2) Arenal Area: we stayed at El Silencio del Campo and it was very nice and quiet. Preferred their hot springs to the big expensive ones next door at Eco Termales! Breakfast was decent and the Reception people were all very friendly and i appreciated they did not push on us any trips, they were very laid back. I hesitated to go there due to the big ugly hotel next door, but we managed to ignore it. What an eye sore! How was it allowed to have something like this built in that location?! Hotel close enough to town to get there if needed for dinner.
3) Discovered that there is a bus from La Fortuna to Tilaran which stops everywhere on the road. We hailed it down every morning as it passed by El Silencio del Campo Hotel and went to Lake Arenal one day from where we walked the 2km up to Hanging Bridges. The next morning we took the bus to El Silencio Reserve and it stopped right in front of it. The 3rd morning we went to Arenal National Park and the stop was about 3km to the entrance, but if you like to walk and have time, why not? The bus only cost $2. Compared to taxis cost between $20-25. Only problem: there is only 1 bus a day going West and coming back in the afternoon. We somehow spent to all the places we went just the time when we caught the bus back! (around 2:30pm leaves Lake Arenal). This bus is not mentioned in any of the guide books i had!
Hanging Bridges was my favorite most awesome place. I have seen a lot of tropical vegetation in my life, but never structures like those. Not to be missed.
