The Trans-Siberian is one of my dreams, though in the current political climate it’s probably best to put it on hold. Truth is, I love all trains, local and long distance. If I had one to recommend, I would suggest grabbing the Amtrak that runs up the coast from San Diego or Los Angeles and take it all the way to Seattle.
There is something about the relaxing pace of train travel, the uninterrupted enjoyment of the passing landscape, the ability to roam around the massive moving structure and the chance meetings with complete strangers that is ultimately captivating, the epitome of slow travel.
If you haven’t the time, the money or are still leery of trains, start by moving up and down the SoCal coast on the Coaster where the stops are frequent and the scenery mesmerizing, or taking the MetroLink commuter from the Inland Empire to the beach. Surprisingly, after years of using Los Angeles as an example of how to build a city devoid of public transit, there is actually a pretty useful and functional lightrail system in place. It’s great for exploring. If I had to recommend a random stop, it might be Mariachi Plaza.
