The Sam Houston Monument in Hermann Park is a pretty impressive sight. The area includes a reflecting pool, the bronze sculpture, and several gardens which may or may not include passing butterflies. When the sun is shining, it makes for a great photography spot.
The Earth Day celebration in Austin was held at the campus of Huston-Tillotson University on the East side of town. The campus is situated on a hill that has beautiful sight lines of Austin. There were butterflies, dinosaurs, bats, bands, performers, food trucks, drinks, and all sorts of fun to be had on a nice cool day in Austin.
The Texas Book Festival is the best time of the year to seek out migrating Monarchs. They typically look for a food source at the fountain on the State Capitol grounds. They are so much fun to photograph, because they don’t stay on one flower blossom for long, but flitter about on their own personal schedule.
