Otter Mound Preserve

Otter Mound is located at 1831 Addison Court, Marco Island. The 2.45 acre preserve is located in southwestern Collier County in a residential area of Marco Island, known locally as the Indian Hills section. The preserve is maintained by Collier County. The preserve is named for a previous resident, Ernest Otter a one-time owner who had occupied the property until 1997. Otter is credited for the unique whelk shell terraces that define the preserve’s signature man-made feature. The initial preserve was established with a 1.77 acre purchase in 2004 followed by an additional acquisition of .68 acres in 2007.
