Brisas del Nara is a small tour company located in the foothills of the Cerro Nara mountain range in Costa Rica. They offer a horse back riding tour through the jungle to various waterfalls and a beautiful river, and they are now adding a new tour which is similar but done in a safari truck instead of on horses.
I had the pleasure of trying out the tour and taking pictures for their website. It was truly an amazing experience. Butterflies would flutter up to the truck and fly along with us for portions of the ride. And since you are driving in the open air you can hear all of the jungle noises around you. The color of the river is just amazing. It is so inviting. And if the safari truck isn't exhilarating enough for you, just try the 416 foot hanging bridge that is suspended 131 feet above the ground.
