Each year on November 17, we celebrate National Hiking Day! It is a chance to unplug, hit the trail, and reconnect with nature. It’s not just good for your body and mind, it’s also an opportunity to engage with our region’s natural systems.

So we encourage you to lace up your boots, explore one of our local gems, and reflect on how your steps above ground help protect the water flowing below.

Where Your Footsteps Meet the Flow: How Hiking Protects the Aquifer

When you hike here in Central Texas, you’re often traveling across parts of the landscape that are critical to the health of the Edwards Aquifer, one of the region’s primary sources of groundwater. Many local preserves, such as Government Canyon State Natural Area, were developed specifically to protect the aquifer’s recharge zone: where rainfall and surface water seep through the ground, where Edwards Limestone is exposed at land surface, and makes its way down to replenish the aquifer. When we hike these trails, we get to experience the very places where this natural recharge process happens. The more we protect the land above, the better we safeguard the water below.

Here are two simple things to keep in mind as you hike:

Hiking does far more than strengthen your legs, it strengthens your connection to nature. Every step is an opportunity to reflect, restore, and recommit to protecting the land and water that sustain us.
✨ Why We Love Hiking:

● Connection: Feel the link between land, water, and community.

● Stewardship: Trails remind us that nature depends on our care.

● Mindfulness: The quiet of the trail offers space to slow down and recharge.

● Legacy: Protecting the aquifer ensures that clean water flows for generations.

2. Government Canyon State Natural Area: A hiker’s favorite, this area features more than 40 miles of rugged terrain, diverse wildlife, and stunning Hill Country views. It also plays a major role in safeguarding the aquifer. Click here to learn more about Government Canyon, park hours, and entrance fees.

3. Limestone Link Trail: Near the San Marcos area, this trail connects regional systems that cross the recharge zone. It’s a great spot for a moderate hike and a reminder of how natural landscapes support clean water. Learn about the Limestone Link Trail from this MySA article.

Before you head out, keep these tips in mind for a safe, enjoyable, and environmentally mindful hike:

● Bring at least one quart (32 oz) of water per hour of hiking.

● Apply sunscreen, wear a hat, and protect your eyes with UV-blocking sunglasses.

● Stick to marked trails to avoid damaging sensitive recharge areas.

● Pack out all trash, including food scraps or biodegradable items.

● Avoid disturbing wildlife or vegetation – every part of the ecosystem plays a role in protecting the aquifer.

● Wear sturdy shoes suitable for rocky terrain.

● Take a moment to pause and observe, the limestone formations, plant life, rivers, and streams that play a part in the Edwards Aquifer’s story.

On this National Hiking Day, take a trail not just to move your body, but to deepen your connection with the land you live on, and the water that flows beneath it. The Edwards Aquifer sustains communities, wildlife, and ecosystems across South-Central Texas. By hiking thoughtfully and practicing stewardship, you play an important part in keeping that water clean and abundant for generations to come. Happy Hiking!
