Outside of the station building is a one-acre native plant butterfly garden. The garden is in full bloom in April and May, and the butterflies follow soon after. Other pollinators like bees and hummingbirds are also attracted to the colorful flowers here.

Rangers also offer a variety of educational programs and self-guided hikes. These programs provide opportunities to learn about the importance of this sanctuary and the need to preserve the wildlife. The outdoor classroom can cater to students of all ages, local scouts programs and other youth-oriented organizations.
