1) Think twice before renting a car in Denver

It is pretty easy to get around Denver by public transport. Parking in the city is usually paid and quite expensive. If you plan not to travel out of the city a lot, there is no necessity in a car.

2) Head to Civic Center Park in Denver fasting

When you walk around Civic Center Park in Denver, you are likely to come across plenty of food trucks. BBQ, pizza, sushi and Indian food are available. And, of course, the best tables are on the grass.

3) Try to avoid two districts in Denver after dark

When walking in Denver in the evening, choose any area, except for Aurora and Colfax Avenue. These areas can be pretty wild sometimes depending on the time of day and how active thieves are. Some locals state being a witness of unpleasant stories in daylight on Colfax.
