Glendora is home to what is probably the largest Moreton Bay Fig south of Santa Barbara. The "Big Tree" was planted in the late 1880's by Mr. Edgar J. Owens, one of Glendora's early residents. The tree's botanical name 'Ficus Mactophylla' is commonly called Moreton Bay Fig and is named after the Moreton Bay Region of Australia where the species grows naturally. The tree is known for its large buttress roots, helping it reach approximately 99 feet tall and 47 feet in diameter. The tree is also supported through a system of steel cables strung throughout the canopy, which work to support the large heavy limbs overhanging the park and surrounding streets. After the house that it shaded was torn down in the mid-1960's, the city took possession of the tree and in the 70's, converted the small block of land surrounding the tree into "Big Tree Park". Glendora residents affectionately refer to the tree as the "Big Tree". In October 2010, the city expanded the park and built a large wood gazebo. In 2016 the city expanded the park again to 15,000 square feet, replaced fencing, and updated the landscaping to be drought tolerant.

Big Tree Park is available to rent for family reunions, weddings, and corporate training/events. All reservations are for a maximum of 2 hours and include 50 chairs and 1 six-foot table. There are no restrooms available at this park. Whether you’re aiming for a laid-back event, or a fun filled day of games, trainings, or celebration, Big Tree Park offers the perfect atmosphere to relax and escape the everyday hustle and bustle.
