Royal Mile Edinburgh Guide: Top Attractions & Tips

The Royal Mile is the historic heart of Edinburgh, a mile-long stretch of cobblestones connecting Edinburgh Castle to the Palace of Holyroodhouse. It is packed with landmarks like St Giles' Cathedral, hidden underground 'closes,' and the Scottish Parliament, making it the essential starting point for any visitor to the Scottish capital.

For Australians and Kiwis making the long haul over to the UK, the Royal Mile is exactly what you imagine Scotland to be: moody, medieval, and steeped in more history than our two countries combined. But before you start snapping photos of the bagpipers outside St Giles, you need to make sure your phone is sorted. Don't get slugged by the Telstra International Day Pass or Optus roaming charges that can cost you a small fortune every day. Instead, grab an eSIM so you can land at Edinburgh Airport and have data the second you touch down.

Starting at the Top: Edinburgh Castle

You can’t miss it. Sitting on an extinct volcano called Castle Rock, Edinburgh Castle dominates the skyline. This is the starting point of the Royal Mile (the 'top' of the hill). It’s been a royal residence, a military garrison, and a prison. If you’re there at 1:00 PM, you’ll hear the One O'Clock Gun fire—a tradition that’s been going since 1861.

Inside, you’ll find the Honours of Scotland (the Crown Jewels) and the Stone of Destiny. Because the castle is massive and built of thick volcanic rock, mobile reception inside some of the deeper stone vaults can be spotty. However, once you’re out on the ramparts, you’ll get a cracking 5G signal from the local EE network, perfect for a quick FaceTime back home to show off the view over Princes Street Gardens.

The High Street and St Giles' Cathedral

As you walk down from the Castle, you enter the section known as the High Street. This is where the Royal Mile really comes alive. Look up and you’ll see the 'Crown Spire' of St Giles' Cathedral. It’s not technically a cathedral (it’s a High Kirk), but it’s been the religious heart of the city for 900 years. The interior is stunning, especially the Thistle Chapel with its intricate wood carvings.

Around this area, you’ll find heaps of street performers, especially if you’re visiting during the Festival Fringe in August. This is also where you’ll find the 'Heart of Midlothian'—a heart-shaped mosaic in the pavement. Watch your step; locals have a tradition of spitting on it for good luck. We wouldn't recommend it, but hey, when in Rome (or Edinburgh).

Exploring the Closes: The Real Mary King’s Close

The Royal Mile isn't just a straight line; it’s a spine with dozens of narrow alleys, or 'closes,' branching off it. These were once the site of towering tenement buildings where the city’s poorest lived. The most famous is The Real Mary King’s Close. It’s a warren of 17th-century streets that were actually built over and buried when the Royal Exchange was constructed.

Taking a tour down there is like stepping back in time to the plague years. It’s dark, creepy, and fascinating. Just a heads-up: because you’re literally underground, your AussieRoam data won't work down there—but that's probably for the best so you can focus on the ghost stories.

Connectivity: Why an eSIM Beats Roaming

When you’re navigating the winding wynds of the Old Town, you need reliable maps. Using your home SIM from Australia or New Zealand is a recipe for a massive bill. Telstra and Optus love to charge a daily fee just for the privilege of using your own data.

With AussieRoam, you're using local UK infrastructure. In Edinburgh, that means you're tapping into EE or 3 (Three). EE is widely considered the top dog for coverage in the UK, especially for 5G in cities. If you head out to the Highlands after Edinburgh, having access to these local networks is the difference between having a signal and being stranded.

You can see plans for the UK that cover everything from a quick week in the city to a month-long road trip.

The Canongate and the Scottish Parliament

The lower half of the Royal Mile is called the Canongate. It’s generally quieter than the top half but no less interesting. Stop by the Museum of Edinburgh (it’s free!) to see the collar and bowl of Greyfriars Bobby, the loyal dog who famously guarded his master's grave for 14 years.

At the very bottom, the architecture takes a sharp turn into the 21st century with the Scottish Parliament Building. It’s a controversial design—some love the modern abstract shapes, others reckon it looks like a pile of sticks—but it’s worth a look. Directly across from it is the Palace of Holyroodhouse, the King’s official residence in Edinburgh. If the Royal Standard flag is flying, he’s home.

Data Needs for Your Edinburgh Trip

How much data do you actually need for a day on the Royal Mile?

• Google Maps: Essential for finding those hidden pubs.
• Social Media: Uploading high-res photos of the Castle and Parliament.
• Research: Looking up the history of the Covenanters or finding the best Sunday roast in London for your next stop.
• Communication: Using WhatsApp to coordinate with your travel mates.

We recommend at least a 3GB or 5GB plan for a week-long stay. If you’re a heavy user or working remotely while you travel, the 20GB or 50GB options are a safer bet. You can always top up if you run low. Before you buy, make sure your phone is compatible with eSIM technology; most iPhones and Samsungs from the last few years are good to go.

Arrival and Setup at the Airport

The best way to handle your connectivity is to be prepared. We suggest buying your eSIM while you're still at the airport in Sydney, Melbourne, or Auckland. You can scan the QR code and get the profile installed while you're waiting for your flight.

Once you land at Edinburgh Airport (EDI), simply go into your phone settings and switch your mobile data to the eSIM. Make sure 'Data Roaming' is turned on for the eSIM profile—this allows it to connect to the local EE or 3 networks. You'll be able to book an Uber or check the bus times for the Airlink 100 into the city center before you've even left the terminal. If you need a hand, our guide on how the setup process works covers both iPhone and Android in detail.

Beyond Edinburgh

If your UK trip is part of a larger global adventure, perhaps heading to Japan or Thailand next, remember that an eSIM is the most flexible way to stay connected. Whether you're comparing Shinjuku vs Shibuya in Tokyo or hiking the Arthur's Seat volcano right next to the Royal Mile, having instant data makes the experience much smoother.

For those staying in the UK for a while, you can see plans that last up to 180 days, which is perfect for expats or long-term travelers.

The bottom line

Walking the Royal Mile is a non-negotiable Edinburgh experience. From the heights of the Castle to the modern Parliament, it’s a journey through Scotland's timeline. To make the most of it, skip the overpriced roaming from back home and stick with a local eSIM. You’ll save money for more important things—like another round of Scotch whisky at a pub in the Grassmarket.
