Located on the southern tip of Botany Bay, Kurnell snorkeling spot allows the exploration of a unique underwater world, made of seaweed and seagrass. While this environment is well known for hosting seahorses and seadragons (they are nevertheless difficult to spot while snorkeling), Kurnell has even more surprises to offer! While swimming along the shore, you may come across colorful wrasse, octopuses huddled among the rocks, and, sometimes, a stingray resting on the sand.

How to get to Kurnell snorkeling spot?

Kurnell is a small suburb in Sydney, on the southern tip of Botany Bay. From Central Sydney, you can reach Kurnell by car (a route of around 22km) or by public transportation (take a train to Cronulla, then the bus 987-Cronulla to Kurnell “Loop Service” to Kurnell beach).

Once you’re in Kurnell, walk towards north along the beach until you arrive at James Cook landing place, located in Kamay Botany Bay National Park.

Water entrance for snorkeling Kurnell

There are several possibilities to enter the water, both on the south and on the north side of the pier (see the map). A few patches of sand between the rocks allow you to dive into the water without stepping on the rocks.

Kurnell snorkeling exploration

The snorkelling area encompasses the rocky shoreline which stretches on either side of the monument and the pier. From the shore, the seabed gently slopes down, allowing you to observe the underwater life at low depth.

Australian stripey in Kurnell
The stripey is one of the most common fish you can spot when snorkeling Kurnell.

The seafloor alternates rocks, sandy areas and a wide diversity of seaweed (↕2-10ft/0.5-3m). In Kurnell, in particular, you will find beautiful stretches of Neptune’s necklace (Hormosira banksii), paddle weed (Halophila ovalis), patches of kelp, as well as beautiful, almost fluorescent, blue branching seaweed (Fauchea laciniata).

In the area, you may spot urchins, sponges, limpets, and other small shellfish attached to the rocks. These areas are also suitable for observing octopuses, whose fishing is banned on this part of the shoreline.

Octopus in Kurnell
Have a look in rocky holes and cracks: you may spot an octopus here, as they are protected in the area.

Kurnell is a spot well known for hosting sea horses and the legendary weedy seadragon, but finding them is a real challenge, especially in shallow areas.

However, you will easily spot stripey, mado, senator wrasse and snakeskin wrasse. Where the rocks make room for stretches of sand (↕6-10ft/2-3m), you might also come across an Australian stingray resting peacefully on the seabed.

Restaurants in Kurnell

On the edge of the park, there are several cafés and restaurants, especially along Captain Cook Drive. The closest (Endeavour Coffee and Ice Cream and Kurnell 1770 Bakery and Café) are located 300m by foot from Captain Cook monument.
