A class 3 route up Chair Peak. This route is doable without any ropes. The route shows an optional rappel down the Beckey route (class 4).
There's one section with bad exposure where a static line (10m) may be useful to hold on to, though it's not a requirement for experienced scramblers.
A helmet is basically a requirement since there's plenty of loose rock and rocks will likely be kicked down by your scramble partners.
