes offer a variety of opportunities for practicing downhill techniques. After your repast, you can make a side trip to either of the two passes to the west and northwest. You should avoid the slopes to the south and southwest of the lakes if avalanche danger exists.
An alternative to retracing your route on the return trip is to ski a loop to the north of Ridge Lakes and beneath the steep slopes of Mt. Diller; do not attempt this route if avalanche danger exists. From the high point of this alternate route the view is great and ahead you descend the first 300 feet in an open bowl.
Although the route to Ridge Lakes is technically marked, the markers are scarce.
