What parents say

⭐️⭐️⭐️⭐️⭐️ We absolutely love this place! With 45,000 square feet of indoor fun, there’s so much to do for the entire family. From Black Light Mini-Golf to the massive multi-level laser tag arena and the largest super play structure in Northern California, the attractions are endless.

★★★★★ — Olga, Oct 2024

I’d give a 3.5 if I could. This place is pretty good for the older kids, but I’ve seen all the younger kids, including my son, get disappointed when they discover the toddler play area doesn’t have a ball pit.

★★★★☆ — Elizabeth, Jan 2026

We are a family of 6 and love it here, we are regulars. I would recommend going during the week when it is not so busy. As a family we love mini golf, play structure and laser tag. Cafe is good, we look forward to cherry icee, chicken strips and fries with hot nacho cheese.

★★★★★ — Kamilla, Jun 2024

We celebrated my son’s 5th birthday at Lost World, Livermore, and it was an absolutely wonderful experience! From start to finish, everything was well organized and stress-free for parents. The play area was clean, safe, and perfect for kids this age—plenty of activities to keep them engaged and excited.
