We stayed at Disappointment for almost a week. It is a great place to relax and unplug from life. In the main campground loops, There is no WiFi available, No TV signals of any kind, and absolutely no cell service from any Cell service provider. We use all 3 main carriers, AT&T, Verizon, and T Mobile for service and work. The is no cell service, not even with a Cell Booster.

Overall, it is a nice park campground. There's lots of trees. It's easy for us to get in and out. Nice hiking trails. A secluded beach that rarely sees people outside of Summer.

The only downside we had was the increased amount of pollution washing up on the shoreline. It was pretty bad.

In the end, it was a really great place to unplug from the world, relax, and enjoy nature.
