Once you are in Cronulla, the shops, North and South Cronulla Beaches, and Gunnamatta Bay are within walking distance of the accommodation spots and the train station. The north end of Cronulla mall aligns with North Cronulla Beach, the centre Surf Road aligns with South Cronulla Beach. The far southern end of the mall, past the station, is Gunnamatta Bay.
Walking 1km along the beach esplanade northwards will get you to Eloura Beach and a further 1km will get you to Wanda Beach. Walking southwards along the ocean will get you to Shelly Beach and then Bass and Flinders Point.
You can drive and park within Cronulla, but parking can get difficult during summer, especially if there is a surf carnival on, or on a sunny summer weekend, and especially at South Cronulla beach.
There are buses from Cronulla and Caringbah stations that service surrounding areas [http:/www.connexnsw.com.au]. They will get you closer to the Eleura or Wanda beach than the train does. The catch is that they run infrequently, every hour or so on weekdays, and every couple of hours on weekends. They also wander around the area rather than travelling directly, taking around half an hour for the trip.
Taxis are available at the station.
