Hi in September we are travelling to San Francisco. As part of this journey I will be doing a retreat for 4 days in Mt Shasta so we thought we could take our time (say a week) to go by train on the most scenic route to Mt Shasta. Any ideas what might be the easiest way to do this. We can hire a car closer to Shasta if we need to. I am told the Coastal Starlight Amtrak train is wonderful but now sure where to stop and what is worth seeing on the way and how we may get from the coast to Shasta. I appreciate any help with this.
