Hike
Cape to Cape
The 135km trail between Cape Naturaliste and Cape Leeuwin in the Leeuwin-Naturaliste National Park meanders around precipitous coastal scenery, forests and along beaches. Periodic established campsites a offer a spot to pitch your tent, toilet and watertank. The northern trailhead is 15km south of Dunsborough and ends 6km shy of Augusta, passing through four towns along the way.
Munda Biddi Trail
If you prefer two wheels the 498km Munda Biddi Trail goes from Mundaring in the Perth hills to Nannup in the South West. The trail varies in terrain but is not extraordinarily challenging, making it a pleasant ride for all ability levels. Campsites with shelters are spaced a days ride apart and towns along the way give you chance to return to civilisation.
Bibbulmun Track
A hike on the nearly 1000km trail from Perth to Albany, passing through many south west towns is arguably one of the best walks in WA. The signposted trail wanders through forest, wetland, coastal, and grassland environments to campsites equipped with a three-sided timber shelter, rainwater tank and toilets. Pocket sized map books can be bought from the Bibbulmun track Foundation. If taking on the entire length is too daunting, several sections make good 2-5 day jaunts.
Railway Reserve Heritage Trail
An easy, but interesting, trail in the Perth Hills that follows a 40km loop along the route of the former Eastern Railway abandoned in the late 50's. The most popular stretch is in John Forrest National Park from Swan View to Hovea passing through the spooky Swan View tunnel, over a decaying wood framed bridge to the magnificent Hovea Falls. The areas relatively unspoilt bushland is a major wildlife corridor so it's not uncommon to see groups of kangaroos at dusk among other native animals.
Swim
Lake Argyle in Kununurra
As one of the largest man made lakes in Australia Lake Argyle is a good place for a dip with the friendly crocodiles. Kununurra also has a number of secluded waterholes around that make a refreshing place to float about with a beer during the humid wet season.
Serpentine Falls in Serpentine
Located a 35 minute drive east of Mandurah, is an excellent place for a swim.
Cable Beach in Broome
One of Western Australia's most well known beaches, with warm water and sand swept clean by the tides every day. You can't swim there from October until May because of Box Jellyfish as with any beach north of Exmouth. Irukandji are also a risk at other times of year, and the beach can also be closed if a crocodile cruises past.
Dive
Rottnest Island
Not far off Perths coast its has many underwater caves that are worth exploring.
Ningaloo Reef near Coral Bay
probably the place to dive with abundant coral, marine life and a good chance of seeing a whale shark.
