I heard about this place through social media before the start of my trip. Arcadia is a hostel along the river with a water park : slides, zip line, swings. I had such a great time there, they have great outdoors activities that you can book from reception. You also have access to an outdoor gym. It’s a really chill out atmosphere, with gigs several times per week. I stayed in the riverside room for $20 but you can definitely find a bed in a dorm for $7.
