Palacio Nacional
The old national palace is now a museum featuring several salons with exhibits highlighting the indigenous Nahuatl people and the 2,500 year old stone sculptures they left behind. A smattering of popular arts and cultural exhibits round out the museum, which also features a beautiful courtyard garden.
Catedral de Managua
Ruins of the city's old cathedral are a remembrance of the damage caused by a 1972 earthquake that destroyed much of central Managua.
Tiscapa Lagoon
Fresh water lagoon in the crater of an extinct volcano. This is where you'll also find the landmark silhouette of Augusto Sandino as well as military memorials. Zip-lines over the lagoon let you fly across the water in a harness for a fee.
Huellas de Acahualinca
Footprints of a group of around 10 people that walked towards the lake 6000 years ago. The tracks were found 4 meters below the surface and were preserved thanks to a nearby volcano eruption. Note that the site of the footprints is in a very bad neighborhood. You must take a taxi to get there and take a taxi to leave. Do not attempt to walk there.
Rotonda Ruben Dario
There is a lovely fountain at the Ruben DarÃo Rotonda that is lit up at night and visible from Tiscapa.
