Los Chiles is a border town city in the north of Costa Rica.
It's pretty wealthy because of its geographic border situation. It's the most northern town and one of the two official border crossings between Plains of the North, Costa Rica and Rio San Juan Region in Nicaragua.
Pretty small - walkable! An ATM is available on the main street.
On the Riverbank of the Rio Frio you can see sometimes Howler Monkeys and different birds. There´s a great path that goes along the bank, heading north from the dock. You´ll see lots of locals fishing, which is a great way to spend a day.
If it´s a weekend, you can probably catch an afternoon mejenga (soccer match) in the Central Plaza.
You can hop on a Tour boat driving around on the Rio Frio watching birds and stuff like that. Most of these tours are actually organised from Fortuna.
There are plenty of restaurants and sodas all over town.
Once dropped off by the bus, the main (and only) road leads to the harbour (a 10-minute-walk).
1. Get your passport exit stamp at the migration building
2. Straight across the migration building there is an improvised counter. Pay your boat ticket (7 000 Colones, US-$ 14) and double-check if you were put on the list
3. At the port pay your port tax (600 Colones) (7000 Colones = 14 US-$, before leaving you have to pay an additional port tax - 600 Colones)
