In its early years, Alvarado Park was served by its own streetcar line from the East Shore and Suburban Railway, a Key System precursor, which was later discontinued. The park district made certain improvements including a new children's play area, conversion of parking into meadows, and demolition of dilapidated structures. It was also the home of the Grande Vista Sanitarium, later known as Belgum Sanitarium. Though the associated buildings have since burned to the ground, their foundations and the surrounding grounds, including an orchard remain. The park also features distinctive and noted stone masonry, retaining walls, and classical stone lampposts. The lampposts are no longer lit. A stonework bridge spans Wildcat Creek in the park main entrance. The park district is currently struggling to return the river to a more natural state in hopes of restoring its fish population and their runs. The park also featured an open air pavilion dance hall which was converted to a roller rink, and subsequently destroyed by fire.
