Let’s calculate the fuel budget and mileage for a classic yet action-packed motorhome route through Turkey: Antalya — Pamukkale — Istanbul.

This route traverses the country from south to north, encompassing the coast, ancient ruins, mountains, and a major metropolis.

Calculation Parameters caravan turkey

For these estimates, we will assume a standard rental camper van (based on a Fiat Ducato or Peugeot Boxer):

Fuel consumption (Diesel): 10 liters per 100 km (accounting for air conditioning, luggage, and winding mountain roads).

Average price of diesel in 2025: 1.30 EUR per liter (approximately 130–135 Turkish Lira).

Toll roads: HGS system (automated toll collection).

1. Total Mileage and Travel Time

The route can be divided into two stages: the journey to Istanbul and exploring the city itself.

Route Segment    Distance (km)    Actual driving time (excluding stops)

Antalya → Pamukkale    ~240 km    3.5 – 4 hours

Pamukkale → Istanbul    ~620 km    7 – 8 hours

Local travel within Istanbul    ~150 km    —

TOTAL (approximate)    ~1,010 km    ~11–12 hours of driving

Recommended Itinerary:

Day 1: Antalya → Pamukkale (overnight stay near the travertines).

Day 2: Explore Pamukkale → head onto the O-31/E-87 toll highway toward Istanbul. Day 3: The long drive to Istanbul (approx. 600–650 km for the day).

Days 4–5: Istanbul (the motorhome stays parked; we travel around unencumbered).

2. Fuel Cost Estimate

Metric    Calculation    Amount (EUR)    Amount (TRY)

Total distance    1,010 km    —    —

Fuel consumption (10 L/100 km)    101 liters    —    —

Fuel cost    101 L × €1.30    ~€131    ~5,800 – 6,000 TRY

Important note: If you have an active driving style and your motorhome is fully loaded, anticipate a fuel consumption of 11–12 liters per 100 km. In that case, the budget will increase to €145–160.

3. Toll Road Costs (HGS)

Turkey has excellent toll motorways (*Otoyol*). They might seem intimidating at first—there are no toll booths or barriers, just cameras that scan a sticker on your windshield—but the system operates automatically.

Antalya – Burdur – Afyon section: The toll-free roads (D-300) are more scenic but slower. If you want to save time, opt for the toll sections.

Izmir/Aydin – Istanbul section (O-5/E-87): This is a modern motorway that runs through the mountains and crosses the Osmangazi Bridge (one of the longest in the world).

Estimated cost: For a distance of ~600 km on toll motorways, budget around €20–25. While the figure in Turkish Lira may look quite large (due to the exchange rate), it is a modest amount in Euros. A rental motorhome will typically already have an HGS (electronic toll collection) sticker affixed; toll charges will be deducted from a balance that you either top up yourself or that is settled against your security deposit.

4. Parking a motorhome in Istanbul

This is the most critical aspect in terms of both logistics and expenses. Navigating a 7-meter-long vehicle through the streets of Sultanahmet is both impossible and dangerous.

Scenario: You arrive on the outskirts of the city (for example, in the Halkalı or Beylikdüzü districts, or near the ferry terminal in Pendik).

Action: Leave the motorhome in a large, secure parking lot or at a caravan park (provided one is open on a weekday).

Costs: Parking costs 10–15 EUR per day. From there, you can continue your journey via metro or ferry. Budget 20–30 EUR for public transport for two people to explore the city.

Estimated total for the transit (for two people, excluding rental costs)

Expense Category    Amount (EUR)

Fuel (Diesel)    130–160 €

Tolls (HGS)    20–25 €

Parking in Istanbul (2 nights)    25–30 €

Food en route (cafés/groceries)    40–50 €

TOTAL for the journey:    ~215–265 €

Personal tip: The drive from Pamukkale to Istanbul is the most monotonous part of the trip. I recommend stopping for the night before reaching the city—perhaps in the area around Lake Sapanca or İzmit. These are beautiful, green areas with thermal springs, where it is far more pleasant and safer to spend the night in a motorhome than in a dusty parking lot on the approach to a metropolis of 15 million people.
