Have a whim to swim? Downtown's only outdoor pool overlooks Monument Circle from the roof of the Sheraton Indianapolis City Centre. There's no better poolside setting—you can see landmarks from your lounge chair. Several indoor pools are drenched in natural light and are never closed for weather. Guests at the Conrad Indianapolis relax on thick-cushioned lounge chairs and enjoy beverage service under a tall skylight that runs the full length of the tiled lap pool. The pools at the Indianapolis Marriott and Embassy Suites are set near a glass wall for a city view from an upper floor. The family-friendly swimming area at Staybridge Suites is ringed with windows, complementing the zig-zagging pool and integrated square hot tub. The Embassy Suites Indianapolis North boasts a curvy-edged ground-level pool under a soaring roof with a skylight.
Caribbean Cove at Caribbean Cove Hotel & Conference Center blows all hotel pools out of the water. This large indoor water park is attached to the hotel, allowing guests to go from lobby to lazy river in under five minutes. Three 40-foot—tall slides twist outside the building and back in—as a bonus, the colored flumes make it easy to spot the hotel from the road. Parents can soak in a hot tub and watch as a giant bucket pours its contents on kids huddled beneath, like a waterfall, or join the kids in a game of basketball in the sports activity pool.
In the northern suburb of Carmel, Doubletree Guest Suites has the city's prettiest pool environment: an ample rectangle (connected to an indoor pool) set in a flower-filled, sun-drenched courtyard with plenty of room to spread out on the patio, outfitted with chaises and shaded tables.
