Renting a car in Costa Rica looks cheap online. Then you reach the counter. The difference is almost always the same handful of fees: mandatory insurance, collision cover, a big card hold, airport charges and tax. Here's what each one really costs for 2026-27, how to spot it in a quote, and whether you need a car at all for a La Fortuna trip.
Why a $15-a-day quote becomes $100
Most booking sites show a base rate with no insurance. In Costa Rica that number is close to meaningless, because one insurance is required by law and another is effectively required unless you bring proof of your own.
What usually isn't in the headline price:
- Mandatory third-party liability (TPL/SLI)
- Collision damage waiver (CDW), unless you decline it with a letter
- Airport concession fee (about 13% at SJO, 13.75% at LIR)
- 13% VAT
- Small daily plate and environmental fees (about $2/day)
- Extras: additional driver, child seats, young-driver fee (under 25)
Rule of thumb: compare the all-in total for your exact dates, never the daily base rate.
Mandatory insurance (TPL/SLI): the fee you can't skip
Third-party liability covers injury or damage you cause to other people and their property. It's government-mandated on every rental, and no credit card, travel policy or home auto insurance replaces it. Agencies call it TPL, SLI, PLI or "liability protection", but it's all the same thing.
Expect roughly $13-21 per day, depending on the agency and car class. On a 7-day rental, that's about $90-150 that wasn't in the online quote.
CDW: the one you can (sometimes) decline
The collision damage waiver covers the rental car itself. Agencies must offer it, but most accept credit-card coverage instead, if you bring proof:
- Call your card issuer and ask for a letter of coverage for Costa Rica.
- It must show your name, the card's last four digits and that coverage applies in Costa Rica. Some agencies also want the rental dates.
- Pay for the rental and the deposit with that same card.
The trade-off: decline CDW and the agency's hold usually jumps to $1,000-3,000. If anything happens, you pay first and claim it back from your card company later. Buying the agency's CDW instead costs about $10-37/day (basic vs. full) and shrinks the hold, sometimes to a few hundred dollars.
Neither choice is wrong. Using the card saves money if you have enough credit limit. Buying full cover saves hassle.
Deposits: why your card limit matters
The hold isn't a charge, but it ties up your credit for the whole trip and takes days to release after you return the car. Typical patterns:
- Full agency coverage: about $100-750
- TPL + basic CDW: about $750-1,500
- TPL only (declined CDW with a card letter): about $1,000-3,000
Most agencies require a credit card in the main driver's name for the hold. Debit cards are often refused or need prior approval. Bring a second card for everything else.
Airport fees and tax
Picking up at the terminal is convenient, but on-airport desks add a concession fee of about 13% at SJO and 13.75% at LIR. Many reputable agencies are just off-airport and run a free shuttle, which avoids that fee entirely. Add 13% VAT on the rental, and ask whether the quote already includes both.
A realistic all-in example (7 days, compact SUV, high season)
| What you pay | Per day | 7 days |
|---|---|---|
| Base rate | $50 | $350 |
| Mandatory liability insurance (TPL) | $16 | $112 |
| Basic collision cover (CDW) | $15 | $105 |
| Taxes & fees (VAT, airport) | — | $90–150 |
| Total, all-in | ~$100 | $660–720 |
High-season quotes typically run $90–130/day all-in. Expect a card hold of about $750–1,500 on top.
Gas is extra. Prices are regulated nationally: regular was ₡719/L (about US$1.60/L, $6/gal) from October 2026.

Driving to La Fortuna
- From SJO (San José airport): about 2.5-3 hours via Ciudad Quesada. The roads are paved but winding through the mountains, and the Central Valley has heavy traffic. Leave early.
- From LIR (Liberia airport): about 2.5-3 hours via Cañas and Tilarán or via Upala/Bijagua. Also paved.
- Use Waze. It's the local standard and handles road closures well. Get an eSIM or local SIM before you leave the airport.
- Avoid driving at night if you can. Roads are dark and unlit, with pedestrians and animals. In January it's dark by about 6-6:15 PM (more in our January guide).
Do you need a 4x4? For La Fortuna, usually not. The main roads, the town and the big attractions are all paved. A 4x4 or high-clearance SUV only matters for some hilltop lodges and gravel back roads. Expect narrow one-lane bridges like this one, too. Our 4x4 guide goes deeper.
Parking, theft and gas stations

- Never leave anything visible in the car. That matters most at trailheads and the free hot-river pull-offs, which are known for break-ins. Take valuables with you or leave them at the hotel.
- Use paid or guarded parking at the waterfall, the national park and in town (parking at the waterfall is included in the ticket).
- Gas stations are full-service. Say "lleno, regular, por favor" for a full tank of regular. Cards are widely accepted. Price is the same everywhere.

Do you even need a car for La Fortuna?
Honestly, often not. If you're staying in or near town:
- Shared shuttles run from both SJO and LIR, roughly $55-70 per person.
- All of our La Fortuna tours can include hotel pickup, from the morning Arenal Volcano hike to the rest of the lineup.
- Taxis cover the short hops: the waterfall is about 10 minutes from town.
A car is worth it if you want early starts on your own schedule, the free hot river after dark, or day trips like Río Celeste. For a family of four, a car can also work out cheaper than shuttles.
Before you pay: the checklist
Ask the agency, in writing:
- The all-in total for your dates, including TPL, CDW (if you're taking it), VAT and any airport fee
- The exact card hold, with and without their CDW
- Whether they accept your credit-card CDW letter
- The young-driver and additional-driver fees
- The fuel policy and what happens if you return early or late

Common questions
Is insurance mandatory when renting a car in Costa Rica?+
Yes. Third-party liability (TPL, also called SLI) is required by law on every rental and can't be replaced by credit-card or home insurance. Collision cover (CDW) is the part you can sometimes decline.
Can I use my credit card's rental insurance in Costa Rica?+
Only for CDW, and only with a letter from your card issuer confirming coverage in Costa Rica, your name and the card's last four digits. Expect a larger hold, roughly $1,000-3,000.
How much is the deposit on a Costa Rica rental car?+
It depends on the coverage you buy. With full coverage from the agency it can be a few hundred dollars. With TPL only (declining CDW), $1,000-3,000 is common.
Do I need a 4x4 for La Fortuna?+
No. The roads from SJO and LIR and around town are paved. A 4x4 helps only for some hilltop lodges and gravel back roads.
How long is the drive from San José airport to La Fortuna?+
About 2.5-3 hours. From Liberia airport, about 2.5-3 hours.
Do I need a car in La Fortuna?+
Not necessarily. Shared shuttles run from both airports, and all of our La Fortuna tours can include hotel pickup. A car mainly adds flexibility for the free hot river and early starts.
