People have been enjoying the mineral-rich, naturally filtered waters of this hot spring since 1895. In the past 130 years or so, an impressive complex has grown up to take full advantage of these waters, including an Olympic-sized pool, children’s “hydroplay” area, a wellness centre, gym, and a day spa attached to the baths.

Located on the fringes of this opal mining town, these pleasant pools are considered to be some of the finest of the state’s naturally heated baths. Which makes the fact that they are both free to access and open 24 hours a day even more remarkable. Percolating through the area’s unique geology (one of only a handful of places in the world where black opals can be found), the water in these bore baths takes almost two million years to reach the surface.

There’s something faintly surreal about encountering this spring-fed pool, nestled in a quiet valley clearing within Kosciuszko National Park. It draws its waters from a reservoir over a kilometre beneath the ground. Warmed to a balmy 27 degrees, this gently mineralised hot spring pool can either be accessed from a nearby carpark, about 700 metres stroll away, or you can make it your reward for completing the three-kilometre River Walk hike.

At the Burren Junction campgrounds, the artesian waters of the bore baths are a delightful 41 degrees all year round. Aside from your $5 camping fee, access to the baths is absolutely free and they’re open 24 hours a day.

Using naturally mineralised water drawn from underground springs, the heated baths are infused with herbal treatments to soothe aching muscles and energise the soul. For the ultimate pampering, massages, skin treatments, and private baths are also available, and you can even stay in traditional Japanese accommodations on site if you want to make a weekend of it.
