Yarrangobilly Caves thermal pool, Australia

What it is

Yarrangobilly Caves thermal pool is a spring-fed swimming pool in the Yarrangobilly area of Kosciuszko National Park. NSW National Parks describes it as a natural swimming spot fed by a spring that keeps the main pool at a constant 27°C year-round, an unusual comfort in a high-country river valley. The main pool overflows in a small cascade into a separate children’s wading pool, which makes it feel more like a built swimming hole than a random bend in the river.

What makes it distinct

It’s the combination that sells it: clear mountain air, a reliably warm pool, and a genuine national park setting that still has basics like nearby picnic tables, toilets and change rooms. In summer it works as a quick swim stop. In cooler months it’s one of the few places in the Snowy Mountains where you can float in warm water without booking a spa.

The trade-offs

Access is short but steep, and the pool is popular. If you want solitude, come early, and treat it as a shared swim rather than a long private soak.

Where it is

The thermal pool sits below the Yarrangobilly Caves precinct in Kosciuszko National Park. NSW National Parks lists the visitor centre address as 50 Yarrangobilly Caves Road, Yarrangobilly, and the pool is reached from that area via the signed thermal pool walk. Park entry fees apply in the Yarrangobilly area, so plan for a vehicle day fee unless you already hold a relevant pass.

How to get in

Access is via the short but steep thermal pool walk, or by linking it into the Yarrangobilly River walk. On the ground that means you budget for a downhill walk to start, then a steady climb back out. The path can feel slippery after rain or frost, so sturdy shoes and a slow pace help, especially if you are carrying towels and kids’ gear.

What to bring

Bring swimwear, a towel, water, and footwear with grip for the track and wet pool edges. In cooler weather, add a warm layer for the walk back up. Keep snacks simple and eat at the picnic area rather than near the water. Check current alerts before you drive in, fire bans and planned events can change the day.

Who it suits best

This is a good fit for families and mixed groups who can handle a short steep walk and want a reliable warm swim. The separate children’s wading pool is helpful for small kids, but you still need close supervision because the setting is natural and surfaces are wet. For adults, it’s an easy “reset stop” between cave tours, picnics, and short walks.

Mobility and access reality

NSW National Parks notes access is via a short but steep walk and suggests contacting the visitor centre if you have accessibility needs. That is the key point: do not assume step-free access. The route involves a descent and climb, and the pool edges and entries are not described as ramped. If you need wheelchair access into the water, this is unlikely to be comfortable or safe without prior planning and support.

Expectations vs reality

It looks like a remote hidden pool in photos, but it runs like a popular park attraction. Expect other swimmers, especially in warm weather and school holidays. The best experience usually comes from a shorter swim, a dry-off in the sun, then moving on rather than trying to “own” the warmest corner for an hour.

Heat and cold, both matter

The pool is warm (27°C), but the surrounding air can be cold, especially in winter. Plan your exit so you do not stand around dripping in wind. In summer, warm water plus sun still dehydrates you, so drink water between dips and take breaks out of the pool.

Slips and steep-track management

The most common problem here is a slip, either on the steep track or on wet edges. Wear shoes with grip on the walk, take your time on the return climb, and keep your hands free. If you are carrying children, slow down more than you think you need to.

Etiquette that keeps it pleasant

Give people space, especially near the narrow entry points and the wading pool. Keep noise modest, skip soaps and shampoos, and leave the water as you found it. Photos are fine, but keep them focused on your group. If the main pool is busy, rotate in and out after a reasonable time. It goes best when everyone shares the warm water and moves along.

Leave-no-trace without drama

Use the toilets and change rooms, bin your rubbish if there is room, and pack it out if bins are full. Small habits keep this spot usable for the next group.

Is there an entry fee?

The pool itself is not ticketed, but NSW National Parks states park entry fees apply in the Yarrangobilly area (a vehicle day fee unless you have a relevant pass). Check the official NPWS fee page and current alerts before you go.

How warm is the water?

NSW National Parks states the pool is permanently heated to 27°C by a natural spring, year-round.

How hard is the walk?

NSW National Parks describes access via the short but steep thermal pool walk. Treat it as a brief downhill and a more noticeable climb back out, especially with wet gear.

Is it good for kids?

Yes, with supervision. NSW National Parks notes the main pool overflows into a children’s wading pool, which helps families, but wet surfaces and shared space still require close attention.
