7-Day Colorado to California Road Trip

These are the key tips to help you prepare for your Colorado to California RV adventure — from timing your trip to staying safe in remote landscapes.

• Best Time to Go: May through October offers the best weather balance — after snow season in the Rockies and before peak heat in the desert. Spring and fall are ideal for smaller crowds and mild temps.
• Tolls & Entry Fees: Expect tolls near Denver. Use a mobile app or check the Colorado ExpressToll website. National and state parks charge between $10–$35 per vehicle. For unlimited access, consider the America the Beautiful Pass.
• Gas Stops & Supplies: Fill up often — especially across Utah and northern Arizona, where towns are spread out. Always keep at least half a tank and bring extra water, snacks, and a backup meal before remote stretches like Capitol Reef or Lake Powell.
• Time Zones: You’ll pass through Mountain Time (Colorado/Utah), Arizona (no daylight savings), and Pacific Time (Nevada/California). Double-check tour times and campground check-ins.
• What to Pack: From desert heat to cool mountain mornings, layers are key. For a complete list of essentials, check out our RV camping packing list.

From high elevations to desert heat, here’s how to stay safe and respectful as you explore the wild terrain between Colorado and California.

• Altitude Awareness: Denver sits at 5,280 feet, and you’ll reach even higher elevations in the Rockies. Stay hydrated, avoid alcohol on day one, and give your body time to adjust if you’re coming from sea level.
• Leave No Trace: Always follow the 7 Leave No Trace principles — stick to trails, pack out trash, and never feed wildlife. These are especially important in remote parks like Capitol Reef and Joshua Tree.
• Desert Prep: In Utah, Arizona, and Southern California, dehydration is a real risk. Pack more water than you think you’ll need, wear a hat, and avoid hiking during peak sun hours.
• Wildlife Safety: You may spot elk, bighorn sheep, or bears in Colorado. Read the National Park Service’s wildlife safety tips and always store food securely in bear country.

Camping with an RV gives you freedom, but popular destinations require some planning. Here’s how to secure your spot and stay campground-smart.

• Reserve Early: Campgrounds at Moab, Capitol Reef, Lake Powell, and Joshua Tree fill up fast. Use Recreation.gov to book ahead on public lands.
• Road Conditions: Most routes are well maintained, but always check Colorado road conditions and monitor Utah emergency updates for flash flood warnings. Cell service is limited in many areas — download offline maps.
• Quiet Hours & Etiquette: Most campgrounds enforce quiet hours between 10 p.m. and 6 a.m. Respect your neighbors by keeping noise down, lights low, and using only designated fire rings. Always pack out your trash.
• Bonus Tip: After dropping off your RV at the Los Angeles roadsurfer station, head to the coast. Don’t miss our list of the best beaches in Los Angeles for one last golden-hour moment.
