The swimming area is not impressive. There is a dock for entering and exiting the river. There were some children swimming. I would swim there, but my wife would not. Also there is no shallow area for young children to play in the water.
Cabins are available to rent for large groups.
During the winter, it is my understanding that the cabins may be rented individually. I checked with one of the Rangers about bicycle trails. She said the trails are basically service roads. She gave me a special map. The map shows that the bicycle trail follows the same path as the hiking trails.
