I like free so when I learned that I could visit the Manko Waterbird and Wetland Center for free, I went for it. The thing is that it required a bit of trekking, sidetracking and cautious crossing to get there. If you have a car, you can be there in a jiffy. If you’re going by the Yui Rail, it might take some time to get there, but it’s do-able, nonetheless.
