Viana do Castelo – the elegant jewel of Portugal's green Costa Verde – is best explored by car, and there's good news for 2026: most of the A28 north of Porto lost its tolls in 2025, so the scenic drive north now costs only about €1.25 in electronic tolls near Porto. Most visitors rent at Porto Airport (OPO), 45–60 minutes south, where economy cars start around €10–18/day ($11–$20) in low season. This guide covers renting for Viana do Castelo: the real prices, the companies worth trusting, the toll picture, and the best drives along the northern coast.
Viana do Castelo, on the green Costa Verde, is an easy – and now almost toll-free – drive north from Porto.
Viana has no airport of its own, so most visitors rent at Porto (OPO), 45–60 minutes south, then drive up the A28. Expect roughly the following in 2026:
Average Daily Rates (Porto / Viana) by Season
Booked 4–6 weeks in advance, prices in EUR
| Season | Manual Economy | Manual Compact | Automatic Compact |
|---|---|---|---|
| Low (Nov–Feb) | €10–18 | €14–22 | €26–40 |
| Shoulder (Mar–May, Oct) | €18–28 | €22–36 | €36–52 |
| Peak (Jun–Sep) | €30–45 | €36–55 | €52–80 |
Pick up at Porto Airport for the widest fleet and best prices, then drive up the A28 (only about €1.25 in tolls).
The standard choice – the widest fleet and most competitive prices, 45–60 minutes south of Viana on the A28 (tolled only near Porto). Collect on arrival and drive north.
Viana is on the Porto–Valença rail line (Linha do Minho, about 1h10–1h45 from Porto Campanhã), so some visitors arrive by train and pick up a car locally for day trips. Hertz, Europcar and Guerin have offices in town, but the fleet is far smaller than at the airport – book ahead.
A well-rated Portuguese brand that often undercuts the global chains while keeping service high. A reliable, recognisable choice for the north.
The strongest international brand at Porto for a newer fleet and a predictable process. Pricier; watch the upsell.
A dependable major with a broad fleet and good automatic availability – a safe fallback at OPO.
Local Porto companies frequently beat the chains on price and flexibility. Worth a direct quote alongside the comparison sites for the drive north.
Aggressive upsells, fuel and damage disputes, and one of the lowest Trustpilot scores in the industry.
Cheap online but notorious for strict fuel rules and excess disputes at return.
Low headline prices but repeated complaints over deposit holds and fuel policy. Read the terms carefully.
Basic CDW with an excess of €1,000–€1,800, blocked on your card. Tyres, glass and underbody usually excluded.
Super CDW to zero the excess is €15–25/day – €105–175 a week.
Standalone excess insurance (€4–7/day) bought before you travel covers the excluded items and refunds any excess charged. Buy it and decline the counter upsell.

Very little. Since 2025 the A28 is free north of Esposende; only two electronic gantries near Porto remain, about €1.25 in total for a car. There are no booths, so the toll is billed through the car's transponder or the rental company's toll plan.
From Porto, low-season manual economy cars start at €10–18/day ($11–$20). Shoulder season is €18–28/day and peak summer €30–45/day, with automatics more.
The town centre is walkable, but a car is the best way to reach Praia do Cabedelo, the Minho region, Peneda-Gerês and the coastal villages – and the almost toll-free A28 makes it cheap to get around.
For value, Guerin and local Porto operators are excellent; Sixt and Europcar are the reliable international choices with terminal desks. Avoid Goldcar, Firefly and Klass Wagen unless you read the terms carefully.
It's cheaper to buy standalone excess insurance (€4–7/day) before you travel than the counter Super CDW (€15–25/day). Third-party cover also includes tyres, glass and underbody.
