If you're visiting Nicaragua, you shouldn't miss Matagalpa - a beautiful, mountainous, cool area where you can hike around the Selva Negra nature reserve and take coffee or cocoa tours. The Selva Negra also has an on-site restaurant with an outdoor deck overlooking a small lake, perfect for bird-watching. You can sit outside during your meal and enjoy the view, or take a walk around the lake to the special "birdwatching patch" to commune with some local geese.
On the road between Matagalpa and Jinotega is a magical place called Selva Negra. It's a resort and reserve, where you can hike, take a coffee tour, spend the night, and eat delicious hamburgers. I highly recommend the Atajo trail to the Peter and Helen trail. It's steep, but takes you up to the top which is cool and breezy. The loop takes about 2 hours.
