Leave Visalia at 6:00 AM, following CA-99 south toward Bakersfield, then east through Barstow and Kingman before joining I-40 toward Williams and US-180 into Grand Canyon Village. Plan on roughly 9–10 hours of wheel time, but an RV with five people will realistically take 11–12 hours with fuel, restroom, and meal breaks. Good practical stops include the larger travel centers around Bakersfield, Barstow, and Kingman; fill the tank before the final stretch from Williams, where services become limited. Keep water and snacks aboard, and expect a tiring final approach—especially if arriving near dusk. Confirm your campground reservation and check-in instructions before leaving, since some Grand Canyon RV sites have size limits and limited late-arrival support.
After parking the RV and settling in, head to Mather Point, about 10 minutes from most Grand Canyon Village campgrounds. Its broad overlook is an easy first introduction to the South Rim, and the short paved paths make it manageable after the long drive. Arrive 30–45 minutes before sunset; in mid-September, sunset is roughly around 6:35 PM, though check the exact time and allow for traffic near the overlooks. The National Park Service entrance fee is generally about $35 per private vehicle, while an America the Beautiful pass may be better value if you will visit several national parks. Use the free Grand Canyon shuttle where practical rather than moving the RV between overlooks, and bring a jacket—the rim can feel chilly after sunset.
For an uncomplicated dinner, walk or drive to Yavapai Lodge Restaurant, usually open for breakfast, lunch, and dinner with hours varying seasonally; verify that evening’s closing time at check-in. Expect roughly $15–30 per person for a casual meal, with Southwestern and American comfort-food options. It is a convenient choice after the long drive, but service can slow during the dinner rush, so an early meal is wise. Return to the campground afterward, stock up on water for tomorrow, and keep food secured against wildlife; quiet hours commonly begin around 10:00 PM.
Start before dawn at Mather Point, one of the easiest South Rim viewpoints to reach from the village campground area. The walk from nearby parking is short, and arriving about 30–45 minutes before sunrise gives your group time to settle in; in September, sunrise is roughly 6:05–6:15 AM. Expect chilly temperatures, wind, and crowded railings at the main overlook, so bring layers and a headlamp. After sunrise, allow about 45 minutes for photographs and the first light moving across the canyon. The viewpoint itself is free with park admission, but parking fills quickly—use the park shuttle or walk rather than trying to move the RV.
From Mather Point, walk or shuttle toward Bright Angel Trail for a two- to three-hour out-and-back hike. Keep this deliberately modest: the return climb is much harder than the descent, and September sun can still be intense. A good turnaround is around the first rest area, depending on your group’s pace; carry at least two liters of water per person, snacks, sun protection, and sturdy shoes. The trailhead is near Bright Angel Lodge, and park shuttles are generally the most practical way to get there. Do not plan to reach the river and return the same morning. Afterward, take a relaxed break at the RV or village facilities before dinner.
Reserve an early dinner at El Tovar Dining Room, ideally around 5:00 or 5:30 PM; reservations are strongly recommended, especially for five people, and dinner typically runs about $30–60 per person before drinks and gratuity. The dining room is inside El Tovar Hotel, with historic lodge character and canyon views, though the best views are not guaranteed from every table. After dinner, travel to Hopi Point on Hermit Road for sunset. In September, private vehicles may be restricted on this road during daytime hours, so check the current shuttle schedule and use the park’s Red Route if operating; allow extra time because buses can queue near sunset. Arrive 30–45 minutes early for a railing spot, then stay through the canyon’s changing colors—bring a warm layer for the walk back.
Leave Grand Canyon Village around 5:00 AM for the long drive to West Yellowstone, following the planned US-180/US-191/US-89/US-20 corridor through Page, Kanab, the Salt Lake City area, and Idaho Falls. Allow 11–12 hours behind the wheel, plus fuel, meal, and restroom stops; with an RV and five people, rotating drivers and stopping every two to three hours will make the day much easier. Fill the tank before leaving, then use larger stations in Page or Kanab, where RV access is generally simpler than in smaller mountain communities. Keep snacks and water accessible, and check live road conditions before departing—late-season weather can change quickly near West Yellowstone.
After checking into your campground and giving everyone time to stretch, have an uncomplicated dinner at Canyon Street Grill on Canyon Street in West Yellowstone. It is a relaxed choice near the campground area, with meals generally running about $20–35 per person; allow roughly an hour rather than trying to make this a late night. Before returning to the RV, spend about 30 minutes at the West Yellowstone Visitor Information Center to confirm the next day’s park-road conditions, wildlife advisories, entrance logistics, and any construction or closures. The center’s hours can vary in September, so check locally or online upon arrival; if it is closed, ask the campground host for the same updates. Keep the rest of the evening quiet—tomorrow’s Yellowstone start will be much more enjoyable after an early night.
Leave West Yellowstone around 6:00 AM for West Thumb Geyser Basin, about 45 minutes away via US-20 and the Grand Loop Road. This is the right place to begin: the parking area is usually easier before midmorning, and the one-mile boardwalk loop takes about an hour. Follow the trail past Abyss Pool, Black Pool, and the lakeside vents, where steam rises against the broad blue backdrop of Yellowstone Lake. Keep everyone on the boardwalk—this ground is dangerously thin—and bring warm layers, since September mornings can be near freezing. There is no dependable café here, so pack breakfast, coffee, and water in the RV.
Drive about 45 minutes north and west to Old Faithful in the Upper Geyser Basin. Check the predicted eruption time on the visitor center display or the National Park Service app; eruptions are generally predictable within a roughly 10-minute window, but allow flexibility for traffic and wildlife stops. Spend around two hours watching the eruption and walking the nearby basin toward Castle Geyser and Morning Glory Pool. The Old Faithful Lodge Dining Room and Old Faithful Inn Bear Paw Deli are convenient lunch options, generally about $15–25 per person, though lines are common at midday. Continue roughly 15 minutes north to Grand Prismatic Spring at Midway Geyser Basin. Park only in designated spaces, then take the boardwalk across the basin; for the elevated overlook, use the separate Fairy Falls Trailhead parking area if open and if your group still has energy. Allow about 1½ hours, and expect the brightest colors when sunlight is strong—but never step off the marked trail.
From Grand Prismatic Spring, allow about 35–45 minutes to reach Madison Junction, heading toward the west entrance. This is a good unhurried final stop: pull into a legal turnout along the Madison River, stretch your legs, and scan the meadows for bison, especially in the cooler late afternoon. Keep at least 25 yards from wildlife and never stop in the roadway; traffic can back up quickly when animals appear. Finish back in West Yellowstone at Wild West Pizzeria & Saloon, a practical RV-friendly dinner close to town. Expect roughly $15–30 per person for pizza, burgers, and drinks; arrive before 6:00 PM or be prepared for a wait. September services and road access can change with weather, so check the park’s morning road report, carry extra fuel and snacks, and confirm that your RV fits designated parking areas before entering busy geyser-basin lots.
Leave West Yellowstone around 5:00 AM for the planned drive to Keystone, allowing 8–9 hours plus fuel, restroom, and meal stops. With an RV, expect slower progress through smaller towns and keep the fuel tank comfortably above half in the more remote stretches. Aim to arrive midafternoon, then park at your campground or lodging before exploring; oversize vehicles can be awkward in downtown Keystone, especially on busy September weekends.
Spend about two hours at Mount Rushmore National Memorial, entering from SD-244 and allowing time for the parking structure and walk to the grand viewing terrace. The grounds and visitor facilities are generally open from early morning into the evening, while the museum and concession areas have seasonal hours; check the official schedule that morning. Parking is typically about $10 per private vehicle, with the pass valid for a year, though RV spaces are limited—arrive before late afternoon if possible. Afterward, take the scenic Iron Mountain Road (US-16A) toward Custer, a beautiful 1½-hour drive of pigtail bridges, granite tunnels, and carefully framed views back toward the monument; check tunnel dimensions before taking the RV, as some sections are unsuitable for larger campers.
Return to Keystone for dinner at Keystone Depot Restaurant, a relaxed, practical choice for a group after a long driving day; budget roughly $20–35 per person and expect dinner service to wind down earlier than in a city. If everyone still has energy, fit in the one-hour tour at Big Thunder Gold Mine, where the historic underground setting offers a quick taste of the area’s gold-rush past—confirm the final tour time before committing, since September hours can be reduced. Otherwise, save it for the next morning, when the town is quieter and parking is easier.
Leave Keystone around 4:00 AM via US-16 toward Rapid City, then join I-90 west through Wyoming and onward toward I-80. This is an exceptionally long return—roughly 1,400–1,500 miles and 23–25 hours of driving before breaks—so plan for at least one overnight stop and rotate drivers every two to three hours. Fill the RV before leaving Keystone, carry coffee and breakfast, and keep the fuel tank above half in the wide-open stretches of Wyoming and Nebraska. Confirm the rental company’s mileage, roadside-assistance, and after-hours return policies before setting out.
If daylight and your energy level allow, take a brief 45-minute detour at the Badlands National Park scenic pullouts near Wall, ideally along the Badlands Loop Road. The park is open year-round, but sunrise-to-sunset is the sensible window for a quick stop, and the entrance fee is generally about $15–35 per private vehicle depending on the pass type. Keep this strictly to a leg-stretch and viewpoint stop rather than a hike; after the long previous day, the priority is safe progress. Wall Drug is convenient for fuel, snacks, and restrooms, though its full retail complex may not yet be open this early.
Rejoin I-90 through Rapid City and Gillette, then continue toward Casper and the I-25/I-80 connection, adjusting the overnight stop according to weather, fatigue, and RV availability. A practical first-night target is Cheyenne or Laramie, where you’ll find truck stops, supermarkets, and RV-friendly lodging; stopping earlier is the right call if the drivers are tiring. Continue the following day via I-80 across Utah, connect with I-15 through Nevada and Las Vegas, then take I-15 and CA-99 toward Visalia. Do not plan a same-day RV return: after adequate rest, complete the final leg, refuel and clean the vehicle, and return it in Visalia during the company’s agreed drop-off window.
