Lava Island

If you’ve got kids who need to burn off some serious energy on a rainy Colorado day, this is the spot locals keep coming back to. The volcano climb and cliff-jumping areas give older kids something genuinely challenging, while the littles have their own enclosed zones so you’re not constantly holding your breath. It’s themed without being cheesy, and honestly, it’s one of the cleaner indoor play places you’ll find in the Englewood area — which matters a lot when you’re talking toddlers on climbing structures. Works well for birthday parties too, and the staff actually seem like they want to be there.
