Updated by Dianne Titos on March 21 2024

Whether you're going solo or on a trip or with your family, friends, or significant other, the drive along the picturesque view from California to Colorado is a guaranteed beginning of an exciting journey.

The road trip from San Diego to Denver will take about 19 hours of driving along 1,200 miles of breathtaking sceneries – from arid deserts to dense forests, through the I-70 route. The drive is long, but the opportunities for adventures are endless.

Read on and discover the best stops for rest and places to visit during your road trip from San Diego to Denver.

How far is Denver from San Diego, and how long will the road trip take?

There is a minimal difference between the two routes to Denver from San Diego in terms of driving time and distance covered.

The fastest route via I-8 will take you through Arizona's peaks and deserts, saving you only a few minutes or hours of a drive compared to the I-15 and I-70 route through Nevada and Utah. And driving through I-8 during the summer can be hellish with the unforgiving desert weather following you until you reach the bypass route to I-10 and into the outskirts of Colorado.

So unless it is winter in which some places along the I-70 are closed, taking the I-15 and I-70 from San Diego to Denver is the best route to take, offering you a view that is a feast to your senses.

Best road trip route from San Diego to Denver

The best road trip route from San Diego to Denver is ultimately the scenic route of the I-70 over the diverse topography of Utah and Colorado. It is relatively longer than taking the I-8, but the exciting sights along every step of your journey are well worth your time.

This route offers the most opportunity for exploration and adventure – whether you like climbing mountains, walking trails, or braving the waters. The long drive also lets you spend more peace and quiet with yourself or quality time with your loved ones.

Best time to go on a road trip from San Diego to Denver

As you will need to pass the Rockies on your way to Denver, you may need to consider taking your road trip in late spring to fall. Or to prepare yourself and your ride if you will be starting your journey in winter.

If you start your trip during the winter, check ahead as some parts of I-70 may close due to extreme weather conditions. You must also make sure that your vehicle is snow-ready – snow tires and snow chains, to minimize the risk of road problems.

Also, consider the traffic for your journey. The roads to Colorado may be jampacked with skiers going to the Rockies during winter.

Spring and fall are great seasons to schedule your trip because the weather is perfect for outdoor activities like hiking, biking, and fishing. It will not be too hot to walk a trail or too cold for other outdoor activities.

A summer trip can also be a good idea as well as the places on your route do not get overly hot even during this season. But, always check and consider the weather if you plan to hike as the mountain peaks' average temperature can get hot and uncomfortable.
