Adult admission ~£18–22; children under 5 free. Sits atop an extinct volcano — stroller-friendly ramp path requires effort on the climb. Best visited early morning (gates open 9:30am) to beat significant tourist crowds. Older kids love the Scottish Crown Jewels, the Stone of Destiny, and the firing of the One O’Clock Gun.
