Our family loved Kalyumet and there was plenty to do for everyone including some great activities for children. We enjoyed the pool the walking/hiking trails, a trip into Cooks Forest, and even spent some time at the arcade (costs money).
We plan to return but our only complaint would be the site we were in (11) and others next to it were quite far from the water and cable hookups. I ended up having to run 60ft of water hose and 50ft of cable in order to get a connection (which required a trip to Walmart). The electric was right on the site, but I can't understand why the water was so far away.
We plan to return but just wanted to let others know if you are booking in the first 2 rows plan to have a really long water connection and possibly electric as well.
