Lost Worlds Adventures

Lost Worlds is located in Livermore, California, in the East Bay area, situated off Patterson Pass Road in a commercial district near the Altamont Pass.

Where Prehistoric Thrills Meet Modern Play

Lost Worlds is a 45,000-square-foot indoor family entertainment center that brings a dinosaur-themed universe to life. Unlike a typical arcade or playground, this venue is fully immersed in a prehistoric aesthetic — from the moment you walk in, you are surrounded by dinosaur motifs, ancient rock formations, and a color palette that feels like stepping into a Jurassic-era adventure. The space is designed to feel expansive and exploratory, with distinct zones for different activities, all tied together by the overarching theme. It is a place where the imagination of a child (and the inner child of any adult) can run wild among giant fossils and jungle-inspired decor.

Eight Attractions Under One Roof

The center boasts eight distinct attractions, making it a versatile destination for a full day of play. The centerpiece is the Dino Play Structure, a multi-level soft play area with slides, tunnels, trampolines, and a ball pit, designed for younger adventurers to burn off energy in a safe environment. For those seeking a competitive edge, the Laser Tag Arena is a multi-level, high-tech battleground with prehistoric theming, where players can team up or face off in fast-paced rounds. The Black Light Mini Golf course winds through a glow-in-the-dark prehistoric landscape, complete with obstacles and challenges that glow under UV light. Active kids and adults alike will enjoy the Ninja Course, which tests agility and strength with a series of obstacles, as well as the Climbing Walls designed to resemble ancient rock faces with varying difficulty levels. Additional attractions include Mini Bowling, an Aerial Course, and a Prehistoric Arcade featuring over 50 games, including VR experiences and prize redemption machines.

More Than Just Open Play: Events and Gatherings

Lost Worlds is particularly well-suited for celebrations and group events. The venue offers dedicated party packages that include a private party room, a dedicated host, and food service, making it a stress-free option for parents planning a birthday party. The packages are designed to accommodate different group sizes and preferences, with options that include varying combinations of attractions, laser tag rounds, and dining time. Beyond birthdays, the facility is also available for corporate gatherings, team-building events, school field trips, and grad nights. The spacious layout and variety of activities make it a solid choice for groups looking for an engaging, all-in-one entertainment experience where guests can mix and mingle across different attractions.

A Place for Parents, Too

While the venue is clearly geared toward children, it is designed with parents and caregivers in mind. There is a lounge area where adults can relax while keeping an eye on their kids, and the on-site cafeteria serves pizza, hot dogs, snacks, and drinks, so there is no need to pack a lunch or leave the premises. The staff are described as friendly and helpful, and the facility is set up to handle walk-in guests as well as booked parties. Many visitors note that the venue works well for a wide age range — from toddlers exploring the soft play structure to older kids and teens enjoying laser tag and the ninja course. Some reviewers suggest that the sweet spot is ages 4 to 10, but the variety of attractions means there is something for nearly everyone in the family.

What to Know Before You Go

Lost Worlds is an indoor facility, making it a great option for rainy days or hot afternoons when outdoor activities are less appealing. The venue requires socks for the play areas (safety socks can be purchased on-site if forgotten). Weekday afternoons tend to be quieter, while weekends can get busy with birthday parties and families. The facility is walk-in friendly, but booking tickets or party packages online in advance is recommended to secure your spot and skip the line. The center is located in a commercial area with ample parking, and it is easily accessible from the freeway.
