Doing a week-long road trip doesn’t have to drain your bank account. With smart planning we discovered, free camping, strategic meal prep, and a few insider tricks, you can spend seven days exploring scenic highways and back roads for under $500 per person as we did. Here’s exactly how to do it with a realistic day-by-day budget breakdown.
The $500 budget breakdown
| Category | 7-Day Total | Per Day |
|---|---|---|
| Gas (1,500 miles total) | $150–$180 | $21–$26 |
| Food & drinks | $140–$175 | $20–$25 |
| Camping / accommodation | $0–$70 | $0–$10 |
| Activities & misc | $30–$75 | $4–$11 |
| Total | $320–$500 | $45–$71 |
Gas: the biggest expense (and how to control it)
At current fuel prices, a car getting 30 mpg covering 200 miles per day will burn roughly $20–$25 in gas daily. That’s our major single largest cost, and there are several ways to reduce it.
Use GasBuddy or Waze to find the cheapest stations along your route — prices can vary by $0.50 per gallon within a few miles, especially near highway exits. Fill up at warehouse clubs if you have a membership. Drive at 60–65 mph instead of 75 — the fuel efficiency difference at highway speeds is significant, saving roughly 15% per tank. Keep your tires properly inflated and avoid running the AC at full blast on cooler days.
Food: meal prep is your secret weapon
Eating out three times a day will blow your budget by day three. Instead, pack a cooler and plan your meals.
Before departure: Buy bread, peanut butter, trail mix, fruit, granola bars, and instant oatmeal packets. This covers breakfasts and lunches for the entire week for under $30.
On the road: Splurge on one restaurant meal per day — dinner at a local diner is both affordable and part of the experience. Budget $10–$15 per dinner. Cook simple campfire or camp stove meals for the nights you want to save more: pasta, canned soup, rice and beans, or hot dogs are all cheap and filling.
Water: Bring refillable bottles and fill them at every gas station, rest stop, and campground. Buying bottled water adds up shockingly fast over a week.
Accommodation: sleep free (legally)
This is where budget road trippers save the most money. You don’t need to pay $100+ per night for a motel when America is full of free and cheap sleeping options.
BLM (Bureau of Land Management) land: Across the western US, millions of acres of BLM land are open for free dispersed camping. No reservation, no fee — just pull off on a designated dirt road and set up camp. The FreeRoam or iOverlander apps show verified free camping locations with reviews.
National Forest dispersed camping: Similar to BLM land, most national forests allow free camping outside developed campgrounds. You typically need to be 100 feet from water and roads, and practice Leave No Trace principles.
Walmart parking lots: Many Walmart locations allow overnight parking. It’s not glamorous, but it’s free, safe, well-lit, and has a bathroom. Call ahead to confirm the specific store allows it — policies vary by location.
Rest stops: Some states allow overnight parking at rest areas; others have time limits. Check state-specific rules. At minimum, rest stops offer a safe place for a few hours of sleep in your car between driving legs.
Gear tip: You don’t need expensive camping equipment. A $30 sleeping bag, a $20 foam pad, and your car’s back seat (with the seats folded down) is a perfectly functional road trip sleep setup. If you have a tent, a basic $50 model works fine for fair-weather summer trips.
Free and cheap activities
The best things to do on a road trip are overwhelmingly free. Scenic overlooks cost nothing. Hiking trails are free on public land. Swimming in rivers and lakes is free. Watching sunsets from your campsite is the best entertainment money can’t buy.
National Parks charge $30–$35 per vehicle — worth it for a full day but not if you’re just passing through. National Forests and BLM recreation areas are usually free. State parks vary from free to $10. Many museums offer free admission days — check in advance.
If you plan to visit multiple National Parks, the $80 America the Beautiful annual pass pays for itself after three parks and covers all 400+ NPS units.
A sample 7-day budget road trip

Day 1: Denver to RMNP — drive Trail Ridge Road, camp free in Arapaho National Forest. Spend: $25 gas + $0 camp + $12 food = $37.
Day 2: RMNP to Grand Junction via Glenwood Canyon — swim at Hanging Lake area, camp on BLM land near Fruita. Spend: $30 gas + $0 camp + $15 food = $45.
Day 3: Grand Junction to Moab — drive the scenic Colorado River corridor, hike in Arches NP. Spend: $20 gas + $35 park pass + $12 food = $67.
Day 4: Moab — full day in Canyonlands, camp on BLM land. Spend: $10 gas + $0 camp + $15 food = $25.
Day 5: Moab to Grand Canyon via Monument Valley — the most epic driving day. Camp in Kaibab NF (free). Spend: $35 gas + $0 camp + $12 food = $47.
Day 6: Grand Canyon — full day on the South Rim (covered by your parks pass), camp in Kaibab NF. Spend: $5 gas + $0 camp + $20 food (treat yourself to a sit-down dinner) = $25.
Day 7: Grand Canyon to Denver via Flagstaff and I-40/I-25 — long drive home. Spend: $40 gas + $15 food = $55.
