Ready to find out where it is? Keep reading because this hidden gem is the stuff summer dreams are made of.
Where Is It?
Dale Hollow Lake is located on the Tennessee-Kentucky border, with the Tennessee side lying within the Upper Cumberland region.
If you’re coming from Nashville, you’re looking at a 2-hour drive northeast.
From Knoxville, it’s a little over 2 hours northwest.
The closest town with supplies and gas stations is Celina, which is just a quick 20-minute drive from the lake’s main marina.
It’s totally doable for a weekend getaway or even a spontaneous day trip if you’re nearby!
About
Dale Hollow Lake is the kind of place that makes you do a double take.
Yes, the water really is that clear.
This massive lake straddles the Tennessee-Kentucky border and stretches across 27,700 acres of sparkling water.
It’s fed by the Obey River, and thanks to super low pollution and strict shoreline protections, it’s known for having some of the cleanest water in the eastern U.S.
You can literally see your toes while treading water!
The Tennessee side of the lake is quieter and more laid-back, with scenic coves, forested hills, and peaceful stretches of shoreline perfect for swimming, boating, or just floating in the sunshine.
Dale Hollow is also where record-breaking smallmouth bass are caught (it’s home to the world record actually!) so fishing here is a big deal.
And fun fact: the lake was created in the 1940s by the U.S. Army Corps of Engineers when they dammed the Obey River.
They even had to relocate the town of Willow Grove, which is now completely underwater.
On a clear day, scuba divers can still spot remnants of the old town below the surface, including building foundations and the schoolhouse site.
The whole area has a relaxed, back-to-nature feel, with cozy campgrounds, family-owned marinas, and old-school general stores nearby.
If you’re looking for a spot to unplug, unwind, and float around in ridiculously clear water, this lake is calling your name.
Things To Do
Alright, so now that you know Dale Hollow Lake is basically the poster child for crystal-clear water, let’s talk about all the fun stuff you can actually do while you’re there.
First up: swimming.
The water is clean, calm, and perfect for a long, lazy float.
There are no lifeguards, but you’ll find plenty of little coves and shoreline spots where you can wade in, toss in a floatie, and soak up the sun.
One popular swimming spot is Willow Grove Recreation Area, which has easy lake access, picnic tables, and shaded areas to cool off when the sun’s blazing.
If you’re more of a boat-all-day kind of person, Dale Hollow is boat heaven.
You can rent pontoons, jet skis, fishing boats, and even full-on houseboats from places like Dale Hollow Marina, Willow Grove Resort & Marina, and East Port Marina.
Houseboating is actually a big thing here—you can spend the night on the water, complete with a rooftop deck, grill, and all the floaty toys your heart desires.
Kayaking and paddleboarding are also solid choices, especially in the quieter coves where the water’s still and the scenery is all rolling hills and wooded shoreline.
And for hiking fans, there are several scenic trails around Dale Hollow Lake, like the Accordion Bluff Trail, a 7.5-mile route with sweeping views of the lake and forest near the dam area.
If you want something shorter, explore the Pleasant Grove Recreation Area, a peaceful day-use spot with picnic sites, lake access, and great birdwatching opportunities.
Birdwatching is also a big thing here so keep your eyes peeled for bald eagles, herons, and wild turkeys while you’re out exploring.
There’s also a campground near the dam—Dale Hollow Dam Campground—with tent and RV sites near the water, plus clean restrooms and easy access to the lake.
And don’t skip the Obey River Picnic Area, especially if you’re visiting with family.
It’s got a swimming beach, a playground, and even a basketball court.
Got your fishing pole? You’ll definitely want to bring it.
This lake is famous for smallmouth bass, and serious anglers come here hoping to break the current world record (11 pounds, 15 ounces, caught right here in 1955).
You’ll also find largemouth bass, crappie, bluegill, and catfish so whether you’re a seasoned pro or just want to toss a line off the dock, there’s something biting.
If you’re into scuba diving (or want to try it), a few dive shops near Willow Grove Marina offer gear rentals and information on popular underwater sites including the ruins of old Willow Grove.
It’s a super unique experience with submerged buildings, stone walls, and even traces of old roads from the town that used to stand here.
Know Before You Go
Alright, so if you’re already mentally packing your bags (same), here’s everything you need to know before you roll up to Dale Hollow Lake:
Best time to visit?
Late spring through early fall is prime time.
From May to September, the water is warm enough for swimming, the marinas are fully open, and everything is green and gorgeous.
July is the busiest month, especially around holidays, so if you want fewer crowds, aim for early June or mid-September.
Getting there:
Your GPS will get you there just fine, but cell service can get a little sketchy the closer you get to the lake, especially in the hills.
Plan to download maps ahead of time and maybe screenshot your directions, just in case.
If you’re coming from Nashville, hop on I-40 east, then cut north through Cookeville and Livingston.
From Knoxville, you’ll go west on I-40 and then work your way up through Monterey and Celina.
Either way, expect some windy back roads toward the end but hey, the scenery makes it worth it.
Fees & access:
Most public areas around the lake are managed by the U.S. Army Corps of Engineers and offer swimming, hiking, and picnicking.
Some boat ramps or day-use areas, like Obey River Park, may charge a small day-use fee (around $5).
If you’re renting a boat, prices vary big-time depending on what you’re getting—pontoons start around $250/day, while houseboats can go from $1,695 for 3-4 nights.
Camping options:
There are several campgrounds around the lake, but one of the most popular is Dale Hollow Dam Campground.
It’s run by the Corps of Engineers and has tent sites, RV hookups, clean bathrooms, showers, and direct lake access.
Sites usually run around $32–$75 per night, and it’s best to book in advance during summer.
Obey River Campground is another solid option as it’s located along the lake near a large swimming beach area and is great for families.
If you’re more into cabin life, check out Willow Grove Resort & Marina, which offers cozy cabins with lake views and full kitchens.
Nearby things to check out:
Standing Stone State Park is just 20 minutes away with more hiking trails and a scenic lake of its own.
The town of Celina has a few local spots to eat (try Ricky Bobby’s Roadhouse for some chicken tenders).
Cordell Hull Birthplace State Historic Park is about 45 minutes from the lake and great if you’re into history and short nature trails.
Other tips:
Bring water shoes as some of the shoreline areas are rocky.
Gas up before you get close to the lake since stations can be few and far between.
And definitely pack some food or even a cooler.
You won’t find a ton of big grocery stores nearby, though a few marinas have small convenience shops for the basics.
Oh, and don’t forget sunscreen.
The water’s so clear, you’ll roast before you even realize it.
