My family and I used GreenFrog Adventures in December 2016 for a 5 day tour to Arenal and Monteverde rainforest region. It was an expensive option and included a driver and personal guide and 2 nights accommodation. However, it the itinerary sounded very good so we decided to spend the extra money and have such luxuries. However, it was completely not worth the money and the trips that were included were very average and we could easily have arranged ourselves once there. Plus the personal guide (Giovanni) was very complacent and really explained very little to us, especially when we saw other guides there who were much more engaged and knowledgable it seemed than ours. Furthermore, there were a number of things that were set out in the itinerary that did not materialise - we had an inferior vehicle than the one promised to us, we were supposed to have private transportation all the time but this was not the case, things went wrong and we had no apology, some pf our tours were not private at all even though they were sold as such.
The bottom line is that this company will promise you one thing and charge you a fortune for it and then deliver something inferior and they think that is perfectly acceptable. They market themselves as one of the best tour companies in CR but this is very far from the reality we experienced. They are very expensive and you get very little for your money.
It is also not necessary to have private guides and pre book activities through agents for CR - it is easy to do so yourself and you will save yourself at least 50% by doing so. read more
