Mt Whitney Zone Forums General Discussion JMT Long-term parking: Yosemite or Portal?

I do not know the details (easily Googled, start at https://www.estransit.com), but I crossed paths with a JMT hiker last month who parked at Mammoth Lakes and took Eastern Sierra Transit down to Lone Pine, and then hitched up to the portal. He was planning to then just use YARTS to get back to Mammoth.

I hope this helps. Good luck and have a great time!
