Despite being located within Austin City limits, just 13 miles from downtown, McKinney Falls State Park feels like a world away from the city. The 641-acre park has 80 campsites and is home to Onion Creek, where park-goers can swim and fish or explore the hiking and biking trails and various points of interest, like a prehistoric rock shelter, the remnants of an old Texan homestead, and one of the oldest cypress trees in the state. The park’s serene natural beauty, a plethora of activities, and proximity to Austin make it a favorite among outdoor lovers in the state capital.

Things to Do

There’s plenty to keep visitors busy for hours, including hiking, fishing, mountain biking, swimming, bouldering, and picnicking. Onion Creek is a fabulous place to swim and cool off from the white-hot Texas heat. It’s super fun (and refreshing) to walk along the limestone ledges, relax near the falls, and submerge your body in one of the many pools of water. A fishing license isn’t required to fish here and the park has ample shoreline access to Onion Creek.

The park is home to one of the oldest bald cypress trees on public land in Texas, affectionately dubbed “Old Baldy.” The 100-foot tall cypress is estimated to be well over 500 years old. There are several other points of interest, like the historic rock shelter that’s listed on the National Register of Historic Places and the former homestead of Thomas McKinney (who was a racehorse breeder and one of Stephen F. Austin’s original colonists). Interestingly, the park is also part of the 300-year-old El Camino Real de Los Tejas, which is a trail that was once traversed by French, American, and Spanish pioneers.

Best Hikes & Trails

There are several trails in McKinney Falls State Park, which are all relatively short and easy. However, if you're in the mood for a long hike the trail system connects all the trails in a loop, so you could technically hike all of them.

  • The Onion Creek Hike & Bike Trail: This is an easy pretty paved 2.8-mile loop trail that goes past the Onion Creek waterfall and swimming hole. It's your best bet for an easy bike ride.
  • Homestead Trail: This 3.1-mile trail is moderately challenging, and you do have to cross the creek, but is also open for bikes. This trail bypasses several of the park’s historic sites, like the McKinney Homestead, the Gristmill, and the Smith Family Picnic Table. 
  • Rock Shelter Trail: This .6 mile trail is easy and flat, known for having many wildflowers when the season is right, and it is also good for trail runners.
  • Picnic Trail: This half-mile trail starts at the Horse Trainer's Cabin and finishes at the connection of the .1-mile Gristmill Spur Trail which will connect you to the Homestead Trail or the Homestead Trail shortcut
  • Flint Rock Loop Trail: A 1.5-mile loop trail, from which you can connect to the Homestead or Williamson Creek Trail
  • Williamson Creek Overlook Trail: This 1.1-mile moderate trail is a mostly flat trail that tends to be less busy.

Where to Camp

There is just one main campground at the park with 81 campsites. The campgrounds are divided into different camping areas with multiple restrooms (Grapevine Loop, Little Oak, Moss Loop, Big Cedar, and Youth Group), but are all generally within the same spot circumscribed by the Onion Creek Hike and Bike Trail. Every campsite has a tent pad, water, restrooms, and a fire ring with a grill. There are also six cabins on-site which can sleep up to four people comfortably. Cabin amenities include air-conditioning, a patio, microwave, mini-fridge, and a fire ring with a grill. Cabins do not have bathrooms, but the restroom and shower house is a short walk away. You’ll also need to bring your own linens, and pets aren’t allowed. You should reserve your campsite in advance online before you decide to stay overnight.
