The Main Entrance on this tour is at the bottom of the map. The tour goes straight in (up), then to the right circling the first block.
The old two story buildings are now used for storage or in the case of Olsen Hall, has been converted to Rainier Mall which has a few stores for residents and non-residents alike.
Fully circling the block, will put you back at the Administration Bldg. On the left side of that building in the basement is a great old fashioned coffee shop. Friendly folks and the best shakes in town. Consider giving it a try.
