Katoomba is nice. Between growing up in western Sydney, and taking friends there, i’ve been a bunch of times over the years. I took my wife, mother-in-law, and a friend up there in July last year. There’s some pictures of the town and the Three Sisters here.
There’s certainly enough to do up there for a day, especially when you consider that you need to factor in about two and a half hours each way for the train. The train trip itself is interesting, especially if you haven’t been to Sydney before. The first half of the trip is through the inner and then outer suburbs, and you get a good sense of the sprawl of the city, as well as different architecture, and stuff like that. After about an hour, you begin the climb into the Blue Mountains, and get a bit more nature. The mountains themselves aren’t spectacular in the same way as the Rockies or the Sierra Nevada, but there are some lovely vistas and plenty of bush to see.
It’s about 3km (just under 2 miles) from the train station to the Three Sisters, and the main street has cafes and restaurants, as well as a bunch of quaint little antique and curio shops. We had lunch at the Paragon Cafe (the first few photos in the gallery). The food is pretty good, the service is no-nonsense and friendly, from waitresses who have probably been serving there for 20 or 30 years, and the interior has some lovely art deco finishes.
Once you’re down at the Three Sisters, you can basically spend as much or as little time as you want walking. If all you want is a view of the valley and the sisters, you don’t need to walk far at all once you’re there, but there are trails that go all the way down into the valley, and you could have yourself a pretty strenuous hike, if that took your fancy.
If you want an easier way down into the valley, you can take the scenic railway, at Scenic World. It’s about the same distance from the regular railway station as the Three Sisters, but in a slightly different direction. If you want a great view of the valley, the Scenic Skyway cable car is lots of fun, especially if it’s windy!
There are taxis in Katoomba, and for all i know you might even be able to catch an Uber, so if you don’t want to walk between all these attractions, you could probably get around the town by cab for not much money.
If you’d prefer the coast, and are willing to do a bit more walking, a really nice day trip is a walk in the Royal National Park, from Bundeena to Wattamolla and back. You catch the train from Sydney to Cronulla (about an hour), then catch a ferry across to Bundeena (about 30 minutes). The ferry ride makes for a nice change from the train.
The walk from Bundeena to Wattamolla is about 11km (just under 7 miles), but you have to turn around and come back again, so think about whether you can both cope with a 14-mile day. The walk isn’t too strenuous; there’s not too much elevation gained or lost. Wattamolla is very pleasant, but i don’t think there is anywhere to buy lunch there. It’s basically a lagoon and beach and picnic area, so you might have to pack your food with you.
The walk itself starts out through a sort of coastal scrub, and the first bit doesn’t provide much in the way of views, but once you hit the coast itself it’s really nice.
If you don’t want to walk so far, you don’t have to go all the way to Wattamolla. You can follow the same trail out to the coast, then to Wedding Cake rock, where you’ll get good views north and south, and then to the beach (i’m not sure if it even has a name) about another mile to the south, where you could stop to eat.
This walk is only about 3.5 miles each way. Last time i went, we saw whales about 500 feet off that beach, although their migratory patterns are seasonal, and we were there in winter.
If you do this, remember that you need to be back at the Bundeena wharf before the last ferry leaves, or you’ll be stranded.
