Wow! A majestic and beautiful place. The only downside is that there is always a lot of people. Fishing here is top notch and we have seen bears on several of our trips (so be prepared;)
Hidden lake campground is a family friendly campground. Located on the kenai peninsula, you are sure to see some awesome wildlife. Lots of hiking and water sports at this campground. They have some larger sights for bigger groups and it's a great place to go to get away. Not close to anything, so take anything you might need for you trip!
The park is well maintained and clean. Lots of different areas to hike and explore. They do have sites available that haves shelter with screen door and picnic table inside a huge bonus to get out of the sun and bugs. I would say this is a pretty good campground for Texas :) I'm just used to Alaska and Oregon camping which is a bit different and more adventurous (in my opinion)
