I want to visit from the States. I'm afraid to try driving on the opposite side of the road. So how could I get transportation from an airport to here? And are there any taxis in Dogellau for short trips? If I could figure out transportation, I would book a trip.
You can get a train from London and Birmingham to Machynlleth or Barmouth and a taxi from there.
Trains and buses are very easy to manage, and yes, Dolgellau has a taxi service. The gentleman who took us to Tyddyn Mawr mentioned that the next day he was spending the entire day doing a private tour with a foreign family. Don't let lack of transportation put you off - it is well worth the adventure.
