The largest lake in Parque Tres de Febrero is Lago de Regatas. The 1.2 mile circumference makes this a favored place for serious runners. Families and couples appreciate the absence of crowds. Birdwatchers clutch their binoculars while trying to identify over 30 species in the trees, on the islands and in the pristine water. Kayakers also have fun here. The lake is adjacent to the 18-hole municipal golf course Juan Bautista Segura.
