Nature lovers might want to consider making the trip to the isolated towns of Alamikangban, about 70km southeast of Rosita, and Prinzapolka, another two hours by boat along the Río Prinzapolka river to the Caribbean coast. The main reason to go is the Río Prinzapolka, 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: typically comprising board houses with rusted tin roofs and no fences between neighbors. 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.
