How about a Google map that shows all the significant Portland area rock climbs and bouldering spots on a single map?
Yep, we thought you might like that.
Click each label for lat long coordinates, guidebook, MountainProject link, and comments.
Pro navigation tip: Copy paste the coordinates into Google or a smart phone mapping app to get a map and driving directions to the location. (Note that driving directions can get wonky on boondock roads.) Also, the guidebooks have good written directions.
Please support your local guidebook authors, buy the book listed in the description.
