This is a small, vivid blue lake that only shows up after heavy rain or snowmelt, and it disappears just as quickly (after a few days).

It’s incredibly beautiful, but also challenging to get there.

It’s an 8.4km return hike (allow 4-5 hours), rough and steep in sections, with massive boulder fields and barely any signage. Check the route here. 

So, not recommended for beginners. But if you’re experienced and love a challenge, it’s a truly special hike worth doing if you’re in the area at the right time!

WHAT TO EXPECT

• No signage, it’s an unofficial trail, so it feels more adventurous

• Mix of forest, boulders, and alpine terrain

• Multiple boulder fields including the famous “Potato Field”

• Track can get muddy or icy depending on the weather

• No signage at the Tarn turnoff, be careful when coming back

• No swimming allowed (it’s a protected catchment area)

• Very limited reception and no facilities

• No pets allowed

TO ACCESS

• Free to access, but come prepared, this is serious bushwalking

• Trailhead at The Springs on Mount Wellington (30 mins from Hobart)

• Follow Snake Plains Track toward the Potato Field

• Best time to go is after heavy rain or snowmelt
