Charlotte-Genesee Lighthouse stands near the mouth of the Genesee River, where Rochester meets Lake Ontario. The stone tower dates from the early 19th century and is one of the clearest reminders that this inland city was once tied closely to lake shipping, canal traffic, and the small port community of Charlotte.
The keeper's house operates as a local history museum, and the climb up the tower gives a good, unfussy view over the river, marina, and lakefront. Pair it with Ontario Beach Park or a walk along the pier; the lighthouse is most rewarding when you treat it as part of Rochester's north-end waterfront rather than a quick isolated stop.
