Hi! I hiked the PCT last year and stayed at the Mellow Mountain Hostel for a nero! Really great atmosphere, clean accommodations, plenty of places to hang out (tech room, large communal kitchen area, patio/outdoor area), and really close to plenty of restaurants, the grocery store (Raley’s, which is I believe Vons/Safeway), and main gear shop. I felt safe and like my stuff was safe as well. Lots of fellow hikers (both PCT & TRT) and non-hikers as well. Only downside was that there is a certain time to wait until laundry opens (maybe around 4-5PM) and there’s kind of a mad dash. Really enjoyed the stop, though– happy to answer any specific questions you have. 🙂
Hope this helps.
