From the reviews
⭐️⭐️⭐️⭐️⭐️ 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.
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.
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.
My kids and I have been coming here for 10 years. We love the facility, activities, and staff. The current employees (referring to the holiday season of 2025) are all wonderful. We went there three times from Nov through Dec 2025 and every time they were awesome! Completely recommend!
Birthday parties at Lost Worlds
Lost Worlds hosts birthday parties — confirmed on their own site. Climbing parties come with staff who handle the harnesses and belaying, so parents can mostly watch. One thing that's different here: every guest needs a signed waiver — send the gym's waiver link to the other parents when you send invites, or check-in day gets slow. Packages, party rooms, and pricing change often, so check the current options and book ahead — weekend slots go fast at popular gyms.
