Summer (December-February) and shoulder months fill up fastest, especially the TranzAlpine train and full-day West Coast tours. If you're flexible, autumn and spring offer fewer crowds and often just as good weather - check before you go for seasonal closures on specific tracks.

A full day covers the main sights well - you'll see Punakaiki Rocks, do a gorge walk, maybe squeeze in a train journey or guided tour. If you're using Greymouth as a jumping-off point to Franz Josef or Christchurch, one overnight is realistic.

Tours depart from Greymouth daily, so you don't strictly need to self-drive. That said, having a car gives you flexibility to explore between bookings and reach some trailheads independently.

Most include transport between major sites like the gorge and Pancake Rocks, guided walks, and sometimes a gold panning or tasting experience. Lunch and entry fees vary - check the specific tour details before booking.

E-bike tours suit families with school-age kids who can pedal; younger children may struggle with distance. Tree-top walkways are accessible for all ages. For any specific accessibility needs, contact the tour operator ahead of time.

Book at least a week ahead during peak season; it's one of the region's most popular single experiences and can sell out. Shoulder seasons are more flexible - aim for 3-5 days minimum.
