Lake Crabtree County Park: Mountain Biking and Sailing Right Next to the Airport
Singletrack, sailboats, and a lakeside greenway — all under the RDU flight path. Here’s the full playbook.
There’s a 215-acre lake wedged between I-40, Aviation Parkway, and the south end of RDU’s runways, and most people who live in the Triangle have driven past it a thousand times without stopping. They’re missing the most underrated outdoor afternoon in Wake County. Lake Crabtree County Park is the rare spot where you can rent a sailboat, ride real mountain bike singletrack, and walk a flat lakeside greenway — all in the same visit, all while watching jets bank low overhead on their final approach. It’s loud sometimes. It’s also kind of glorious.
This is the park people sleep on because they assume “next to the airport” means “afterthought.” It doesn’t. Here’s how to actually use the place.
The basics: Lake Crabtree County Park, 1400 Aviation Pkwy, Morrisville, NC 27560. It’s a Wake County park, so admission is free and parking is free. The park gates open at 8 a.m. and closing time shifts with the season — roughly 7 p.m. in winter, as late as sunset/8 p.m. in peak summer. Don’t get locked in; they close the vehicle gates on time.
The Mountain Bike Trails — Morrisville
Trailheads off the main park road and the Old Reedy Creek side
This is the reason a lot of people come, and it’s the part newcomers don’t expect. Lake Crabtree has a genuine network of mountain bike singletrack — tight, twisty, root-laced dirt that connects into the broader Black Creek / Crabtree trail system and, for the ambitious, links toward Umstead State Park’s bridle trails across the creek. The riding here is classified mostly beginner-to-intermediate: flowy, punchy, and forgiving, with enough roots and short technical bits to keep it honest. It’s where a ton of Triangle riders learned to ride dirt.
The trails are directional and signed, and — this matters — they close when wet. Riding muddy singletrack tears it up and gets trails shut down. Check the TORC (Triangle Off-Road Cyclists) trail status line or their site before you load the bike. If it rained yesterday, assume closed and check anyway.
What to bring: actual mountain bike, not a beach cruiser. Helmet. Bug spray in summer — the lowland sections near the water hold mosquitoes. Go early on a weekend morning to beat both the heat and the foot traffic.
Boat Rentals — The Lakeside Concession

Here’s the move most people never make: you can rent a boat and get on the water without owning a thing. The park concession rents kayaks, canoes, pedal boats, and — the sleeper hit — small sailboats by the hour. On a breezy afternoon, watching little sailboats tack across the lake with a 737 climbing out behind them is the most quintessentially Lake Crabtree image there is.
Rentals are seasonal — generally open spring through fall, weather and wind dependent, and typically weekends-heavy in the shoulder months. Bring cash or a card, expect to sign a waiver, and know that sailboat rental may require demonstrating basic competence or sticking to calm conditions. If you’ve never sailed, a kayak or pedal boat is the low-stakes way to spend an hour on the water. No private gas motors — this is a quiet, no-wake lake, which is exactly what makes it pleasant.
Want to bring your own kayak or canoe? You can. There’s a launch, and a launch fee may apply for private boats. Go in the morning when the water’s glassy and the wind hasn’t picked up.
The Black Creek Greenway — Morrisville to Cary
Greenway access from the park’s lakeside trail
If bikes and boats sound like too much commitment, the greenway is the easy win. The paved Black Creek Greenway runs along the lake and threads south through Morrisville into Cary, connecting to the larger Cary greenway network and, on the north end, toward Umstead. It’s flat, stroller-friendly, dog-friendly (leashed), and shaded in long stretches.
The lakeside segment is the prettiest part — open water on one side, woods on the other, and the constant low theater of planes overhead. It’s a legitimately good run or casual ride, and because it links into Cary’s system, you can make it as long as you want. Round-trip from the park down to the Cary greenway hubs and back is a solid few miles. Mile markers and trail maps are posted at junctions.
This is also the most accessible piece of the park — paved, gentle grade, good for kids on training wheels and grandparents alike.
What Else Is Here
The park isn’t just the three headliners. There’s a fishing dock and bank fishing for largemouth bass, crappie, and bream — bring a NC fishing license and your own gear. There are picnic shelters (some reservable through Wake County, the rest first-come), open fields, a volleyball area, and a playground. It’s a genuinely good cookout spot if you reserve a shelter ahead.
One honest note on swimming: there’s no swimming in Lake Crabtree. It’s a boating, fishing, and paddling lake, not a beach. Don’t show up in a swimsuit expecting to wade in.
The Airport Thing — Feature, Not Bug
Let’s address the planes directly, because it’s the first thing anyone notices and the thing that makes people skeptical. Yes, RDU is right there. Depending on which direction the airport is running its runways that day, you’ll have aircraft passing low overhead — close enough to read the airline, close enough that conversation pauses for a few seconds. Aviation Parkway isn’t named ironically.
For some people this is a dealbreaker. For most, it becomes the park’s signature. Plane-spotters genuinely come here on purpose — the south side of the lake and the open fields give clean sightlines to the approach. If you’ve got a kid who loves airplanes, this is a free afternoon that’ll blow their mind. Bring a blanket, pick a field, watch the bellies of jets float over the water. Few free experiences in the Triangle hit like that.
How to Do Lake Crabtree Right
A few rules from people who use this place:
- Go in the morning. Cooler, calmer water, emptier trails, better light, and you’ll beat the summer afternoon thunderstorms that roll across the Triangle.
- Check trail status before mountain biking. Wet trails are closed trails. Riding them anyway ruins it for everyone and gets the network shut down.
- Call ahead on boat rentals. Hours are seasonal and wind-dependent. Don’t drive out assuming sailboats are waiting.
- Bring bug spray and water April through October. The lowland sections are mosquito country.
- Mind the closing gate. They lock the vehicle gates at posted closing time. Set a phone alarm.
- Combine it. Paddle for an hour, then walk the greenway, then grab food in nearby Morrisville or Cary. The park is fifteen minutes from everything in the RTP corridor.
Lake Crabtree is proof that “next to the airport” can mean “wildly convenient” instead of “skip it.” It’s free, it’s varied, and it’s hiding in plain sight off Aviation Parkway. Stop driving past it.
