iNaturalists' Hike in the Frontcountry

You can contribute to science this weekend and help San Antonio compete in the City Nature Challenge!

Take a citizen science hike in the Frontcountry with the Friends of Government Canyon. We’ll hike 4.74 miles over fairly level ground on Lytle’s Loop. Open to people 12 years and up; no pets please. Minors must be accompanied by their parent or legal guardian.

If you are interested in participating in the City Nature Challenge during our hike, please download the free iNaturalist app on your phone and set up an account before you arrive. We will photograph flora and fauna along the way, adding data to iNaturalist, a citizen science project that helps researchers monitor species and track changes in our world. Our efforts will be part of a worldwide effort to document urban biodiversity this weekend during the City Nature Challenge.

No reservation is required, but there is a capacity limit. This hike is open to the first 15 people who check in with the hike leader. Meet at the Frontcountry Trailhead, in Parking Lot C near the restrooms. Dress for hiking outdoors; sunscreen and hat recommended. Wear sturdy footwear appropriate for rough trails; bring two (2) liters of water PER PERSON, lunch, and a snack if you like. 

Plan to arrive early as mornings can be very busy. The Natural Area’s front gates open at 7 a.m.; plan to check in and be ready to go no later than 8:15 a.m. The hike starts promptly at 8:30 a.m. 

Though the activity is free, entrance fees to the Natural Area do apply. We often fill to capacity. To ensure entrance and save time at the Fee Booth, please pre-purchase and print out a day pass. Please note: reserving a Day Pass is not the same as making a program reservation! The hike is limited to the first 15 participants. If the hike fills and you miss out, you are welcome to take a separate hike on your own, and can still contribute your sightings to iNaturalist. 

If ADA assistance is required, please email accessibility@tpwd.texas.gov at least 2 weeks in advance.
