The cheapest option to reach the park is the milktruck or lechero 10,000 COP. It leaves Güicán at 5:30 am everyday, reaches El Cocuy around 6 am and then goes up towards the Sierra to collect milk before going back to Güicán. It can drop you at various location close to the cabanas.If you miss the milktruck or get to town late, you can hire a private car to drive you up there but this is a much more expensive option at least 80,000 COP.
