Dive into an enchanting Underwater Adventure with these styling ideas for pool parties, beach days, beachside parks, or home gatherings. Use shades of aqua and turquoise, with pops of colour such as greens, oranges and yellows as your colour palette. Layer in vibrant seashell decorations, netting, and treasure chests around ocean-inspired snacks, and you’ve got yourself an underwater wonderland!

1. Beach Parties

**Picnic at the Beach**

Create the perfect setting with a white, nude or tan picnic mat decorated with pillows, seashells and driftwood. Use bubble machines near the entry area to set a magical underwater atmosphere as guests arrive. Use artificial coral, fish and the Bees Party Packs supplies as stunning pops of colour to bring the theme to life.

2. In your Backyard

Backyard parties are a great option for flexibility and ease!

Turn your backyard into an underwater realm with a pale blue tablecloth layered with fish netting and scattered shells to set the scene for a magical kids’ party. Use a simple table layout: place the Underwater Adventure party pack, centre a treasure chest filled with chocolate coins and small toys, and dot the table with starfish and coral accents. Add inflatable whales and sharks around seating areas for playful props, and anchor the space with balloons in aqua, navy and pearlescent white to mimic bubbles. An underwater backdrop against a wall or fence instantly transforms the area for photos and gives a cohesive look that ties all your decorations together. Take a look at our Underwater Adventure Photobooth Props below.

Keep the fun interactive with face painting as the main activity — kids love emerging as mermaids, fish, sharks or seahorses. Set up a shaded station with a mirror, safe face paints and a simple design chart so children can choose their look. Consider hiring a friendly painter or asking a patient helper to manage the queue. With music playing soft ocean sounds and a few sea-themed games, the party will feel immersive and memorable while staying easy for parents to host at home.

3. At the Park

**Parkland Parties**

Parks and other recreational facilities offer more space and activities.

An underwater kids’ birthday at a beachside park turns the shore into a lively marine playground. Turquoise tablecloths ripple across picnic tables; blue and green balloons bob like shallow and deep waters. Ocean-shaped balloons such as dolphins, turtles and shimmering fish catch the sun and will delight the children. Bubbles drift over sandcastles and games, adding a festive, whimsical, enchanted touch.

The birthday child can wear a shell crown, making them king or queen of the sea, while friends wear party hats and gather for games and cake. The beach/park setting lets kids play in the sand and grass, and shaded spots give parents a comfy place to relax and serve picnic food. Simple sea-themed decorations and a few bubbles ought to keep setup and cleanup easy, leaving bright photos and happy seaside memories.

4. Pool Parties

Let the fun begin with an Underwater Adventure pool party!

Start with a bold colour base: drape tables in either turquoise or bright orange tablecloths to create instant underwater or sunset-over-the-sea vibes. Style with Bees Party Packs’ Underwater Adventure themed table supplies. Place textured coral centrepieces down the length of each table; choose foam or paper versions that mimic real coral shapes for playful height and bursts of colour. Scatter shells, faux pearls and small starfish around the bases to reinforce the marine theme and give little hands fun things to examine.

Hang an array of garlands and lanterns above the pool and seating areas to tie the whole space together. String fish and sea creature garlands along fences and between umbrellas, and intersperse beach ball garlands for a playful, summery touch. Suspend colourful orange and blue paper lanterns at varying heights to create movement and soft lighting as the afternoon fades. Finish with a sand-and-seashell craft station—to keep kids engaged while maintaining the cohesive underwater-party look.

5. Picture Perfect Backdrops

**Personalised Backdrops**

Create an eye-catching photo backdrop for an underwater adventure kids' party featuring a deep-sea scene with layered blue gradients, playful coral reefs, swaying seaweed, and friendly marine life like clownfish, turtles and a smiling octopus; include bubbles, sunbeams filtering through the water and a sandy seabed to add depth. Choose durable, matte-finish material to avoid glare under party lighting while allowing room for personalised signage or props such as snorkel masks, treasure chests and inflatable sea creatures for interactive photo moments. Take a peek at our Underwater Adventure Photobooth Props below.

Photo backdrop perfect for the beach or beachside park!

Set up a large ombré fabric in blues or nudes in a lightly shaded area to make the most of some great natural lighting without having your guests squinting in their photos… This will enhance the experience while capturing magical memories.

For a simple yet effective backdrop, drape the fabric with layered netting and decorate with faux starfish, small plastic fish, and weave in strings of pearl beads. Lay a tan rug on the floor area in front of the backdrop. Scatter larger shells, and a few plush sea creatures such as an octopus, whale and turtle on the rug for the finishing touches.

6. Food Fit for an Underwater Adventure

To style an underwater themed food table, think of low tables or crates. Paint in driftwood grey for cake and treats, and accent with greenery to suggest seaweed made of crepe paper or fabric. Style the table with a natural linen or sand-coloured cloth as the table covering and an aqua gauze or netting runner. Use Bees Party Packs’ Underwater Adventure tableware, and centrepieces of glass jars or vases filled with sand and a battery-operated tealight candle. Decorate further with small plastic crabs, seahorses and other small sea creatures. Place settings can feature name tags on kraft paper cut into shell or fish shapes. Repeat the driftwood grey, sand tones and aqua accents across the table for a cohesive seaside look that’s safe and child-friendly.

Alternatively, drape the table in layered blue netting to mimic rippling water, then scatter faux pearls and glittering shells around a slightly opened treasure chest overflowing with gold-wrapped chocolate coins and tiny glass bottles of "message" scrolls. Arrange underwater-inspired treats in varied heights: bowls of shimmering blue jelly topped with gummy fish, skewers of "seaweed" made from thinly sliced cucumber or green fruit straps. Add platters of cakes and cupcakes iced and adorned as friendly sea creatures, starfish, coral and shells using fondant, edible glitter and chocolate seashells. Finish with frosted sand made from crushed biscuits and a few battery-operated tealights tucked beneath the netting to give the whole spread a soft, sunlit-from-below glow.
