White water kayaking and canoeing is very popular in Rock Island State Park, and competitions are also held here during the summer. It's worth remembering, however, that certain areas are reserved for experienced sportspeople, and you should always check this beforehand before launching.
The natural sand beach of Rock Island State Park always draws a crowd when the weather is good, and the calm waters make for a very popular swimming spot for little ones. Modern bathhouses are also provided at Center Hill Lake, easily accessed from Rock Island State Park hotels.
If you're looking for something a little quieter, then fishing the rivers and lakes is a great way to spend the day. You will find excellent fishing spots at Center Hill Lake and Great Falls Lake.
