The Arbor Day Celebration is a fun-filled day where anyone can join us in a timed 5K or 10K run, a 25 Mile or 100K Bike Tour, or you can take part in an Educational Tree Workshop! All events commence at McAllen Municipal Park on Bicentennial. We invite everyone to come out and participate. There will be shirts, medals, free trees, and live music. It will be a Celebration that your whole family can enjoy.
