Bemidji is a beautiful, medium sized city with interesting people. Coming into the city from the south along Highway 71, visitors become immediately aware that they are in a city and not one of the many towns along the way. The highway enters the city to the east, allowing the traveler a view of the town along the main thoroughfare "Paul Bunyan Dr." (Note from a local: the stretch of Paul Bunyan Drive between the Hampton Inn and Paul and Babe REEKS like poo, because of a sewage plant right nearby. Just make sure to keep your windows rolled up.) The prominance of the character shows as you pass the statue of the character on the right of the road, at the lake front access to Lake Bemidji. The old downtown district is to the left of the highway. A rectangular area is home to numerous shops and restaurants that cater to the city's tourist trade. The lake stretches to the north and is lined with large homes and access points and provides a wonderful view. The main road through town makes a left, leading to the major commercial center of town.
Your best bet is probably to either have a car, or know someone who does. Walking the whole city can easily be done in a day, but it's really not advisable in the winter, or in some of the more humid days of summer. Biking is a good option in the summer, there are a lot of paved bike trails to help you get around most of the city.
The Bemidji public library has free wifi, but just remember that it's not open Sundays.
