- Dec 4, 2013View Source+1 re considering/checking into flights into Mammoth. This was the cheapest for me the last couple of years coming from Texas. ( Los Angeles connection). YARTS bus to Yos Valley from Mammoth.
Mammoth is awesome for tons of marvelous hike options of any length for pre or post hikes if acclimating, schedule buffering, or finish a JMT hike early.
