Get up to Mt Whitney on the Southern Sierra High Route. Pretty straight forward off-trail route following a valley up to a pass, then a big scramble down and up to the Whitney Ridge and then a short scramble down to the trail that will take you to Mt Whitney. Snow will likely be present, but will not be much of an issue other than the short scramble down to the Mount Whitney Trail, which is quite steep and you must be aware of hikers passing below. Summit Whitney with a little more adventure less out-and-back. If you’re feeling adventurous, continue the Southern Sierra High Route north, descending Whitney using the mountaineers route.
