Yes, you pay a small entrance fee and will find an extraordinary collection. The only small "problem" is that the orchids generally are not supplied with ID, but it shouldn't stop you visiting the place. I think that the Archila place has far more rare species than I have seen elsewhere. Before you go, take a look at: Orchids - Orqudeas
Thanks. Will definitely put that on the list for our next road trip to Coban.
