The world’s most trusted and respected source of travel has named Tasmania as one of the world’s top ten regions to visit in 2015. Tasmania ferry is the fantastic location and is the only Blackwood sinkhole on Earth, making it an once-in-a-lifetime kind of attraction. Visit and you'll get a glimpse into a world like no other. Caves, springs, streams and dense forest are just some of the sights you will come across on your adventure here.
Tasmania is so compact that you can be easily overwhelmed by its natural beauty all in a day! The visitor centre can be found on the edge of the sinkhole rim, which is located in Tasmania's West. Its location is Head to 26059 Bass Highway, Togari, approximately two hours' drive from Devonport, or a 45 minute drive from Stanley. Once you arrive in Tasmania ferry things start to get pretty exciting.
The Blackwood trees are a type of wattle and are fascinating in them. They rarely flourish anywhere in the way they do at Dismal Swamp, so it's a great place to see them. Some of them are even up to 50 meters tall. Their timber is also particularly valuable, a favourite of craft-makers, carpenters and other woodworkers. While you will see the trees intact in the forest, you can also see the high-quality design effect they produce in the visitor centre, with its impressive curved Blackwood wall.
