Second Valley is a coastal town on the Fleurieu Peninsula in South Australia.
The name is derived from being the next valley north of Rapid Bay, the initial camp on South Australian mainland of Colonel William Light.
An excellent base for the tourist is the Second Valley Caravan Park, located only metres from the beach and jetty at this popular coastal township. The park has 51 powered sites, and 21 unpowered campsites, together with all the facilities to ensure a pleasant stay.
There is an abundance of trees, a pergola area with outdoor settings, and two large covered gas barbeques for the free use of guests. The laundry contains an automatic washing machine and clothes dryer, and there is a shower block and amenities block.
