NSW TrainLink services run from Central Station to Katoomba roughly every 30 minutes to an hour, taking around two hours through the Blue Mountains foothills. The train itself is part of the appeal: the last stretch climbs steadily through eucalypt forest before opening onto the plateau at Katoomba, noticeably cooler than the harbour city below. Late August sits at the tail end of the Southern Hemisphere winter up here, and mornings can be genuinely cold, colder than anything the marathon weekend delivered in Sydney itself.
Katoomba works as a base for the region's best-known sights without demanding much walking on arrival day. The town itself has cafes, pubs and a handful of art deco buildings worth a slow look, and the main attractions are a short bus or taxi ride rather than a hike from the station.
The mountains reward a second day more than a rushed first one. Treat the evening of arrival as recovery: a short walk to a lookout, an early dinner, an early night. Save the more demanding tracks for the following morning, once legs have had a full night to settle after the marathon.
Echo Point and the Three Sisters
Echo Point, a short bus ride or 20-minute walk from Katoomba station, gives the classic view of the Three Sisters rock formation and the Jamison Valley beyond. The lookout itself is flat and paved, accessible without any real exertion, which makes it the right first stop on the evening of arrival. The stepped Giant Stairway descent into the valley from here is the serious option, over 800 steps down into rainforest, and is better attempted the following morning than on the day of arrival.
Scenic World
Scenic World, on the edge of Katoomba, runs a cableway, a railway and a walkway through the Jamison Valley without requiring the stair descent. The Scenic Railway, the steepest passenger railway in the world, drops into the valley at a sharp angle; the Skyway cable car crosses above it with views to the Three Sisters and Katoomba Falls. This is the practical way to see the valley floor on legs that are not ready for 800 steps.
Leura village
Leura, one stop before Katoomba on the same rail line, is the quieter, more polished of the two mountain towns: a single main street of cafes, bookshops and gardens, with the Gordon Falls and Leura Cascades reserves a short, flat walk from the centre. It suits a slow morning better than Katoomba's busier tourist strip.
Getting back
Return trains to Central run on the same roughly hourly schedule throughout the day. Allow the full two hours plus a margin for weekend engineering works, which NSW TrainLink schedules periodically on this line.
