Iceland and Greenland sit next to each other on the map, share a Viking history, and both get labeled "Arctic," which is exactly why people mix them up when planning a trip. But for most travellers, especially anyone planning a self-drive holiday, the two islands offer very different experiences.
Quick answer
For most leisure travellers, especially those who want to drive themselves around, see a mix of landscapes in one trip, and keep costs and logistics predictable, Iceland is the more practical choice. It has a road network connecting the whole country, year-round international flights into Keflavík, and infrastructure, hotels, fuel stations, supermarkets, spread across the island. Greenland is genuinely spectacular but suits travellers with more flexible time, higher budgets, and an appetite for boat- and flight-based expedition travel rather than a self-drive itinerary.

Is Greenland colder than Iceland?
Yes, Greenland is colder than Iceland overall. Iceland sits in the path of the Gulf Stream, which keeps its coastal temperatures milder than its latitude would suggest, winters are cold but generally manageable, and summers are cool and comfortable. Greenland's climate is dominated by its enormous ice sheet, which covers most of the interior and keeps temperatures low even in summer, particularly away from the coast.
So while Iceland is not colder than Greenland, it's also not "warm" in the way some travellers expect, it's simply more temperate and more predictable across the seasons. If you're planning a winter trip to Iceland specifically, it's worth reading up on what changes on the roads once the weather turns; the driving in Iceland in winter guide covers what to expect month by month.
One small but telling detail: Greenland has mosquitoes in summer, while Iceland famously does not.
How different are the two islands, really?
Greenland is the largest island in the world and is covered almost entirely by a permanent ice sheet, with glaciers spilling down to the coast in dramatic fjords. Iceland is a large island in its own right, but its glaciers, including Vatnajökull and Snæfellsjökull, are smaller and, importantly, far easier to get close to. In Iceland, glaciers are something you can build into a day's driving. In Greenland, they define the entire landscape and are often only reachable with a guide, boat, or flight.
The saying "Iceland is green, Greenland is ice" isn't perfectly accurate, but it captures something real: Iceland's terrain shifts constantly between lava fields, moss, waterfalls, black sand beaches, volcanoes, and hot springs, often within a single day's drive. Greenland's scenery is more singular in character, vast, icy, and remote, which is part of its appeal, but it changes how you experience it as a visitor.
Population and infrastructure
Iceland has a population of close to 400,000, while Greenland's is closer to 55,000. That gap shows up immediately once you're on the ground. In Iceland, towns and services are distributed around the entire island, you'll find fuel stations, supermarkets, cafés, and emergency services even in fairly remote regions. In Greenland, settlements are small and scattered mostly along the south and west coasts, and large parts of the country are uninhabited and effectively unreachable without specialised transport.
For a self-drive traveller, this matters practically: in Iceland you can generally plan a route knowing services will be available along the way, whereas in Greenland that assumption doesn't hold, because there isn't a road network to plan a route on in the first place.
Getting there and getting around
This is where the two destinations diverge most sharply for anyone weighing "Greenland or Iceland for vacation."
In Iceland, Keflavík International Airport has daily, year-round flights from North America, Europe, and beyond. Once you land, you can pick up a rental car and be on the road within minutes, Blue Car Rental's online check-in and key-box pickup (for customers who add the Liability Waiver and complete online check-in) at Keflavík are built specifically for that kind of arrival, whether you land early in the morning or late at night. From there, the country has a modern road system, including the Ring Road (Route 1) that circles the island, giving you access to waterfalls, volcanoes, glaciers, black sand beaches, and hot springs on your own schedule. In summer, a properly equipped 4x4 can also reach the highland F-roads, opening up some of the most remote parts of the country; the F-roads highlands guide explains what that involves and when those routes are typically open.
In Greenland, there are no roads connecting towns and villages, so self-drive travel between them simply isn't an option. Movement between destinations happens by boat, small aircraft, or occasionally helicopter. That makes travel slower, more weather-dependent, and generally more expensive, a short distance on the map can take hours, or a full day, to cover. Greenland opened its first true international airport in Nuuk in recent years, but access is still limited, particularly in winter, and most international arrivals still route through Iceland or Denmark on smaller planes.
If your idea of a good trip involves stopping when something catches your eye rather than following a fixed schedule dictated by flight or boat availability, that difference alone tends to settle the question.
Culture: Nordic roots, different paths
Iceland and Greenland share a Viking history, Erik the Red settled Greenland after being exiled from Iceland, and his son Leif Erikson later sailed from there to reach North America centuries before Columbus. But the two cultures developed differently. Iceland is closely tied to the wider Nordic and European world, with a modern culture still rooted in Viking-era literature and a strong relationship with its landscape. Greenland has a strong Indigenous culture, particularly in smaller villages, while larger towns like Nuuk carry more Danish influence, Greenland remains part of the Kingdom of Denmark and is geographically considered part of North America.

Which country fits your trip better?
The honest answer depends on what kind of traveller you are, but for most people planning a first Arctic trip, budgeting normally, and wanting to see a lot in a limited number of days, Iceland is the more practical fit. You get dramatic, varied landscapes, easy year-round access via Keflavík, and a road network that lets you build your own itinerary rather than working around boat and flight schedules.

Greenland rewards travellers with more flexible time, a higher travel budget, and a preference for expedition-style trips, think fjord cruises, guided glacier hikes, and small-plane hops between remote settlements, over a self-drive holiday.

If Iceland is the choice, vehicle selection matters. A compact 2WD is often fine for a summer Ring Road trip on paved routes, while winter travel, gravel roads, or highland detours usually call for something with more capability; the 4x4 questions to ask yourself guide walks through how to decide, and the full range of vehicles, from small cars to SUVs and larger 4x4s, gives you a sense of what's realistically available for different routes and seasons.

Every rental includes CDW, SCDW, Gravel Protection, Theft Protection, and Third-Party Liability as standard, and travellers who want broader protection against gravel chips, sand and ash, or water damage on legal crossings can look at the insurance options before deciding what level of cover fits the trip. Rather than a deposit that ties up funds, Blue Car Rental takes a credit-card imprint as security, so nothing is held or blocked during the rental period.
