我们是开车去的，没有经历过汽车。但是从慕尼黑乘火车来的游客都在菲森转汽车。我替你在网上看了一下2019 的info， 见内。

From Füssen, use bus 73 (direction Steingaden / Garmisch-Partenkrichen) or bus 78 (direction Schwangau) and exit at stop Hohenschwangau – Alpseestraße. These buses are generally marked Königschlösser (Royal Castles). Tickets are available from the bus driver, or included in the Bayern Ticket (but not in normal train tickets or the Allgäu-Schwaben Ticket).
