I've been reading about Tresticklan National Park and I'm thinking of visiting - but I'd be staying in either Oslo or Gothenburg and relying on public transport. I understand that the nearest railway station is at Ed, but I'm uncertain how much further north the Tresticklan Park is located. Could I arrive in Ed at around 9.00 in the morning, walk in the park, then get back to Ed by 4.00 p.m.? Or is the park too far north? (I'm assuming buses don't run in the countryside.)
Another question: Is there such a thing as a Return rail ticket on SJ? Their website only seems to give details of single-tickets (one ticket for each direction of travel). Or am I just being stupid?
