Rialto Harbor's deep water entrance is located at mile 119 on the Okeechobee Waterway in Southwest Florida. We are 2.5 nautical miles West of the Alva bridge and 2 nautical miles East of the Franklin Lock. For West bound boats, the Captiva / Sanibel Barrier Islands are a pleasant days run from our docks. For East bound boats, we are a great place to re-provision before crossing Lake Okeechobee. Call us on VHF channel 16.
