9 Best Parks in Edinburgh | PlanetWare
"The Princess Street Gardens sit at the feet of Edinburgh Castle in the valley between the old city and the new city. Nor Loch once occupied the space, but the city began draining it in the 1770s, finishing in 1820. Wide paved paths lead throughout the park for full accessibility, roaming across fields of wildflowers, through wooded areas, and over streams and the railroad that divides the east and west sections of the park."
