Welcome to Alamikangban & Prinzapolka
The main reason to go is the Río Prinzapolka river, which marks the southern boundary of natural pine forest that phases into tropical rainforest, with wetlands that are a haven for all sorts of birds. The fishing is also top-notch.
The towns themselves are traditional Miskito settlements: think board houses with rusted tinned roofs and no fences between neighbours.
Both towns, as well as the smaller communities lining the river, have indigenous government structures, so ask for the wihta (judge) or síndico (resource manager) when trying to find guides or lodging.
The entire region is susceptible to flooding; during rains, check on conditions before heading out.
