When planning a trip from Sydney, one of the first questions travellers ask is simple but important: How far is the Blue Mountains from Sydney?
Distance directly affects travel time, transport choice, day-trip feasibility, and overall itinerary planning—especially for visitors trying to decide between a quick day tour or an overnight escape.

This guide breaks down exact distances, travel times by car, train, and coach, and explains how distance changes depending on where you’re going within the Blue Mountains region.




1. Why Distance to the Blue Mountains Really Matters​

Understanding distance isn’t just about kilometres on a map—it helps you decide:

  • Whether a day trip from Sydney is realistic

  • What time you need to leave

  • Which transport option suits you best

  • If a guided experience like Blue Mountains Private Tours or Sydney Private Tours will save time and stress
Because the Blue Mountains stretch across a wide region, the distance varies significantly depending on your final destination.




2. Official Distance: Sydney to the Blue Mountains (km & miles)​

The Blue Mountains begin west of Sydney, but most visitors head to Katoomba, the main tourist hub.

Common distance references:​

  • Sydney to Glenbrook: ~60 km (37 miles)

  • Sydney to Wentworth Falls: ~95 km (59 miles)

  • Sydney to Katoomba: ~100–110 km (62–68 miles)

  • Sydney to Blackheath: ~120 km (75 miles)

  • Sydney to Lithgow: ~140 km (87 miles)
This range explains why you’ll see different answers online—the Blue Mountains is a region, not a single point.




3. Driving Distance & Travel Time by Car​

Driving is one of the most popular ways to reach the Blue Mountains.

Typical driving times:​

  • Katoomba: 1.5–2 hours

  • Blackheath: 2–2.25 hours

  • Lithgow: 2.25–2.5 hours

Main factors affecting drive time:​

  • Sydney traffic (especially weekday mornings)

  • Weather conditions (fog is common)

  • Route choice
Most drivers take the M4 / Great Western Highway, which is the fastest and most direct route.




4. Distance & Duration by Train from Sydney​

The Blue Mountains Line runs directly from Sydney Central Station.

Train travel times:​

  • Central → Katoomba: ~2 hours

  • Central → Wentworth Falls: ~1 hour 50 minutes

  • Central → Blackheath: ~2 hours 15 minutes
While the rail distance is similar to driving distance, trains make multiple stops, which slightly increases total travel time. Trains are reliable, affordable, and popular with budget travellers.




5. Public Transport: Bus & Coach Distances​

Coach tours follow similar road distances to cars but usually take longer due to:

  • Multiple pick-ups

  • Scheduled stops

  • Group coordination

Typical coach travel time:​

  • 2–2.5 hours one way
Guided options—including Sydney Private Tours and small-group Blue Mountains experiences—often reduce total travel time by using efficient routing and fewer stops.




6. Straight-Line vs Road Distance: Why It Matters​

You may see references saying the Blue Mountains are only 70–80 km from Sydney—this refers to straight-line (as-the-crow-flies) distance.

In reality:

  • Roads follow terrain and valleys

  • Mountains require winding routes

  • Actual travel distance is longer
For planning purposes, always rely on road or rail distance, not straight-line measurements.




7. How Distance Changes by Blue Mountains Destination​

Here’s a quick comparison from Sydney CBD:

DestinationDistanceTypical Travel Time
Glenbrook~60 km1–1.25 hrs
Leura~100 km1.75–2 hrs
Katoomba~105 km1.75–2 hrs
Blackheath~120 km2–2.25 hrs
Lithgow~140 km2.25–2.5 hrs
This variation is why many visitors choose Blue Mountains Private Tours, which optimise routing based on interests rather than fixed destinations.




8. Best Routes from Sydney to the Blue Mountains​
