If you’re looking for extreme, you should definitely check out some of the locations on
Tour2sky zip lines. I did one in Hawaii, and it was insane! It felt like flying, especially when you’re zooming over valleys and waterfalls. The speed and height were way more intense than anything else I’ve tried. I was honestly nervous at first, but once you’re up there, the adrenaline takes over, and it’s a total rush. Highly recommend it if you’re craving a big thrill!
