Big Basin Peak appropriately sits at the head of Big Basin between Old Hyndman and McIntyre Peak. It was thought that climbing the peakfrom any direction involves Class 3+ moves. However, Derek Percoski recently located a Class 2-2+ route up the peak’s south side. Derek’s GPS track is set out below.

Derek Percoski’s GPS track for his Class 2-2+ ascent. Derek states: “To avoid scrambling you do have to zigzag your way around the shelves from 9500 to 10500, but it’s equal to or easier than making your way back to the Spitzl, which is rated class2. I’ve attached a path of the general route I’m describing. Once you gain the ridge that side of the summit is almost nothing (next photo).”
