The National Mall is the central strip of D.C., where most of the major sights are lined up. You can stroll past the Smithsonian museums — like the National Museum of American History — and pop into the National Gallery and its Sculpture Garden. Monuments and memorials are scattered along the way, from Lincoln and Roosevelt to the Vietnam and Korean War memorials.

Georgetown feels like a little world of its own in D.C., with cobblestone streets, old brick buildings, and a mix of shops and restaurants. You can wander along M Street and Wisconsin Avenue for over 450 options — from coffee shops to trendy boutiques — or grab a bite along the waterfront. It’s a popular spot for students and visitors alike, and walking through the neighbourhood gives a real sense of the city’s history.

The Solitary Islands Marine Park is the third largest marine protected area in New South Wales, covering a total area of 71,000 hectares and stretching along 75 kilometres of coastline from Coffs Harbour north to the Sandon River mouth. The park is home to an incredible diversity of marine life, including tropical, temperate, and sub-tropical species of fish, coral, and algae, making it a major attraction for divers. Signage throughout the park indicates where specific activities such as diving, fishing, and collecting are permitted. Within its boundaries, the marine park includes tidal waters, estuaries, beaches, and headlands, all protected by a special zoning scheme designed to conserve fish habitats and preserve the area's natural beauty.
