The Library Blood-Red Pool, Thailand

From shark-infested swimming pools to one that kind of looks like the aftermath of a gruesome shark attack, this is another bizarre swimming pool design—this time one that is nestled in Thailand’s second largest island, Koh Samui. This is the one feature you need to stop by and take a dip in while you’re over here, if only for the gorgeous poolside views of the beach and the adjacent trendy modern library, The Lib. Swimming a few lengths in this blood-red pool may not look or sound too appealing, but you’ll be pleased to know that the off-putting deep crimson hue is a snazzy optical illusion.
