As of early 2026, parking rates at Denver International Airport (DEN) and nearby private lots like ParkDIA have seen significant increases compared to previous years. Following a major rate hike in 2022 and subsequent adjustments in late 2024 and 2025, daily rates for airport-owned garages have reached approximately $30 per day. ParkDIA, a popular off-site alternative, has also adjusted its pricing to reflect increased operating costs and demand; while it remains more affordable than the airport's on-site garages, travelers should expect to pay around $15-$18 per day for uncovered parking and upwards of $25 for covered options. These increases are part of a broader trend across major U.S. airports to cover the rising costs of maintenance, security, and the operation of shuttle services. It is highly recommended to check current rates and book your space in advance through their respective websites, as "drive-up" rates can sometimes be higher during peak holiday travel periods.
