Northern Ohio River Region
Many of the following are basically a continuation of Cincinnati across the river into Kentucky from Ohio.
Kentucky's Northern Ohio River Region, better known to locals as Northern Kentucky is where the North meets the South. From the very urban cities of Ludlow, Covington,Newport, Bellevue, and Dayton (not to be confused with Dayton Ohio) which are virtually an extension of Cincinnati down to the start of the rolling bluegrass country and horse farms, the region is a surprisingly diverse one.
The terrain is very hilly, particularly near Cincinnati. This provides many famous vantage points of that city, including Covington's Devou Park, a once notorious stretch of I-75/I-71, The Cut-in-the-Hill with one of the most stunning views of any urban area, and finally the many vistas one gets while travelling around I-275 from I-471 to I-71/I-75. A particularly spectacular vista that is less known can be found where I-275 crosses the Licking River right after the exit for KY 9 and the AA Highway, its a stunning view that may cause accidents due to drivers rubber necking to see the hills of the Licking River Valley give way to Cincinnati's famous skyline on the horizon.
Accents and culture gradually get more northern as you head north. Many people in the suburbs of Cincinnati are transplants from that city, whereas some of the outlying areas have everything you'd expect from the south. A cool landmark signifying the beginning of these southern accents is the Florence Y'All water tower in Florence.
The urban areas near Cincinnati are worthy of envy of that city. While Cincinnati has long struggled with revitalizing its core, the riverfront communities particularly Newport have profited from their larger neighbor to the north's years of ineptitude (though, lately, Cincinnati is starting to catch up). The historic architecture is stunning in these areas, looking more East Coast than Southern or Midwestern and generally better preserved (though smaller) than in Cincinnati.
American English is the language of choice. You'll hear more Northern, Midwestern accents as you head closer to Cincinnati, and more Southern ones away from the city.
One area attraction (in)famous around the country is the Creation Museum just outside Hebron.
A less controversial attraction is the Newport Aquarium on the riverfront in Newport.
Auto racing fans can take in races at Kentucky Speedway in Sparta. It has hosted NASCAR racing since 2000; in 2011, it became the first new track in NASCAR's Sprint Cup Series in a decade. It also hosted IndyCar racing from 2000 to 2011, but that series no longer visits the track.
Newport offers the most lively nightlife in the region with such places as the Hofbräuhaus Newport and Arnie's. Covington also has a strong nightlife centered around its historic German district Mainstrasse Village. The area is also well known amongst Ohioans as a place where alcohol laws are looser, as a result there are many large liquor stores immediately across the river.
