Panorama of Lyskamm (4527m), Castor (4223m), Pollux (4092m) and Breithorn (4164m)

Lyskamm and Breithorn both have a long summit ridge, with several subsidiary summits. Squeezed in between the two broad ones are the twins, Castor and Pollux. I'd like to do the full traverse of Lyskamm or Breithorn someday. Or even better, traverse all four of them - but that would take three long days. 2 July 2013.
