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: In past years, our Saturday and Sunday walks were identical. But not this year! This year we’ll have a new, adventurous Saturday schedule that will take us to 30 new destinations, each chosen for its botanical and/or geological significance. Most will be farther away, but it’ll be worth the drive to experience these iconic places and learn new things. Our provisional schedule is posted below, however there will likely be some last-minute changes as we try to make it all work out. (Be sure to get on our weekly email list to receive the most current information. Sign-up at stlnaturestudy@gmail.com)

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“.
