Yosemite Mariposa County is all about peak experiences when it comes to outdoor fun. From rock climbing, hiking, and biking to water sports, the action-packed choices are literally all over the map providing adventure-seeking visitors with any number of epic venues to get their thrill on. And as the summer mercury begins to rise, there’s no better place for families to cool down than Splash-n-Dash Aqua Park.

Located on Lake McSwain in the rolling foothills of northwestern Mariposa County, Splash-n-Dash has the playful distinction of being the largest floating, inflatable water park in North America and is where giggles, grunts, and peals of delight can be heard all day long amid the floating trampolines, swings and dozens of other attractions. With two of the tallest inflatable water slides in the country — not to mention movie nights on Fridays and Saturdays, paddle boarding, kayaking, and lake view cabanas for rent — this brightly colored mecca of merriment is the perfect counterpoint to the tranquil trails of your Yosemite Mariposa County vacation.

The Splash-n-Dash Aqua Park Experience

Everything is more fun in the water, and Splash-n-Dash Aqua Park aims to thrill with a family-friendly experience providing all day activities. Newly expanded from 49,000 to 125,000 square feet, Splash-n-Dash Aqua Park is the largest inflatable water park in North America, creating an inflatable water park experience big enough for an armada of thrill-seekers.

The water beckons on Lake McSwain, and there are many ways to explore it with Splash-n-Dash Aqua park watercraft rentals. Feel that esprit de core while standing tall on a Paddle Board, slice through the ripples in a Kayak (1-person, 2-person, or child size), or leisurely tour the aqua-scape via Pedal Boat. 60-minute/4-hour/All day rentals are available at The Reel Deal Market & Cafe beginning at 9:00 am daily. All are first-come/first-served.

Cabana Rentals

Everybody likes to have their own designated fun space, and Splash-n-Dash obliges with cabanas for rent where families and groups of friends can set up a base camp for all the action. Options include the Water View Cabana Rental — a 10’ x 20’ gazebo with views of the lake that seats 8+ people on cushioned couches, chairs & ottomans — and the regular Cabana Rental which features the same comforts sans the view. Both options also provide a cooler with 16 lbs. of ice, a table and personalized service from a Splash-n-Dash team member who will check to make sure the party has officially started! For those who want to leave the cooking to someone else, food & beverage service is provided for an additional fee. If something more intimate is desired, Splash-n-Dash also offers Premier Seating — two cushioned loungers and table situated cozily beneath a shade canopy.

NOTE: Splash-n-Dash offers complete birthday party packages that fit all ages that include food and fun goodies for all to be enjoyed in your own picnic area. Click here to learn more about Birthday Party Packages and larger Group Gatherings.

Stay & Play (aka Splash & Crash)

Nobody wants to make the long drive home after an action-packed day on the water, especially when you’re at the footstep of America’s most majestic outdoor playground — Yosemite National Park. Visitors can take it easy by setting up a base camp surrounded by stunning outdoor recreation, whether that’s a tent or a comfy hotel in one of the charming Gold Rush towns nearby. Hiking, history, water sports….when it comes to a balanced diet of vacation fun, Yosemite Mariposa County has it all.

Safe Splashin’

Safety comes first at Splash-n-Dash – literally. Before even getting in the water all guests undergo a safety orientation and review park rules. Then once guests are in the water they’re required to wear U.S. Coast Guard-approved life jackets which are supplied free of charge. Aqua shoes are required to prevent any accidental slips off slides and equipment, visitors can bring their own or purchase aqua shoes on site.

Splash-n-Dash employees are trained to always take care of and respect guests’ every need. In total, there are 37 employees at Splash-n-Dash and every staff member that tends an inflatable object is a certified lifeguard. Splash-n-Dash always exceeds the standard ratio of lifeguards to swimmers.
