The walk across the suspension bridges is an experience. It rocks and shakes, but it holds! Only two people at a time, and keep your distance!

A very well-signposted tour. It's best to wear sturdy shoes, as it's easy to twist your ankle. If the weather's nice, don't forget your swimsuit and barbecue gear, as there are many beautiful spots where you can grill.

A small bridge connecting the islands. A bit wobbly, but still easily accessible even for those with a fear of heights.
