The City of McKinney maintains close to 3,000 acres of parks and open space and roughly 80 miles of hike-and-bike trail, which is a big enough system that most residents only ever really get to know two or three corners of it well. Here’s a rundown of the four that come up most often, and what actually distinguishes each one from the others.
Erwin Park: the mountain biking destination
Erwin Park is 212 acres, and it’s the one park on this list built primarily around a single activity: mountain biking. The park has roughly 10 miles of singletrack trail, along with a rustic campground for anyone who wants to make a weekend of it rather than a single afternoon ride. It’s noticeably different in character from the other parks on this list — less manicured, more wooded, and clearly built for trail riders rather than a casual evening walk. Anyone new to mountain biking and looking for a place to start in McKinney will find Erwin Park is where the local riding community actually rides, not just where a map says trails exist.
Towne Lake Recreation Area: the closest thing to a lake day in the city
Towne Lake Recreation Area centers on a 22-acre lake, with a 1.1-mile loop trail circling the water. It’s a genuinely different kind of outing than Erwin Park’s trail system — flatter, more social, and popular with families for an evening walk or a short fishing trip. The loop trail connects onward to the Wilson Creek paths, so it functions as much as a junction point in the city’s broader trail network as a standalone destination.
Bonnie Wenk Park: the biggest single park, and the dog park to know
At 216 acres, Bonnie Wenk is one of McKinney’s largest parks, and it does more with that size than almost anywhere else in the system. It has its own 5-acre fishing lake, separate from Towne Lake, along with miles of internal trail. The park’s dog park is the detail most residents actually bring up first: a two-acre, fully fenced, off-leash area, which is a genuinely large dedicated dog space compared to what a lot of similarly sized North Texas cities offer. Between the fishing lake, the trail mileage, and the dog park, Bonnie Wenk tends to function as the all-purpose park for households that want more than one activity available in a single visit.
Wilson Creek Trail: the connector that ties it together
Wilson Creek Trail is the piece that makes the rest of the system function as a system rather than a set of disconnected parks. The linear trail runs roughly 10 miles and links Towne Lake Park and Bonnie Wenk Park into a continuous greenway, meaning a rider or runner with enough stamina can genuinely travel between the two parks entirely on dedicated trail rather than cutting through city streets. It also serves a quieter purpose as a nature education corridor along the creek itself, away from the more recreation-focused amenities at either end.
Picking where to start
For a family with young kids who want water access without a serious hike, Towne Lake or Bonnie Wenk’s fishing lake are the easier starting points. For a mountain biker, Erwin Park is the obvious answer and not really a competition. For anyone who wants a longer run or ride and doesn’t mind covering real distance, Wilson Creek Trail is the piece of the system built specifically for that. And for a dog owner deciding where to spend a Saturday morning, Bonnie Wenk’s off-leash area is worth the drive even from the far side of the city.
None of these four requires a reservation or a fee to use, which is easy to take for granted in a city that’s grown as quickly as McKinney has over the past two decades — a lot of newer North Texas suburbs haven’t kept pace with park acreage the way McKinney’s system has, and the 80-mile trail count reflects a level of ongoing investment that shows up in daily use, not just in a city planning document.
Timing a visit around the season
Summer changes how each of these parks actually gets used. By mid-morning in July, the shadeless stretches of the Wilson Creek Trail and the open loop around Towne Lake’s 22-acre lake get uncomfortably hot fast, and the practical move most regulars make is starting well before 8 a.m. or waiting until the last couple of hours before sunset. Erwin Park’s wooded singletrack holds up better through the middle of a summer day simply because of tree cover, which is part of why it stays busy with riders even on the hottest weekends when the more open trails empty out. Bonnie Wenk’s dog park, with its two-acre fenced area, is worth checking pavement and ground temperature before a midday visit in August — asphalt and sun-baked open ground can get hot enough to burn a dog’s paws well before the air temperature alone would suggest a problem.
What each park lacks, worth knowing before you go
Erwin Park’s focus on mountain biking means it’s a less obvious pick for a family with a stroller or very young kids looking for a flat, easy walk — the terrain is genuinely rugged in sections. Towne Lake, by contrast, doesn’t have the trail mileage or wooded variety that a mountain biker or trail runner would want for a longer workout; its loop is short and better suited to an evening stroll than serious mileage. Knowing which park is built for which use ahead of time saves a wasted trip, especially for anyone driving across town rather than starting from a park already in their own neighborhood.
