Hi Jaya, the night walk took place at Monteverde. Originally it was meant to leave from the hotel grounds but for some reason this was changed and we took a minibus to a place where we got kitted out with jackets and torches. We had a guide who brought us into the jungle and to be honest we saw very little! As with all these nature/jungle walks it is the luck of the draw. As far as I remember, we saw some nesting birds, a couple of spiders and other insects and a colony of leafcutter ants. We didn't see any snakes, but that's not to say that you won't either! The ground was rough underfoot but we all went very slowly (it was pitch dark apart from the torchlight) so this wasn't a problem. I hope JY have changed the hotel there as it was dire (the only bad one we stayed in).
Any other questions, feel free to ask!
All the best,
Bob
