Overview

Tucked beside Welcome Flat Hut at the end of the Copland Track, these natural hot pools are the bullseye reward: warm, silty basins ringed by mountains. It’s a classic West Coast backcountry vibe—minimal infrastructure, maximum scenery—and the pools sit just a short walk from the hut.

What You'll Experience

  • Warm, shallow pools with muddy/gritty bottoms and varying temperatures.
  • Big alpine views and starry night skies if you soak after dark.
  • A mellow post‑tramp ritual: drop your pack at the hut, wander a minute or two, and slide into the water. At busy weekends and holidays the pools can feel social, but it’s easy to find a quieter corner at off‑peak times.

Geology, Plain English Version

These springs aren’t volcanic. Groundwater circulates deep along fractures tied to the Southern Alps/Alpine Fault, heats up, then returns to the surface near Welcome Flat. Floods and seasonal shifts can reshape the basins, so pool depth and clarity change over time.

Safety and Etiquette

  • DOC asks you not to use soap or shampoo in the pools.
  • Keep your head above water to reduce the risk of amoebic meningitis.
  • Expect sandflies—cover up and use repellent.
  • The Copland Track is subject to heavy rain, slips, and flooded side streams; closures can happen at short notice. Check conditions with DOC before you go.

Wildlife Notes

You may hear kea higher up the valley; they’re often active around the Copland car park—don’t feed them and secure any loose items. On the short walk to the pools, you might spot glow worms after dark.

Best Time to Visit

  • Season: Summer and autumn are the sweet spot. Winter and spring bring avalanche hazards in the valley and surrounding slopes.
  • Day/time: Soak at sunrise or after sunset for fewer sandflies and softer light. Weekdays are typically quieter than weekends and holidays.

Trip Logistics

  • Reached via a full‑day tramp each way on the Copland Track; the route includes swing bridges, muddy and bouldery sections, and active landslide areas.
  • Bookings are required year‑round for Welcome Flat Hut (and the Sierra Room if you want extra comfort). Toilets are at the hut and shared with the adjacent campsite.
  • No phone service for most of the walk—go prepared, and always check the latest DOC alerts before departing.

Pros

  • Natural, soothing pools with big alpine views
  • A short stroll from Welcome Flat Hut after the hike
  • Several pools with different temperatures

Cons

  • Sandflies can be intense around the river and pools
  • Keep your head above water due to amoebic meningitis risk

Tips

  • Pack strong insect repellent and cover up around dusk to beat sandflies.
  • Soak at sunrise or after dark for quieter pools and great night skies.
  • Bring lightweight sandals for the silty, gritty pool bottoms.
  • Book the hut well in advance; the Sierra Room is a separate, sole‑occupancy option.
  • Check DOC track alerts before you go; closures can occur after heavy rain.
