I'll be writing more later about each place we visited: Managua, the Rio San Juan, the Solentiname Archipelago, the Selva Negra coffee plantation, the colonial city of Granada, Ometepe Island, and San Juan del Sur.
In the meantime, here are some photos. From the top:
-- Concepcion Volcano on Ometepe Island (seen from the air on a fight over Lake Nicaragua).
-- The small La Costena airplane that took us from Managua over Lake Nicaragua to San Carlos, where Lake Nicaragua drains into the Rio San Juan.
-- The balcony of our treehouse cabin at Sabalos Lodge on the Rio San Juan, a neat eco-lodge with a focus on helping the local community, which is very poor.
