A super cheap day out, this one, if you're in the Quindio region of Colombia. You can hop on a bus to Salento from Armenia for 3,100 COP and stop in Boquia after about 30 minutes (the stop is right where there's a bridge over a river and a bunch of hostels/roadside restaurants). You'll know you're in the right place if one of the hostels has a big praying mantis sculpture outside it.
Aaaannnnddd that's the cost. 3,100 COP return, of course, but you don't need to spend any other money, unless you want a bite to eat (and then prices vary, but if you take at least 10,000 COP you'll definitely be able to get something filling). Oh wait, I just remembered there's a guy you've got to pay 2,000 COP to as you're technically on his property, but we got a free tinto (small black coffee) and decent conversation from him, so that's nice.
So, just over 8,000 COP for a decent day out (that's about $3 USD) - the trek isn't too difficult (though it was really muddy at certain points) and there's a little waterfall you can hike up to, as well as a nice 'hidden' river (that has crabs in it, so watch your toes).
[Prices correct as of November 2017]
