Rocky freshwater pipe dive at Lake Okoboji's The Inn.
The Inn is a shore-access freshwater dive on Lake Okoboji, named for the hotel that once stood nearby. Three intake pipes guide the route, and the shoreline entry is rocky enough to reward a patient, careful start. Plan an early-summer visit before boat traffic builds, when the lake is quieter and the freshwater life around the pipes is easiest to enjoy.

Scuba Diving
Three intake pipes make it easy to navigate the freshwater profile once you are in.
Freediving
Freediving is secondary; the pipes are better as a scuba navigation aid than as a surface-only target.
Snorkeling
Snorkeling is better as a quick near-shore look than as the main plan for this rocky lake entry.
