Essential RV Travel Planning

Traveling to a National Park in an RV requires preparation. Use the following tips to ensure a smooth and enjoyable experience.

Reservations and Planning

• Book Early: National Park campgrounds often fill up months or more in advance, especially for summer and holiday trips.
• Check Accessibility: Always confirm your RV's length is permitted at your chosen campground and for roads within the park. Use the park's official website to review all restrictions.
• Park Information: Download maps and relevant park information before you leave, as cell service can be non-existent within many parks.

On-Site Logistics

• Groceries and Fuel: Stock up on supplies and fuel outside the park. Prices within or near the park entrance can be significantly higher.
• Dump Stations and Water: Verify the location and operational status of dump stations and potable water sources. Not all campgrounds offer hookups.
• Leave No Trace: Follow the principles of Leave No Trace. This includes properly storing food, disposing of waste, and staying on marked trails to protect the natural environment.

Safety and Emergencies

• Emergency Contact: Ensure someone outside your travel party knows your itinerary and expected check-in dates.
• Bear Safety: Many parks, particularly in the West, require strict food storage protocols. Review the park's guidelines on keeping a bear-safe camp.
• Know Your Route: Use a reliable RV-specific GPS or map system that considers height, weight, and length restrictions on roads.
