It depends on your singularities. Someone can ride the whole day, and some get tired after a few hours. Personally, I like to travel by car. Usually, when I arrive in a new country, I take a car for rent and travel this country on a rented car. My last trip was to Ukraine. This is not a very popular place to travel, but in general I liked it. I rented a car in https://ukr-prokat.com/en/rental-cars/rent-a-car-lviv , and I traveled on this car all the western Ukraine! There is a puddle beautiful and picturesque!
