Can you get there by public transportation? Coming from pike street market. Thx!

With about .5 - 1 mile of walking, yes. Both bus and lightrail will get you close.

Yes, light rail to rainier beach station, transfer to 106.

Sure. Looks like you can take the 101 OR the 554 OR the link light TO the 106. Of course using Google maps to find the best route from wherever you are sure does make it easier :D Best of luck!
