Could you please advise if you are close enough to walk to Tranz Alpine Station and if not are you aware of approximate taxi cost.
We had a rental car at the end of our trip in Greymouth and returned it to the station just before we caught the train. I would suggest its to far to walk with luggage. No idea what a taxi would cost.
It is about a 20 minute walk to the station. We caught a taxi (had too much luggage to walk there) and it cost us NZ15$. The exchange rate is almost 1 for 1.
Enjoy your holiday
It is about 1.3 mi. (2 km.) from the Gables Motor Lodge to Greymouth Station, so a long walk, especially with luggage. The owners of the Gables are incredibly accommodating, so I'm sure they could arrange transport.
Email Gable Lodge who will give you the information you require. I do think it too far to walk with luggage unless backpacking. Maps Google shows it is 2.1km. Walk to Monteiths Brewery is okay. We had hire car so not doing railway the last time.
It's not far to walk but if you have baggage that could be a problem. A taxi wouldn't cost much. Is the TransAlping operating? It wasn't when I was there in February.
