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. The staff was friendly, patient, and very helpful throughout the party. They made sure the kids were having fun and helped keep the schedule on track, which made a big difference. The party setup, food, and overall coordination were excellent, and all the kids had an amazing time..
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. We do go to the other area with the ball pit, but he’s gotten knocked down by the older kids in the area and I feel that could be avoided if there were a ball pit in the toddler playground; It looks like there is space for maybe a small inflatable pool sized one. Just wish they had it. I also wish toys in the toddler area were not broken, and that there were better lighting in the tunnel, too. On busy days one diaper changing station is not enough.
Very small play areas and pretty expensive for the activities they have. If they keep the entire area for $25 or something, then it is fine. But they decided to split the small area into further smaller partitions and charge extra 😇. A Small play area plus mini golf for $26. Small ninja area plus something else for $26 and so on. If you want to experience all, you’ve to pay more than $40. We wanted play area, but we were not interested in mini golf. Still we have to pay $26. On top of this, they charge $5 for the parent who go with the kid just to be in their space. And if you don’t have their socks, you’ve to pay another $4 or $5. Even though we had socks from another trampoline park with proper grips, they were not ok with it. Yeah that can be part of safety policy, but the overall charge is still ridiculous. To add to it, they don’t follow safety protocols properly. There was literally no one monitoring the ninja area for the 1 hour we were there. There was just one guy who was busy with kids in the rock climbing area and no one cared about the kids playing in the ninja area. Anyway since the price was high or whatever, there were only a very few kids who was using this place. So parents were able to manage it.
I recently threw my daughter Ellie’s 4th birthday party, and it was such a fantastic experience from start to finish. From the moment we arrived, party check-in was incredibly easy and stress-free, which set a great tone for the day. We were given a large, decorated party room with dinosaur plates which was a nice touch, perfect for celebrating and accommodating all the kids and adults comfortably. The service throughout the entire party was amazing, the party host was wonderful with the children, keeping everything organized and fun, and the rest of the staff was just as great, friendly, and attentive. The food was also amazing, which both the kids and adults really enjoyed. Overall, Lost Worlds Adventures went above and beyond to make Ellie’s birthday so special. It was well organized, fun, and truly effortless. We couldn’t have asked for a better place to celebrate, and we highly recommend it for anyone planning a kids’ birthday party.
