As well as being the starting point for Tahquitz Rock, Humber Park also hosts a few boulders that are worth getting the shoes and pads ready.
All the boulders are located within a short stroll from the parking area, and the problems are all located on excellent rock.
In general the problems are fairly moderate in their grade, but the problems are good and worth a look if in the area.
