Rockland County families looking for something to do when the weather turns are getting a new option: Slick City Action Park is preparing to open a location inside the Palisades Center in West Nyack, with giant slides, air courts and other high-energy attractions aimed at birthday parties, school trips and rainy-day outings alike.
The new park's anticipated opening date has yet to be confirmed, according to Rockland Report, which notes that an exact calendar day for the grand opening has not been announced yet. The site will sit at 1000 Palisades Center Dr., Unit B404, inside the mall, according to Slick City's West Nyack listing, which touts slides and other action-packed attractions alongside air courts.
Beyond the big slides, the West Nyack page describes a dedicated soft-play zone for kids 5 and under, filled with mini slides, climbing obstacles and padded features built for the youngest visitors. The same listing pitches the location as a fit for school field trips, corporate events and team-building activities, not just birthday parties — positioning Slick City as a one-stop entertainment venue for Rockland County groups of all kinds.
What Birthday Parties Will Look Like
For families planning celebrations, Slick City's West Nyack parties page lays out some early logistics. Parties run two hours, covering both play time and time at a reserved table or room, and the company recommends booking two to four weeks in advance for the best availability, though online bookings can reportedly be made as late as two days out.
The same page spells out a refund policy worth noting before you put down a deposit: deposits can be refunded with at least eight days' notice, while cancellations made seven days or fewer before the event are non-refundable, though they can be applied toward a future date or party. Beyond those details, the evidence doesn't establish ticket prices, hours or a final operating schedule for the West Nyack site, and Rockland Report notes that visitors can track progress updates and advance tickets through Slick City's West Nyack web portal.
A Fast-Growing Chain Behind the Expansion
West Nyack's upcoming park is part of a much larger growth spurt for Slick City nationally. The company's first park opened in Lakewood, Colorado, in 2022, and as of this fall it had just opened its 50th attraction, in Milford, Massachusetts, according to industry outlet Blooloop. Blooloop reports the chain opened 25 locations in 2026 alone, with projections to exceed 60 open locations by the end of this year, and is targeting 120 locations by 2027.
Blooloop describes the Milford park as Slick City's first in Massachusetts, featuring 13 signature slides and attractions. But MassLive reports that location offers 15 types of indoor slides — a discrepancy between the two outlets' counts. MassLive, which covered the Milford park's official opening on October 10, also notes it includes a dedicated basketball court along with other air-court activities, and that a 90-minute ticket there costs $33.99 for visitors age 4 and older, based on the Milford park's own website.
How It Compares to Other Nearby Parks
A similar Slick City location in Manalapan, New Jersey, offers a sense of what West Nyack's lineup of attractions might eventually include, even though none of these specifics have been confirmed for Rockland County. NJ Family reports the Manalapan park has 14 indoor dry slides with names like Big Wave, Hyper Loop, Corkscrew, Tailspin, Avalanche, Riptide and the dual-lane Turbo Twin, plus an air court, a basketball court, a dodgeball court and a mini ziprail.
NJ Family also reports Manalapan's admission prices range from $33.99 for 90 minutes to $38.99 for 120 minutes, with a ten-session pass priced at $279.90, and that the park's main slides are open to riders age 4 and older, with an adult weight limit of 275 pounds. The West Nyack page lists attractions including Royal Flush, Mega Launch, Big Wave, Junior Jungle and Sport Air Court; pricing and hours for the Rockland County location remain to be announced.
For now, the Palisades Center project adds another indoor option to the county's entertainment scene, with Slick City positioning the park as a go-to destination for family outings, birthday celebrations and group activities regardless of the season. Anyone eager for firm dates or ticket details will have to keep checking back, since the company has yet to lock in a grand-opening day.
