Will be spending 8 days at Banana Azul Hotel near Puerto Viejo in January 2014. Will be renting a bike to see the area and will be visiting the Jaguar Rescue Centre. Is it worth about $60 per person to hire a guide and take the Gandoca Manzanillo Hike. What if anything will I see or experience on this Hike that I won't experience if I don't take the hike? Also, how long a hike is it?
