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.

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.

You can no longer enter the grounds of this castle. You can see how nature has taken the castle back. We enjoyed our walk which had the castle on route. You can’t see much of the castle though.
