Edinburgh Castle

Scotland's most visited paid attraction sits on an extinct volcano overlooking the city. The medieval fortress houses the Crown Jewels, Stone of Destiny, and the National War Museum. The One O'Clock Gun fires daily except Sundays, a tradition dating to 1861. It sits in Edinburgh's Old Town, close to the other main sights. It ranks among Edinburgh's most visited sights, and for good reason - most itineraries include it on day one. Tickets cost £19.50 adult, £11.70 child, under 5s free and 2-3 hours is enough to see everything without rushing.

Priority: High - do not skip Time needed: 2-3 hours Best for: scotland's most important historic site with Skip if: You have limited mobility (steep climbs throughout) or find tourist crowds overwhelming Cost: £19.50 adult, £11.70 child, under 5s free

You walk cobbled courtyards between stone buildings that date back 900 years, climb narrow spiral staircases, and stand in rooms where Mary Queen of Scots gave birth. The views from the battlements show Edinburgh's layout clearly.

Accessibility: Wheelchair access to main areas via shuttle bus, but many buildings have steps

Scotland's most important historic site with genuine medieval architecture and royal regalia. That puts it near the top of any Edinburgh visit, and it deserves the spot. Combine it with Royal Mile and National Museum of Scotland - they are close enough to walk between and together make the strongest half-day in Edinburgh. Mornings are quieter if you want to take your time.

Skip if: You have limited mobility (steep climbs throughout) or find tourist crowds overwhelming
