Car Rent in Cascais – Cheap Car Hire Cascais 2025

Why Rent a Car in Cascais?

Cascais is a stunning coastal town in Portugal, known for its golden beaches, historic charm, and relaxed seaside vibe. While the town itself is walkable, renting a car unlocks the full potential of your trip. With a car, you can explore hidden beaches, take scenic coastal drives, and visit nearby gems like Sintra and Cabo da Roca at your own pace.

During my travels in Portugal, renting a car in Cascais has always been a game-changer. Whether it was an impromptu detour to a secret beach or a last-minute road trip to Sintra, having a car provided the freedom to explore without relying on public transport.

In this guide, I’ll walk you through the best car rental companies in Cascais, a step-by-step guide to renting, must-know tips, and top road trip destinations.

Best Car Rental Companies in Cascais

Several international and local companies offer car rentals in Cascais, making it easy to find the right vehicle for your trip. Here are some top options:

• Europcar – Located in central Cascais and at Lisbon Airport. Well-known for its wide selection and good customer service.
• Sixt – A great option for premium cars and SUVs, with easy pickup at Lisbon Airport.
• Avis & Hertz – Reliable international brands offering both city-center and airport pickup options.
• Guerin – A reputable Portuguese company with competitive prices and good local support.

If you're arriving at Lisbon Airport (just 30 minutes from Cascais), you’ll find an even broader selection of rental providers there.

How to Rent a Car in Cascais – Step-by-Step Guide

Step 1: Compare & Book Online

Booking in advance is key to getting the best rates. I always use DiscoverCars because it lets me compare multiple providers at once and find the best deals on car rental in Cascais. Look out for early booking discounts and promo codes.

Step 2: Choose the Right Vehicle

Choosing the right car can make all the difference in your trip. If you're traveling as a couple or solo, a compact car is ideal for navigating the narrow streets of Cascais and finding parking easily. Families or larger groups might prefer an SUV or a more spacious vehicle to accommodate luggage comfortably. If you're used to driving automatic cars, keep in mind that manual transmissions are more common in Portugal, and automatics often come at a higher price. Lastly, consider your itinerary—if you're planning to venture into the rugged coastline or hilly areas like Sintra, an SUV might be a better option for handling the terrain.

Step 3: Review Rental Requirements

Before confirming your booking, take a moment to check the rental requirements. If you have an EU driver’s license, you're good to go, but non-EU travelers may need an International Driving Permit (IDP). Most rental companies require the driver to be at least 21 years old, though some charge an extra fee for drivers under 25. Also, be prepared to provide a credit card in the main driver’s name for the security deposit—debit cards are rarely accepted.

Step 4: Pick Up Your Car

You can pick up your rental in Cascais, at Lisbon Airport, or even have it delivered to your accommodation. Before driving off, it's essential to do a thorough inspection of the vehicle. Take photos or a video of any existing scratches or dents to avoid disputes when returning the car. Also, check the fuel policy—most rentals operate on a full-to-full basis, meaning you need to return the car with a full tank to avoid additional charges.

Step 5: Understand Rental Terms

Before hitting the road, familiarize yourself with the rental terms. Unlimited mileage is ideal if you plan on taking longer trips, so double-check if there are any restrictions. Additional charges may apply for GPS, extra drivers, or child seats, so factor those costs into your budget. Lastly, always save the rental company’s local emergency contact number in case you need roadside assistance.

Step 6: Drop-Off Process

Returning your car is straightforward, but there are a few things to keep in mind. Make sure you return it with the correct fuel level to avoid unnecessary refueling fees. Before handing over the keys, do a final inspection with a staff member to confirm there’s no new damage. Getting a signed receipt can help prevent any unexpected charges later on.

Essential Tips for Renting a Car in Cascais

Renting a car in Cascais has always made my trips smoother, but there are a few things I’ve learned along the way that can help you avoid common pitfalls. Here are my top tips to ensure you have the best experience with car hire in Cascais:

• Book in advance – Rental prices can fluctuate significantly, especially during peak tourist seasons. Securing your car ahead of time guarantees better rates and more vehicle choices.
• Carry required documents – Make sure you have a valid driver’s license, passport or ID, and a credit card in the driver’s name for the deposit.
• Understand insurance options – Basic insurance is usually included, but consider upgrading to full coverage for peace of mind. Check if your travel insurance or credit card covers rental car insurance.
• Know the fuel policy – Most rentals use a full-to-full policy, meaning you return the car with a full tank. This is the most economical option, as pre-paid fuel packages often come with higher costs.
• Parking tips – Parking in the Cascais city center can be tricky, especially during summer. Look for designated parking lots or use free parking areas outside the main tourist zones to avoid high fees. Here’s more information on Cascais parking regulations.
• Toll roads and Via Verde system – Many Portuguese highways use an electronic toll system called Via Verde. Some rental companies provide a toll transponder, which makes driving more convenient. If your car doesn’t have one, you’ll need to prepay tolls online or at a post office. You can find more information on my Cascais driving guide. 
• Choose the right car type – If you plan to stay mainly in Cascais, a compact car is ideal for navigating narrow streets and parking. However, if you’re exploring the Sintra hills or remote beaches, an SUV or a larger car may offer better comfort and handling.

• Traffic rules and local driving habits – Portugal follows right-hand driving, and speed limits are strictly enforced. Be cautious at roundabouts, as local drivers can be aggressive when merging. Always have a GPS or offline maps handy.
• Check for hidden fees – Some rental companies charge extra for additional drivers, one-way drop-offs, or returning the car outside business hours. Read the terms carefully before confirming your booking.

Following these tips will ensure a stress-free car rental experience in Cascais, allowing you to enjoy your trip without unexpected surprises.

Best Road Trips from Cascais

Cascais and its surroundings offer a lot of scenic drives. Once you’ve got your rental car, here are some must-visit destinations:

Sintra (30-minute drive)

Sintra is one of my favorite day trips from Cascais. The winding roads take you through lush forests before revealing breathtaking palaces. Make sure to start early to avoid crowds at Pena Palace, explore the mystical gardens of Quinta da Regaleira, and climb the ancient Moorish Castle for panoramic views. Parking can be tricky, so be prepared to walk or use the shuttle services available.

Cabo da Roca (25-minute drive)

If you've ever wanted to stand at the edge of Europe, Cabo da Roca is the place to go. This rugged coastal viewpoint offers dramatic cliffs plunging into the Atlantic. The drive is spectacular, with scenic ocean views along the way. Be sure to bring a jacket—the wind here is no joke!

Guincho Beach (10-minute drive)

One of the best spots for a quick escape from the city, Guincho Beach is known for its wild beauty and fantastic surfing conditions. I love driving here just before sunset—the golden dunes and crashing waves create an unforgettable scene. If you're feeling adventurous, try a surf lesson or grab fresh seafood at one of the nearby beachside restaurants.

Conclusion

Renting a car in Cascais is the best way to explore beyond the town and experience Portugal’s stunning coastline and historic gems at your own pace. If you're planning a Cascais adventure, having a rental car gives you the freedom to travel on your own terms.
