About this Event
There's a stretch of trail tucked along Blanco Road in where the terrain shifts, the air cools, and things get interesting. A unique microclimate runs through the Geology Trail, and it's home to more life than most people realize.
Come find out what's been hiding in plain sight.
On Saturday, April 25, from 8–10 AM, join Robert Doyal and Tracey Burke, Texas Master Naturalists and iNaturalist Ambassadors, for a morning nature walk where we'll use the free iNaturalist app to spot, photograph, and identify whatever we find — plants, insects, birds, and the stuff you walk right past every day without noticing.
No experience needed. If you can point a phone camera at a bug, you're qualified.
The Big Picture
This walk is part of the City Nature Challenge, a worldwide event where people in hundreds of cities spend four days discovering and documenting the wildlife around them. Everything you photograph becomes part of a global biodiversity dataset — and helps scientists better understand what lives right here across our 12-county San Antonio Metro Area. That beetle clinging to a piece of bark? That's data. The lichen creeping across the exposed rock? That's a contribution. You're not just going for a walk — you're mapping what lives here.
