Th park contains the highest mountain of the ABC-Islands and the whole Caribbean Netherlands. You should have a car to drive around all of its places. Hiking up to the top of Christoffel mountain is not too hard but, anyway, stay alerted and be carefull especially during a rainy day, while the rocks on your road are slippery. If you would like to see how the surronding areas, the roads, the top of this mountain and the views from this mountain look like, check the link below:
