Nice to look at from a distance, but rather a sad sight up close

Loch Lomond is the largest lake by surface area in Great Britain. There are great views across the loch from the trails around Balloch Castle Country Park. The country park is a 200-acre estate centred around the now ruinous castle. It's open to the public, with a series of waymarked walks available.

Below the castle (with limited opening hours) there is the Castle Park, which is open all day and offers beautiful views of the castle. There is also the bowling club with a clubhouse and outdoor area. Here too, it seems that it is permitted to spend the night in a camper van in the car park. The large shops (including Morrisons and Lidl, with many snack bars nearby) are only about a kilometer away on foot, and the city center is similarly close (directly behind them).

A small, pretty castle in the park. The building cannot be visited from the inside, but is very photogenic from the outside.

Newark Castle was for a long time hidden behind the giant cranes and sheds of the Clyde’s great shipyards. Only recently has it re-emerged to take its rightful place in the townscape of Port Glasgow. The land on which the castle is built was acquired by marriage in 1402 by a junior branch of the Maxwells, a powerful southern Scottish family. They remained its lords until 1694.

Dumbarton Castle is enthroned on the 73m high Dumbarton Rock. In its more than 1500-year history it was the scene of many feuds and skirmishes. Of great strategic importance in the Middle Ages, it always remained a suitable vantage point and place of refuge. David II hid here successfully in 1333-34 and Mary Queen of Scots in 1548 before they could flee to safer climes.

The original Balloch Castle was built in the 11th century and extensively re-built and improved in the 13th century. By the 19th century when John Buchanan bought the estate it was a ruin. He demolished what was left and built the current Tudor Gothic style castle. In 1915 Balloch Castle and the surrounding estate was bought by Glasgow City Council. It became a designated country park in 1980 and part of the Loch Lomond & the Trossachs National Park in 2002. Today the surrounding gardens, park land and wider estate are open to the public. There is a nice network of paths and trails that are great for a run. You can also extend a route up to nearby Knockour Hill.
