Climbing and access information for this peak is on Page 251 of the book. Updated November 2018
Big Basin Peak is located at the head of Big Basin between Old Hyndman Peak and McIntyre Peak. The South Ridge is the most popular route. The three trip reports linked below cover this route in detail. It was thought that climbing the peak from any direction requires Class 3+ scrambling. However, Derek Percoski recently located a Class 2/2+ route up the peak’s South Side. Derek’s GPS track is set out below. USGS Grays Peak

Derek Percoski’s GPS track for his Class 2/2+ ascent. Derek states: “To avoid scrambling, you must zigzag your way around the shelves from 9,500 feet to 10,500 feet, but it’s equal to or easier than making your way back to Salzburg Spitzl, which is rated Class 2. I’ve attached a path of the general route I’m describing. Once you gain the ridge, that side of the summit is quite easy (see next photo).”
