Getting Around Greymouth: What Actually Works
Greymouth is a working town first and a tourist stop second, which means a lot of the usual travel advice doesn't apply here. The main street, Fox Terrace, runs along the waterfront. That's where you'll find fuel, a few cafes, and the visitor centre if you need basic maps or weather updates. Beyond that, the place sprawls a bit along State Highway 6, and most of the useful services are split between the northern and southern ends. I've been going through here since the late nineties, mostly on road trips up and down the west coast and a couple of times for work. The first thing you need to understand is that Greymouth isn't particularly well signposted for anything that isn't on the highway. If you're trying to get from the bus stop to the hospital, for instance, it's about a ten minute walk and the route isn't obvious unless you know it. I learned that the hard way once with a rental car and a full bag of groceries during a rainstorm. I just walked instead.
Greymouth New Zealand logistics and practicalities
The Grey District Council website has some information but it's not great for visitors. The regional council covers a much larger area and their maps are more useful for backcountry stuff. For everyday things like ferry times to the nearby islands or bus routes through the district, call ahead. Most places on the west coast don't have real-time online updates for public transport, and the bus service is basically once or twice a day depending on when you're traveling. Ferries leave from Greymouth for the Paparoa area, but they're seasonal and weather dependent. The operator usually cancels on short notice if the river conditions are rough. I've been stuck waiting at the wharf for an hour only to get a text that it was canceled, so don't plan your whole day around a ferry booking without having a backup. The train museum is worth a look if you're into that sort of thing, and it's within walking distance from most of the central accommodations. One thing people don't always factor in is the river. The Grey River is massive and prone to sudden flooding, especially in autumn. If you're doing any walking or driving near the riverbed or the estuary, check the MetService forecasts for the West Coast before you go. Flood warnings can come up with very little notice and roads can close without much advance warning either.
Accommodation realities
There are a handful of motels and a hostel in town, plus some holiday parks on the outskirts. Book ahead in summer and during school holidays. The town swells noticeably when tourists show up for Franz Josef and Hokitika, and the limited options fill up fast. I've had to drive to Hokitika for a place to stay on two separate occasions because everything was booked. The motel strips outside the central area are fine if you're passing through. They're older properties but generally well maintained. The ones right on Fox Terrace are more expensive and louder, which matters if you're a light sleeper. SH6 traffic doesn't stop at midnight.

What to actually do here
Most people use Greymouth as a base for day trips rather than a destination itself. The Punakaiki Pancake Rocks are about forty minutes south. Paparoa National Park has cave tours that run year round but book ahead in peak season. The glacier towns are further south and the drive takes time because the road is narrow and one lane in sections. If you have a day to spare in town, the gold mining history is genuinely interesting. The nearby fields produced some of New Zealand's richest gold deposits and there are old sluice remnants you can walk to from several points along the river. It's not curated or touristy. You just walk and look. The local i-/site at the visitor centre has current information on track closures, weather warnings, and ferry schedules. Go there first thing when you arrive. It'll save you a few mistakes.
