Prior to
European Settlement, the area was used by the
Neutral Nation. At Rondeau, the cottage leases were first created between 1894 and 1950. As of 2022 there are 278 private cottages within Rondeau Provincial Park. The future of cottages at Rondeau has been controversial. In 1986, the Provincial Parks Council recommended the extension of all cottage leases to 2017 after which they would be terminated, Since 1954, the Rondeau Cottagers Association has been lobbying for recognition and preservation of the Rondeau cottage community. In 2014,
Chatham-Kent Council voted to have Rondeau's cottage community placed on the municipality's Heritage Register and be designated as a heritage district; the designation was later repealed by an order from the
Ontario Municipal Board but the community remains on the Heritage Register. A formerly popular site in the park was the government pier on Rondeau Bay. In 2014, the pier was severely damaged by thick ice on Rondeau Bay and later removed. Despite community pressure, the pier has not been replaced. The Rondeau Yacht Club, located within the park, was founded in 1932. The club continues to operate during July and August teaching sailing, windsurfing, canoeing, and swimming to area children. == Natural environment ==
