The tunnel is a relic of the old rail route through Picton, before realignment to reduce gradients. It was then used to grow mushrooms and is said to be haunted. It is a short walk to the other side.
A rail museum dedicated to preserving heritage rolling stock (and claims to hold Australia's largest collection of heritage rolling stock). You can also take a ride on the heritage steam train along the Picton–Mittagong loop line, which is a mostly disused railway line.
A as part of the Greater Blue Mountains Area next to the former Couridjah station. The lakes gave it the world-heritage status.
Sydney Skydivers operates exclusively from the nearby airport at Wilton (the turn off is a few hundred metres from the Picton exit off the Hume Highway (freeway)). Full licence training also available. There is a cafe with a decent coffee machine and toasted sandwiches at a reasonable price if you just want to watch. Or if your idea of lunch is a pack of corn chips with a tin of bean mix and cheese for around $8, they can help you with that too. Picnic tables if you'd rather bring your own. Entry is free, $275 for a tandem skydive. Discounts available for a second jump on the same day. Pick a time online, but usually it is okay to just drop in.
