Yep, you heard right. Most of Central America is crawling with snakes. There are some very, very deadly species that inhabit all parts of this lovely department. There is a pit viper species called Castellana. This snake can be very aggressive and is capable of jumping to bite well above the knee also. Locals in the country side say that they generally do not even try to get help for someone that has been bitten by this snake because death comes so rapidly. There is the rattlesnake. It thought, no big deal, I have been around them all my life in the Pacific Northwest. Big difference...these are highly venomous and have a different color. Death is immenent. The Coral Snake, packs a load of death with its bite. This snake is not typically aggressive unless you touch it, or step on it. Get bit, say goodbye. There are no antivenom kits available in Nicaragua. Just pay close attention to where you step.
The biggest myth about Nicaragua is that it is a dangerous place with regard to personal security. This is simply NOT true. But there is a dangerous aspect to consider when traveling in the mountainous regions of Nicaragua. During the rainey months of May and October through December, rains can simply destroy roads without warning and or giving time for anyone to properly put up warning signs. Additionally, some of the roads out of Matagalpa can be pretty rough, just be prepared to take your time.
