People picture Los Angeles as a ribbon of eight-lane freeways running flat to the ocean. The reality on the ground is quite different, and it weighs directly on the choice between a campervan and a coachbuilt motorhome.
Los Angeles, a Region More Rugged Than It Looks
The metropolitan area is ringed by terrain that does more than close off the skyline: the San Gabriel Mountains to the north and the Santa Monica Mountains to the west push right into the urban fabric. Coastal canyons climb from the shoreline toward the heart of the city, creating roads that snake between hills just a few kilometres from the big boulevards.
The elevation gap gives a sense of the terrain: you go from sea level to over 3,000 m in the San Gabriels, sometimes in under an hour's drive. In between lies a patchwork of passes, switchbacks and ridge roads that have nothing to do with the straight Californian line you picture from the plane.
This topography changes things for anyone renting a motorhome or campervan. Driving Highway 10 or the 101 never raises a size issue. But the moment you leave these main routes to climb toward a viewpoint, reach a mountain campground, or simply cut through a canyon to dodge traffic, the vehicle's width and length stop being a technical detail. At exactly what point? That's what the roads themselves will tell us.
Canyon and Mountain Roads That Narrow the Choice
Topanga Canyon Road and Malibu Canyon Road link the Pacific Coast Highway to the valley by cutting through the Santa Monica Mountains. These are narrow two-lane roads with a steady run of tight bends and, in places, no guardrail. Mulholland Drive, running along the ridge, adds unlit stretches and hairpins that demand a firm slowdown, day or night.
None of this is impassable. But a 7 m-plus coachbuilt motorhome negotiates it with far less margin, at a slower pace, and the driver spends more time watching the rear overhang through the switchbacks than enjoying the ocean view below. A 5.5 to 6 m campervan handles these roads with an ease a larger vehicle simply can't match.
Head to the San Gabriels and the Angeles Crest Highway (Route 2) changes character: fewer continuous tight bends, but sustained climbing and genuine mountain switchbacks. It sometimes closes in winter because of snow. Toward San Bernardino, the logic is similar: the higher you climb, the more the road demands vigilance and time.
The Nomad tip
Before taking Topanga, Malibu Canyon or Mulholland in a large coachbuilt motorhome, look at the route on a satellite map rather than a standard GPS: you'll immediately see the number of hairpin bends, something no displayed drive time ever conveys.
Parking in the City: Narrow Streets, Low Garages, Local Rules
Once you're back down from the canyon, the problem changes shape. It's no longer about negotiating a bend but about finding somewhere to leave the vehicle for the night or the afternoon.
Some Los Angeles neighbourhoods have kept a residential layout built for sedans, not motorhomes. In Venice, in parts of Santa Monica, or in Silver Lake, streets are lined with cars on both sides, which shrinks the usable width down the middle even further. A campervan slips through more or less like any tall vehicle. A coachbuilt motorhome often has to search further afield, or give up a spot that would have suited a car just fine.
Covered parking garages raise a different, more absolute problem: clearance height. Downtown and in Santa Monica, underground or covered garages typically post limits around 2 m to 2.10 m, well under a coachbuilt motorhome's height. A small campervan will generally pass through without trouble, which in practice opens up access to shopping or cultural districts where surface parking is scarce.
One last point, less visible but real: some residential streets ban overnight motorhome parking during specific hours. Better to check the local signage than to find out at 11 p.m.
Which vehicle for this trip?
For anyone planning several nights in the city or moving between Los Angeles neighbourhoods between excursions, a campervan rented through CoolDrive Nomad sidesteps most of these size and clearance constraints.

Camping in the Mountains or Nearby Desert: Terrain That Filters Vehicle Size
Head up into the hills and the problem shifts once more. In the Angeles National Forest, around Mount Wilson and along Route 2, campgrounds often have short sites, sometimes capped at 7.30 m or less depending on the location. A coachbuilt motorhome over that length can simply be turned away from certain sites, a question a campervan never has to face.
The nearby desert — Joshua Tree, the Mojave — changes the scenery but not the logic. The secondary roads leading there from Los Angeles are straightforward, with no real driving difficulty. The real squeeze comes on arrival: parking areas at points of interest offer little room to manoeuvre a large vehicle. A campervan parks easily; in a coachbuilt motorhome, it sometimes takes several attempts, or giving up on the spot closest to the trailhead.
In Big Bear or Idyllwild, mountain roads like Highway 18 or Highway 243 stay narrow, and in winter they see logging trucks, a shared road surface that leaves little margin for a large vehicle in the tightest sections.
The Nomad tip
If your route combines a stop in a mountain forest with a dip into the desert, call the campground you're aiming for to check its actual length limit: the figures listed online aren't always current.
The more a route mixes mountain and desert, the more a campervan keeps its edge.
Campervan or Coachbuilt Motorhome: What It Changes Depending on Your Itinerary
There are two ways to travel around Los Angeles, and two different answers on size. The first: a fixed base in the city, with occasional outings to a canyon or a mountain viewpoint, then back to sleep in the same spot each night. The second: a real circuit stringing together several nights in the Angeles National Forest, in Big Bear, or out toward the desert, never returning to the starting point.
In the first case, the coachbuilt motorhome holds its own. If the trip stays close to main roads and well-equipped campgrounds, with only one or two canyon detours, a larger vehicle doesn't impose a dealbreaker — it simply calls for a bit more care through the bends.
It's the second case that tips the choice. As soon as the itinerary strings together several narrow canyon or mountain roads in a row — Topanga then the Angeles Crest, or a loop to Big Bear via Idyllwild — the campervan stops being a comfort option and becomes the logical solution. Less overhang to manage through switchbacks, fewer turn-aways at forest campground entrances, more margin in a trailhead parking area.
If your stay stays concentrated around Los Angeles and the main roads, without stringing together canyon routes, a classic motorhome offers the space of a proper vehicle without the constraints of the tightest mountain itineraries.
Frequently Asked Questions
Can you drive a large motorhome on Mulholland Drive or through the Malibu canyons?
Yes, nothing bans driving there, but these roads demand more vigilance behind the wheel of a large vehicle. The tight bends of Topanga Canyon Road or Malibu Canyon Road leave less margin for a coachbuilt motorhome, and you should expect slower driving, especially through the hairpins.
Where can you park a motorhome in Los Angeles?
A campervan parks more easily in the city. Low clearance heights in covered garages and the reduced width of some residential streets, lined with cars on both sides, clearly favour a compact size over a coachbuilt motorhome, which often has to search further afield for a spot.
Is a campervan enough to visit the mountains and desert around Los Angeles?
A campervan suits an itinerary that mixes canyons, mountains and desert in the same loop well. Its flexibility removes the hesitation on narrow roads and makes parking easier in the tight areas near desert points of interest or mountain trailheads.
Do Angeles National Forest campgrounds accept large vehicles?
It depends on the site. Some Angeles National Forest campgrounds cap the length of vehicles allowed, which can close off certain sites to a coachbuilt motorhome. It's best to check directly with the campground you're aiming for before setting out.
