Torre Grande is a nice smaller town. There weren't many tourists. Every night there was something going on (Sardinian, Latin American festival, stalls with food and souvenirs, live music...). A lot of restaurants, small shop, bakery and ice cream shops.
We mostly used Torregrande as a base to explore the areas around Oristano and Cabras. The beach is large and has some bars, but dogs are not allowed. The dog beach is at the far end of the village beyond a dirt parking lot, abandoned beach bars and derelict industrial buildings. Not particularly welcoming. There are some good restaurant in the town. Overall Torregrande is quite easy to reach and to travel around (with a car), so a good base to explore the area.
Sand beach with smooth sand, beach bars/restaurants, sports activity at one club on beach. Garbages on beach and its entries, mosquitoes when sunset due to close rice fields. Need to use repelents and it's enough.
