Arthurs Seat – Complete Guide to Edinburgh’s Ancient Volcano

Rising 251 metres above the streets of Edinburgh, Arthur’s Seat is the centrepiece of Holyrood Park and the remains of an ancient volcano. This guide covers the walking routes, history, geology, and practical advice for anyone planning to visit the summit.

Arthur’s Seat is part of a group of hills that includes Salisbury Crags. The entire area has been designated a Site of Special Scientific Interest (SSSI) due to its geological and ecological value. Whether you are a hiker, a photographer, or a history enthusiast, the hill offers something for everyone.

The summit provides panoramic views of Edinburgh’s skyline, the Firth of Forth, and the Pentland Hills. With multiple routes of varying difficulty, the walk is accessible to most fitness levels. Below is a quick overview of the key facts.

Why Is It Called Arthur’s Seat?

Key Insights

• Arthur’s Seat is not just a hill but the remains of a volcano that erupted over 340 million years ago.
• Despite its name, there is no definitive historical evidence linking it directly to King Arthur; the name likely originated from later medieval legend or a corruption of ‘Ard-na-Said’ (Gaelic for ‘height of the arrows’).

Snapshot Facts

The name “Arthur’s Seat” has been a subject of debate for centuries. Wikipedia notes that the earliest recorded reference dates to around 1360. Theories about the origin include a corruption of the Gaelic “Ard-na-Said” (height of the arrows), a connection to the legendary King Arthur, or even a local chieftain named Arthur. No direct archaeological evidence links the hill to the mythic king, so the mystery remains open.

How Tall Is Arthur’s Seat and Is It a Volcano?

Arthur’s Seat stands 251 metres (823 feet) above sea level, making it the highest point in Holyrood Park. Geologically, it is an extinct volcano that last erupted during the Carboniferous period, around 340 million years ago. The visible remains include two distinct vents known as the Lion’s Head and the Lion’s Haunch.

Historic Environment Scotland describes Holyrood Park as dominated by this ancient volcanic site. The hill’s core is a volcanic plug – magma that solidified within the volcano’s vent. Softer surrounding rock eroded over millions of years, leaving the resistant core we see today.

Formation and Landscape

Glacial activity during the Ice Ages shaped the landscape further, exposing the volcanic neck and carving the surrounding crags. The result is a distinctive skyline visible from most of Edinburgh. Salisbury Crags, the prominent basalt cliffs to the west, are part of the same volcanic system.

What Are the Best Walking Routes to the Summit?

There are four main colour-coded routes to the summit, each offering a different experience. The Walkhighlands guide provides detailed descriptions and maps. Here is a summary of the main options:

• Red Route (Moderate) – Follows an ancient lava flow from the Royal Mile near Holyrood Palace. Starts at Broad Pavement.
• Blue Route (Gentle) – Passes through Hunter’s Bog and joins the Red Route near Salisbury Crags. A more gradual ascent.
• Green Route (Easy) – A shorter path crossing grassy slopes and ancient terraces. Ideal for beginners.
• Purple Route (Steeper) – A direct ascent from Holyrood Park Road near Pollock Halls. Challenging but quick.

A popular circular walk starts and ends at the Scottish Parliament, passing St Margaret’s Loch and the ruins of St Anthony’s Chapel (14th century). For those wanting an easier option, driving to Queen’s Drive parking near St Margaret’s Loch provides a short path to the summit.

Difficulty and Duration

The walk is rated Easy to Moderate. Most people take between 30 minutes and 1 hour to reach the summit from the base. Allow about 2 hours total if you plan to stop for photos, a picnic, or to explore side paths. The AllTrails page includes user reviews and up-to-date trail conditions.

What Is the History of Arthur’s Seat?

The area has been inhabited for thousands of years. During the Iron Age (around 2,000 years ago), a hill fort was built on the summit and slopes. Evidence of ancient settlements can still be seen in the form of terraces and earthworks.

In the medieval period, Holyrood Park was established as a royal hunting ground. The hill appears in literature as early as 1360. By the 19th century, Arthur’s Seat had become a popular destination for Romantic poets and writers. Robert Louis Stevenson wrote about the hill in his book “Edinburgh: Picturesque Notes” (1879), describing it as “a hill for magnitude, a mountain in virtue of its bold design.”

The hill is also mentioned in Mary Shelley’s “Frankenstein.” Local folklore includes tales of King Arthur and a sleeping dragon. One May Day tradition involved maidens washing their faces in the morning dew on the hill for good luck.
