Sydney + Australia in 3 Days on a Budget
Three days: Sydney, the Blue Mountains, and Royal National Park by ferry
Three days adds a second day trip to the same spine as the 2-day version : still one day on the harbour, still the Blue Mountains by train, plus a full day at Royal National Park, reached by train and a short ferry rather than a car. Both day trips together cost under $40 return in transit fares, nowhere near what a single guided day tour charges. Add a fourth day and this becomes the 4-day plan , which folds in Hunter Valley.
Book these before you go
- Check Sydney hotel rates near Central Station on Booking.com; all three days on this itinerary start from there.
- Book a Blue Mountains day trip including Scenic World on Viator if you’d rather not manage the train yourself.
- Rent a car through Discover Cars if you’d rather drive both day trips instead of relying on trains and a ferry.
| Day | Focus | Distance / train time | Cost |
|---|---|---|---|
| Day 1 | Sydney harbour: Circular Quay, Opera House exterior, Harbour Bridge walk, Manly ferry | Home base | Ferry $8.39 each way |
| Day 2 | Blue Mountains: Echo Point, Three Sisters, Scenic World | ~2h by train from Central | ~$19 return train + $55 Scenic World pass |
| Day 3 | Royal National Park: train to Cronulla, ferry to Bundeena | ~1.5h door to door | ~$9.40 each way ferry + normal train fare |
Day 1: Sydney harbour, kept simple
Base yourself near Central Station; both day trips leave from there, and a beachside hotel adds real transit time to every morning. Walk Circular Quay and the Opera House forecourt, free to wander though the interior needs a paid tour or performance ticket, cross the Harbour Bridge on its free pedestrian walkway, and take the Manly ferry, a flat $8.39 fare that beats a paid harbour cruise on value.
Day 2: the Blue Mountains, DIY
Trains on the Blue Mountains Line leave Central roughly hourly for the two-hour ride to Katoomba, around $9.55-9.65 one-way on Opal or contactless. Walk to Echo Point in Blue Mountains National Park for the Three Sisters, then Scenic World for the Railway, Skyway, Cableway and Walkway, about $55 adult on the Unlimited Discovery Pass. See the full Blue Mountains price rundown for every ticket broken down.
Day 3: Royal National Park, by train and ferry
Take the train to Cronulla, then the Cronulla Ferries service to Bundeena, about $9.40 each way and paid in cash or by card on board, not with Opal. Door to door it is roughly 1.5 hours from the city. From Bundeena, walk part of the Coast Track inside Royal National Park , sandstone cliffs, ocean lookouts, and a couple of good swimming spots at Little Marley and Wattamolla if you have the legs for the extra distance. There’s no food service on the track itself, so carry water and lunch.
Is Royal National Park worth a second day trip, or should I stay in the city instead?
Worth it, mainly for the price: a Bundeena return costs under $20 combined in ferry and train fares, and the Coast Track’s ocean views rival anything on the Bondi to Coogee walk without the crowds. Skip it only if a full day of walking doesn’t appeal, in which case swap in a second, slower day around Bondi and Coogee instead.
Do I need a car for either of these day trips?
No. Both the Blue Mountains and Royal National Park are built for exactly this train-and-ferry combination; a rental car only starts paying off once Hunter Valley enters the itinerary, since public transport there turns into a three to four and a half hour slog each way.
Three days and two day trips for under $40 combined in transit fares is the real budget case for basing yourself in Sydney rather than picking one region and staying put.
