Car Rental Planning Tips

Book in Advance: Reserve your rental car early, especially during peak seasons like summer and ski season, to secure the best rates and vehicle availability.

Fuel Up Before Heading Out: Gas stations can be sparse in mountain areas. Fill your tank in urban areas and consider carrying extra fuel for remote drives.

Check Road Conditions: Mountain roads may require chains or have closures. Visit cotrip.org for real-time Colorado road conditions and alerts.

Avoid Rush Hours: I-25 and US-36 can get congested. Plan your departures to avoid weekday rush hours (7-9 AM and 4-6 PM) for a smoother drive.

Understand Rental Insurance: Review your credit card and auto insurance coverage before buying extra rental car insurance to avoid unnecessary costs.

Download Offline Maps: Cell service is unreliable in national parks and mountain passes. Download offline maps from Google Maps or use a dedicated GPS device.

Prepare for Winter Driving: If renting between October and April, ensure your vehicle has snow tires or all-wheel drive. Pack emergency supplies like blankets and a shovel.
