Looks like all commenters easily spotted the snake in this photo.
It’s about a third of the way from the top right. Here’s a closer shot from roughly the same angle.
As Andrea J determined, this is an eyelash viper, Bothriechis schlegelii. It’s difficult to pick up an ecotourism brochure in Costa Rica and not see a picture of the yellow variety of this species.
Look out for a separate post on this individual with many more photos.
Oh, and don’t worry, I kept a respectful distance. This encounter reminded me why I always carry around a teleconverter.
