Agree with other reviews but would add that we were both highly impressed that Samuel really gives back to his community.  He grows and promoted native plants to be planted by local farmers in their tree rows to help all sorts of native butterflies, birds and animals.  Good for farmers to have the extra pollinators then too.  Real win-win.  Not sure how much of his tips he puts back into helping improve the local private farms but think it considerable.  We were happy to feel like our generous tips added so much and encourage everyone to tip the generous guides....generously !

Samuel was our guide for a hike through Monteverde Biological Reserve and was one of the best we've had. Samuel was very knowledgeable and was able to answer all of questions. He was patient and truly wanted us to have the best experience. We could tell Samuel loves nature. His passion and love for all things in the forest was completely apparent. We highly recommend Samuel!

Samuel Arguedas proved to be an excellent guide with amazing expertise and knowledge and great English language skills. We can highly recommend him as someone to seek out if you're visiting the Monteverde region. Thanks to him, we have some of the best photos of wildlife in our 10 day trip to Costa Rica
