Most AI trip planners are built for the “fly somewhere, stay in a hotel, see the sights” traveler. What if you want to do a road trip — a real multi-city, rental-car, scenic-route road trip? Most AI tools fall apart. Curiosio is the exception. It’s built specifically for road trips, and the AI optimises routes based on scenic value, EV charging locations, accommodation quality, and the kind of detours you actually care about.
What is Curiosio?
Curiosio is an AI road-trip planner designed for multi-city, multi-day driving holidays. You enter your start and end points, optional waypoints, and travel preferences, and the AI designs a route with scenic stops, overnight locations, attractions along the way, and detailed drive-time estimates. Unlike Google Maps, which gives you the fastest route, Curiosio gives you the best experience — factoring in things like “avoid highways where possible” or “take the coast road even if it’s longer.”
It’s particularly popular with European and North American road trippers, EV owners (it includes charging stop optimisation), and people planning cross-country adventures.
My test: a California coast road trip
I ran Curiosio against a classic test: San Francisco to Los Angeles via the Pacific Coast Highway, 5 days, stopping at Big Sur and San Luis Obispo, interested in scenic overlooks and good food. Here’s what it gave me:
Day 1: SF → Half Moon Bay → Santa Cruz (overnight). Recommended beach stops and a specific clam chowder place I’d never heard of.
Day 2: Santa Cruz → Monterey → 17-Mile Drive → Carmel (overnight). Highlighted a scenic pull-off that’s not on the default PCH route.
Day 3: Carmel → Big Sur → McWay Falls → Julia Pfeiffer Burns State Park → Ragged Point (overnight). This is where Curiosio earned its keep — it timed the Big Sur drive to avoid afternoon fog based on historical data.
Day 4: Ragged Point → Hearst Castle → San Luis Obispo → Pismo Beach (overnight). Included a lunch stop at a family-owned taqueria with specific hours.
Day 5: Pismo → Santa Barbara → LA. Recommended a wine detour if I had time.
Every segment had drive times, fuel stops, and scenic recommendations. It felt like a plan from a friend who actually drives the PCH regularly, not a generic AI output.
Where Curiosio shines
Route optimisation for scenic value. This is the main reason to use it. Google Maps optimises for time. Curiosio optimises for experience. You can set preferences like “avoid highways” or “prefer coastal routes” and it actually respects them.
EV charging stops. If you’re driving an electric car, Curiosio plots charging stops based on your battery range and real charger availability. Much better than trying to do this manually in Google Maps.
Multi-stop accommodation planning. For a 5-day road trip you need 4 overnight stops. Curiosio recommends towns based on distance, amenities, and attractions — not just the closest hotel. It tries to balance drive time across days.
Scenic pull-offs and viewpoints. Curiosio surfaces lesser-known viewpoints along your route. Things like “best photo stop on the PCH north of Big Sur” show up as numbered stops in the plan. Real local knowledge baked in.
Budget estimator. Factors in gas, accommodation, food, and attractions into a total trip budget. Useful for reality checks.
Where it stumbles
Coverage is uneven. Excellent for the US, Western Europe, Iceland, and New Zealand. Much weaker for Eastern Europe, Asia, Africa, and Latin America. The AI models have much less data to work from in underserved regions.
UI is cluttered. Curiosio’s interface shows a lot of information at once, and it can overwhelm first-time users. The learning curve is steeper than iPlan.ai or Wonderplan.
Not for city-only trips. If your trip is “5 days in Rome,” Curiosio is the wrong tool. It’s designed for driving between places, not for exploring one place.
Freemium limitations. You get a few route generations free, then need a subscription. Fair enough, but the cap hits quickly if you’re comparison-shopping routes.
Occasional stale data. Some accommodation suggestions are outdated (places closed or changed names). Always cross-check.
Road trip scenarios where Curiosio really earns its keep
Scottish Highlands loop. A classic road trip with too many scenic detours to plan manually. Curiosio’s Highlands routing is genuinely better than anything I’ve found in a guidebook.
Iceland ring road. Curiosio knows which parts of the ring road are worth stopping at and which are just driving. It also factors in seasonal closures.
Cross-country EV trip in the US. The charging stop optimisation is invaluable here. Doing it manually across 10 states is a nightmare.
Alps region (Austria/Switzerland/Italy). Mountain passes, seasonal roads, and scenic overlooks — Curiosio handles this complexity well.
Pacific Coast Highway. My California test was a pleasure.
Pro tips
Set your priorities clearly. “Scenic over fast” is the most important preference to get right. Also consider “avoid backtracking,” “prefer small towns,” and “limit daily drive time to 4 hours.”
Use the waypoint feature. If there’s a specific place you want to visit, add it as a waypoint before generating. Curiosio will route around it.
Check the drive times manually. Curiosio’s estimates are usually good but occasionally underestimate mountain or rural roads by 20-30%. Sanity-check with Google Maps.
Cross-check accommodation. Curiosio recommends hotels and B&Bs, but verify prices and availability on Booking.com or direct before assuming anything.
Download the offline map. For rural road trips, cell coverage is unreliable. Always have Google Maps offline loaded as a backup.
Verdict
Curiosio is the best AI tool I’ve found for road-trip planning, full stop. It’s not for everyone — city-break travelers should ignore it — but if you’re planning a multi-day driving holiday, especially in a region where scenic routing matters, it’s worth dealing with the UI quirks and learning curve.
For everything else (city trips, flight-based travel, solo backpacking), use one of the other AI planners in the directory. Use the right tool for the right trip.
