The popularity of boating at the park has led to the creation of a Marina. The Marina at Caesar Creek was in the original plans for the lake. It is located down the road from the beach swimming area. It has a small concessions shop with food and drinks, fishing supplies (license needed to fish in Caesar Creek) and boat supplies. The marina also has coin op laundry for the hiker, camper, or boater.
Being that the marina is a marina it does have items for boaters. 91 Octane Gas without Ethanol is available along with a pump out station. The marina itself has 112 seasonal slips, but due to the popularity of boating at the park they fill up each year. 20% are available via a lottery in August. They also have 10 Transient Slips open each day.
Before the marina was built the water level had to be lowered in the Creek. While the water was lower the state took the opportunity to do archaeological research on the area. The study found nothing of note as the area had been searched before the lake was filled.
The marina is not the only new thing at the park. On the trail to the Horseshoe falls is a new large swinging bridge. the bridge is a nice addition to an already scenic area.
