Weekend Botany Walks
2026 Schedule
Saturdays and Sundays at 10:00
Come walk with us on these free weekend Botany Walks in our beautiful St. Louis.
Help us make sense of our natural world as we walk in the great open classroom.
New Saturday Schedule: This year our Saturday walks will be different from our traditional Sunday walks. Our new Saturday schedule will take us to some destinations that are special not just for their botany but also for their geology. Many are farther away. (Please be aware that the Saturday schedule is not yet final. Expect lots of last-minute changes as we try to make it all work out. )

There are some things in life that you just can’t learn well from books. Field Botany is one of them. You have to “walk the walk” as they say. So you might as well walk with us. You’ll find that botanizing with a group is usually more productive than botanizing alone. More eyeballs. Plus you get to meet others who share the same enthusiasms, which is no small feat.
Please join our email list because sometimes we have to change our schedule at the last minute (due to trail closures, flooding, heavy tick or mosquito outbreaks, etc.). A couple of days before each walk you’ll receive an email with the latest trail information, our “Family-of-the-Week”, our “Topic-of-the-Week” and a checklist of the plants we’ll be looking for. To sign up, just send a request to: “STLnaturestudy@gmail.com“.
Want even more? The Webster Groves Nature Study Society is well known for their excellent nature programs, including their popular Monday Morning Botany Walks led by teacher and botanist John Oliver.
