Costa Rica-- Arenal Volcano and the Rio Arenal and the Rio Fortuna

 Let's start with the warm river, toasty after being heated by the Volcan Arenal. Beautiful, soothing, and free (one of the rare things we have done in CR that haven't cost a fortune)

 Another river we came across on our bikes was La Rio Fortuna. Not as toasty, but a lot of fun.
("Are there snakes in this river?".
"You don't wanna know.")
