Katie Ledecky. Michael Phelps. Chase Kalisz. The D.C. area knows how to produce Olympic swimmers. Whether your little ones are destined for the same fate remains to be seen, but there’s no time like the present to get them in the water, even if the temperatures outside are in the single digits. Here’s a look at some of the best (and not too cold) indoor watering holes in the area.

Barry Farm Aquatic Center

Formerly an outdoor pool and reopened as an indoor one a few years ago, it has the only indoor waterslide – did we mention it’s twisty? – in D.C.’s Ward 8. The 8,800-square-foot facility includes a six-lane lap pool and a leisure pool with beach entry.

Cost: Free/D.C. residents, swim passes for nonresidents range from $3 to $149 for day, 30-day and 90-day passes

Cost: Free/D.C. residents, swim passes for nonresidents range from $3 to $149 for day, 30-day and 90-day passes

Germantown Indoor Swim Center

This 60,000-square-foot place has a lot going on: a competition pool, recreation pool, hydroptherapy pools, diving platforms and waterslides...plural. Plus, the décor, with its (fake) palm trees and mini volcano, will transport you directly to the islands. Little ones can splash under a mushroom-shaped fountain or play in a separate fun zone.

Cost: $5/county resident or $8/nonresident 1-17 years old; $7/adult resident or $10/nonresident; $6/senior resident 55 and up or $10/nonresident

Eunice Kennedy Shriver and Sargent Shriver Aquatic Center

The eight-lane L-shaped main pool is divided into two 25-meter swim areas, a warm-water leisure pool, two separate hydrotherapy pools, diving platforms and – wait for it – a waterslide snaking along a wall. Claim to fame: Eleven divers who competed in the 2012 Olympics trained here.

Cost: $5/county resident or $8/nonresident 1-17 years old; $7/adult resident or $10/nonresident; $6/senior resident 55 and up or $10/nonresident

Prince George’s Sports & Learning Complex

Sure the 50-meter competition pool is impressive, but the leisure pool is where it’s at. Float along the lazy river, zip down a waterslide (you knew it was coming) and bask in the constant 84- to 86-degree temperatures. For adults, there’s also an 18-person spa with jets shooting out water heated to 102 to 104 degrees.

Cost: $8/impact area resident, $11/resident of Prince George’s and Montgomery counties, $15/nonresident
Where: 8001 Sheriff Rd. (Landover, MD)

Cub Run RECenter

The almost-5,000-square-foot leisure pool has two waterslides, including a 30-foot-high one that goes outside the building in an enclosed tube. There’s also a zero-depth water playground with climbing equipment, a small waterslide and lots of fountains.

Cost: $10/adult, $6.50/youth ages 5-18, free/child 4 and younger, $6.50/senior Mon.-Fri., $20/family up to five
Where: 4630 Stonecroft Blvd. (Chantilly, VA)

Claude Moore Recreation Center

The leisure pool here has what the website calls a “giant” waterslide, a children’s play area with playground-like equipment, a hot tub, a vortex and a lazy river. But if that’s not enough, there’s still space to free swim without having to go to the 25-yard-by-50-meter competition pool. Bonus: It’s next to the Loudoun Heritage Farm Museum, which highlights Loudoun County’s agricultural history through exhibits such as the Claude Moore Children’s Farm, an interactive exhibit where kiddos can be a “farmer for a day.”

Cost: $6/adult, $4/youth ages 3-17, $4/senior over 55, free/child 2 and younger, $16/family up to five
Where: 46105 Loudoun Park Ln. (Sterling, VA)
