The water around Sardinia is crystal clear and is perfect for diving. Dive down beneath the surface and explore the marine life together with wrecks dating from Roman times as well as both World Wars. Located within the Marina of Porto Conte is an exclusive diving centre, Diving Porto Conte, which has 300 berths. Facilities here include a pizza restaurant and bar, well-equipped bathrooms and hot showers, and ample parking spaces.

The imposing 16th-century walls that surrounded the city are still largely intact, and provide a stunning backdrop to the whole city, especially along the seafront. The ramparts, called bastioni, house numerous restaurants, bars, cafes and shops, which are great for a drink at sunset in the evening breeze.

Sustainable tourism is not only about being environmentally friendly, but also about respecting the cultural heritage of the destination. In Canberra, you can immerse yourself in one of the oldest and richest cultures in human history. Appreciate the Aboriginal and Torres Strait Islander art and traditions at the National Gallery of Australia, Burrunju Art Gallery and Aboriginal Dreamings Gallery. Take a tour with a local Ngunnawal elder with Dhawura Tours or try your hand at traditional First Nations practices at a workshop at the National Arboretum.
