Ewens Ponds

Moderate risk: Cold Water Hypothermia

Consistent water temperature of 15°C (59°F) year-round. A full-length wetsuit is mandatory; gloves, hood and boots strongly recommended. Even in summer the cold can quickly exhaust swimmers.

Moderate risk: Annual Seasonal Closure

The ponds are closed annually for snorkelling and diving from 1 September to 30 November to protect unique plant life.

Moderate risk: Cold water temperatures

Average water temperature is 10–15°C year-round; full-length wetsuits are mandatory to prevent hypothermia.

Moderate risk: Catastrophic fire danger closure

The park closes on days of Catastrophic Fire Danger and may close on Extreme Fire Danger days. This risk is highest during the dry summer months.

Moderate risk: Low Water Levels

Water levels can drop due to reduced groundwater inflows, occasionally forcing additional closures. Monitor park website before visiting.

Moderate risk: No Lifeguards / Remote Location

No on-site supervision. The ponds are in a remote conservation park with limited phone reception. Snorkel with a buddy.

Moderate risk: Seasonal Pond Closure

The ponds are closed annually from 1 September to 30 November for aquatic vegetation regeneration. No snorkeling permitted.

Moderate risk: Strong downstream current

The constant flow from the pond outflows creates a steady current that can sweep snorkelers downstream faster than expected, especially after rain.

Moderate risk: Cold freshwater temperature

The limestone-fed spring water remains very cold year-round (12–15°C), increasing the risk of cold shock and hypothermia without a wetsuit.

Low risk: Current in Connecting Channels

A gentle but persistent current flows through the narrow channels connecting the three ponds, pushing snorkellers from Pond 1 towards Pond 3.

Low risk: Deep Pockets & Cave

The third pond reaches 13 metres depth and contains a small cave. Snorkellers may inadvertently descend beyond safe breath-hold limits.

Low risk: Annual closure period

The ponds are closed for snorkelling and diving annually from 1 September to 30 November (inclusive) for environmental protection.

Low risk: Permit-only entry

Snorkelling requires a pre-booked one-hour time slot permit; entry without a permit is prohibited. Maximum two sessions per person per day.

Low risk: Annual Vegetation Closure

Ponds are closed annually from 1 September to 30 November (inclusive) to allow aquatic vegetation to regenerate after summer pressure.

Low risk: Cold Water Temperature

Spring-fed water remains cold year-round (12–14°C). A thick wetsuit (5mm+) is strongly recommended to prevent hypothermia.

Low risk: Current in Connecting Creeks

A gentle current flows through the channels connecting the three ponds. Drift snorkelling is the norm, but care is needed to avoid being swept downstream.

Low risk: Permit and time-limited sessions

A pre-booked permit is required; only one-hour time slots are available. You must exit by the end of your slot. Snorkellers must enter at Pond 1 and exit at Pond 3 — no out-and-back swimming is permitted.

Low risk: Buddy system required

You must snorkel with a buddy and complete an online indemnity form before entering the water.

Low risk: One-Way Route Only

Snorkelers must enter at Pond 1 and exit at Pond 3. Exiting at the wrong pond means a 1 km walk back along the roadside.

Low risk: Limited visibility in creek sections

While the ponds are famously clear, narrower sections of Eight Mile Creek can have reduced visibility due to vegetation and sediment.

Low risk: Seasonal closure for conservation

The ponds are closed annually from 1 September to 30 November for ecological protection.
