Combining a man-made pool with a naturally fed spring, the Yarrangobilly Caves Thermal Pool has become the main attraction in Australia’s Kosciuszko National Park. The perfect place to relax after a long bushwalk, visitors can enjoy the pool’s warm waters.
Sitting along the edge, the pool is backdropped by an impressive forest with hiking trails, caves, and picnic areas. Nestled in a valley of eucalyptus trees, the pool is close to the Yarrangobilly River. With much warmer water than the river, the thermal pool is suitable for swimming all year long.
Somewhat remote, the hike to the Yarrangobilly Caves Thermal Pool is challenging but doable for most tourists. The walk to the pool takes about 35 minutes and it is very steep. Additional attractions near the thermal pool include caves, river, and various trails.
Emerging from the forest, the thermal pool feels magical with its deep blue hue and balmy water. When combined with a picnic, visitors can easily spend the day lounging poolside while enjoying time in the great outdoors.
Mineral Thermal Pool
The Yarrangobilly Caves Thermal Pool is naturally fed by an underwater spring that is located about 0.6 miles (1km) underground. Bubbling to the surface, the temperature of the water is a perfect 80.6°F (27°C) all year long. Featuring one large main pool, a shallower pool at the end is perfect for visiting youngsters and families.
As the subterranean water travels to the surface, it is mildly mineralized by the rocks and soil. Minerals that are found in the water of the thermal pool include magnesium, calcium, sodium, as well as a little calcium carbonate.
There are technically two thermal pools at the Yarrangobilly Caves. However, they are connected and use the same thermal water. The first pool is 65.6 feet long (20 meters) and 8.2 feet (2.5 meters) deep. As the largest pool, it is suitable for adult swimmers. It is normal for a layer of algae to grow on the sides of the large pool and it is not harmful to swimmers.
At the end of the large pool is a smaller wading pool for children. Water from the large pool flows into the children’s pool to ensure that it also maintains a consistent temperature throughout the year. Swimmers can use ladders to access the larger pool, while the shallower pool is just a few feet deep to ensure that it is safe for wading children.
Even though the thermal pool is man-made, the water is very natural as it flows from underground through the pools and to the Yarrangobilly River. Although the pool is regularly cleaned by park rangers, the water is never treated with chemicals. It is common to spot Eastern Banjo Frogs in the pool. The frogs can secrete poison when touched, so it’s best to leave them alone.
Surrounding the pools are a grassy hill and a large lawn. The flat grassy areas are perfect places to lay down a picnic blanket. There are also a few picnic areas around the pool with tables and benches. Nearby trees provide shade during the hot summer months.
In addition to the picnic area, facilities at the Yarrangobilly Caves Thermal Pool include changing rooms and toilets. There are also trash cans throughout the area, so people won’t have to pack out any garbage.
Currently, the pool is not handicap accessible. The walkway to get to the thermal pool from the parking lot is very steep, but well-maintained. Visitors will have to walk 0.43 miles (0.7km) to get to the thermal pool along a wide, dirt road. The trip down to the pool can be just as difficult as the trip up because of the steep grade.
Depending on the hiker, most people will be able to reach the pool in 15-30 minutes of walking. The trail is very clearly marked, so visitors won’t have to worry about getting lost in the surrounding bushland. Visitors who would like to avoid the steep walk back to the parking lot can loop back to their car by taking the Yarrangobilly Caves – River Walk instead.
