iNaturalist Hike

Let's hike North Onion Creek Trail

Let's get outside and explore north Onion Creek Trail! Using the iNaturalist app is optional. All age groups welcome. Total distance is approximately 1.5 miles. The trail does not have steep hills but is uneven in places. 

What is iNaturalist? iNaturalist is a citizen science app that allows users to upload photos of nature. Photos contribute data for scientists and naturalists. If you've never used the app or need some tips, we can help! 

What to bring: Please dress for weather and bring any hiking essentials needed. If you'd like to use iNaturalist, bring a smartphone with the app downloaded or a camera.

Meet: At the Horn Tunnel. Parking is available, but not restrooms. Restrooms are located at the boat ramp and the campground.

This program is free to attend with paid park entrance or a Texas State Park Pass.
