The easiest but priciest way to get to Little Switzerland, is to book a flight from Talkeetna. From Talkeetna they'll fly you up and land on the Pika Glacier. Sheldon Air Service is great at flying people out to Little Switzerland.
The cheaper and longer option is to drive out past Petersville, to Sunset and hike up along the Kahiltna Glacier, then make at turn east up the Pika Glacier.
Little Switzerland is a little secret for some sweet granite climbing in the Alaska Range. It's an area of granite walls and spires. The nice thing about it is that it has a longer climbing season than climbs off the Kahiltna and Ruth.
