While there are buses from Bogotá to the nearby town, during this time of Covid we recommend you taking a car from the airport to ArteSumapaz. We can arrange the driver to meet you at the airport. The cost is about $75-80 US. We can pay the driver and you can reimburse us via Paypal if needed.
Also, we've been successful hailing an UBER from Bogotá. If you do so, you'll want to take an Uber Comfort, as smaller cars can have a tough time on some of the roads.
