On Carnival ships, the Serenity Deck is officially known as the Serenity Adult‑Only Retreat. It is a peaceful, outdoor sun deck.

This area is reserved exclusively for guests aged 21 and up.

Here’s what makes it special:

What Is It?

• A free, adults‑only relaxation zone separate from the main pools, where children are not permitted  .
• Decorated in a calming palette—teal cushions, black/wicker furniture, and shaded umbrellas  .
• Heated at no extra charge; seating—hammocks, loungers, clamshells, daybeds—is available first-come, first-served  .

Amenities & Features

• Hot tubs/whirlpools on almost every ship (usually two; sometimes cantilevered with ocean views)  .
• Selected ships (Celebration, Jubilee, Legend, Miracle, Pride, Spirit, Splendor, Sunshine, Mardi Gras) include a small pool too  .
• Numerous ships offer a ”Fresh Creations” salad station for light bites—think made-to-order salads  .
• A full Serenity Bar serves cocktails, beer, sangria, wine, frozen drinks, smoothies, etc., at regular prices  .
• Dedicated facilities: shaded seating, showers, restrooms, towel attendants

Location & Layout

• Found on every Carnival ship, with layouts varying wildly—some multi-level, others compact  .
• Aft locations (e.g., Pride, Legend, Splendor, Spirit) tend to offer quieter vibes and better ocean views  .
• Forward decks may experience more wind and some sound drift from nearby water parks ().

Guest Tips

• No reservations for seating. Loungers and daybeds are open to all. However, beach towels don’t hold spots for long. The crew usually clears them after about 40 minutes.
• Visit early (often around 7–8 AM) for the best picks in sea-day serenity  .
• Bar & whirlpools typically operate ~8 AM–10 PM  .
• Clothing is required—no topless or nude sunbathing allowed,
