Sydney's harbour does most of the work, and the city knows it: half the population seems to be swimming, running or catching a ferry across it at any given moment. The famous pair of landmarks are worth the fuss, but the better days here are cheap ones — a coastal walk, an ocean pool, a ferry at dusk. Two hours west, the sandstone country of the Blue Mountains is close enough to be a day trip and good enough to deserve longer.
Getting Around
Tap on and off with a contactless card across trains, buses, ferries and light rail; there are daily and Sunday caps
The Manly ferry is the best value sightseeing in Australia — a full harbour crossing for the price of a bus fare
Trains from the airport are quick but carry a steep station access fee; a bus to a nearby station avoids it
Central station serves the Blue Mountains line, about two hours to Katoomba
The eastern beaches are reached by bus from the city in 30-40 minutes
Sydney
The Opera House — worth the tour, and free to walk around; the steps at dusk are the photograph
Harbour Bridge — the BridgeClimb is expensive, the Pylon Lookout is cheap, and walking across it is free
Bondi to Coogee coastal walk — 6km of clifftop path past beaches and ocean pools, about two hours
Bondi Icebergs — the ocean pool at the end of the beach, open to anyone for a few dollars
Royal Botanic Garden and Mrs Macquarie's Chair, for the classic view of both landmarks together
Watsons Bay and the Gap — ferry out, cliffs and fish and chips
Newtown and Surry Hills — where the city eats and drinks away from the harbour
The eastern beaches walk, easily the best free thing in the citySandstone ledges along the way, with the next beach across the bayThe walk stays on the cliff edge almost the whole way
The Blue Mountains
The mountains are really a sandstone plateau cut by deep valleys, and the blue haze that names them comes from eucalyptus oil in the air. Katoomba is the base, reachable by train from Central without a car, which makes this one of the easiest big day trips anywhere. It's also several degrees cooler than the coast and can be wet when Sydney is clear, so pack accordingly.
Sandstone escarpment and forest, a short walk from the lookouts
Three Sisters at Echo Point — the view everyone comes for, free and a short walk from Katoomba
Giant Stairway — around 900 steps down into the Jamison Valley, knees permitting
Scenic World — the steepest passenger railway in the world, plus a cable car, for getting back up
Wentworth Falls and the National Pass — the finest walk in the mountains, cut into the cliff face
Blackheath and Govetts Leap — quieter lookouts with equally big views
Leura — a village of tea rooms and gardens, ten minutes from Katoomba
Check the NSW National Parks site for track closures and fire danger before you go

Where to Eat and Stay
Brunch is taken seriously, and the coffee is as good as Melbourne's whatever either city claims
Sydney Fish Market for seafood, and the Asian food in Chinatown, Cabramatta and Eastwood is excellent
Surry Hills and Newtown for dinner; Bondi for a beach day that turns into an evening
Stay in Surry Hills or Newtown for value and food, Bondi for the beach, the CBD for transport
Katoomba has hostels and old guesthouses if you'd rather stay in the mountains than day-trip
Take the Manly ferry at sunset. It costs the same as a bus ride, passes the Opera House and the bridge, and beats every paid harbour cruise in the city.
