We had a wonderful two days at Volcan Arenal. The weather was clear and the volcano errupted just as we arrived. The lava display at night was fantastic. The flow right now is on the side facing the lodge so this is the BEST place to stay to see the volcano. The staff was friendly and very eager to please. The room was spacious and the view from the balcony can't be beat. We made our reservation through GreenStone Adventures and were so glad we went through an in-country travel agent. We lost our credit and debit cards on the remote Osa Peninsula and would have been stranded with no cash or credit had not Jamie from GreenStone met us in San Jose, taken us to the bank, and written a check against a credit card we had used when we made our reservation. Without a local agent we would have had nowhere to turn to for assistance. GreenStone took care of all our logistics and connections; everything went off without a hitch. We highly recomment GreenStone as your agent and the Arenal Observatory Lodge as the place to stay.
