Innes National Park is a beautiful national park set at the southern point of the Yorke Peninsula. The beautiful coastal landscape and gorgeous bays and beaches make it a wonderful place to visit. There is a small entrance fee into the park, although it is definitely worth it. The far tip is marked by Cape Spencer, and the two main settlements near the cape include Pondalowie Bay and Stenhouse Bay (which is just outside the park).
Pondalowie Bay has a large lobster fishing industry, as well as being a good swimming and surfing beach. The only other swimming beach in the area is Browns Beach, as all of the other beaches are too dangerous to go swimming.
There are also two historic sites within the park that you should visit. Just past Cape Spencer you can go to the ruins of an old mining community called the Inneston Historic Site. You can also see the ruins of a 711 tonne ship called Ethel that ran aground in 1904.
It is possible to stay in the park, which is absolutely wonderful, due to the great views you look out upon when you wake up. There are several basic cabins as well as some camping grounds.
