8) What are the natural wonders of Loch Lomond and the Trossachs

We've mentioned the Munros; there are smaller Corbetts and some excellent hill to climb, lochs and islands. In addition, there are some beautiful glens, waterfalls and forests. Both the Argyll Forest in Cowal and Queen Elizabeth forest in the Trossachs are spectacular.

The Great Trossachs Forest is the size of Glasgow, a 200-year project to protect the land and animals. Finally, the Highland Boundary Fault, which runs across Scotland, divides the Scottish lowlands with Highlands cuts through the National Park and is most noticeable close to Balmaha.

9) What wildlife is in the National Park?

The number of Red Squirrels in the National Park has grown in recent years. View them from wildlife hides in several places, including Aberfoyle, Cormonachan Woodlands, Loch Goil, Ardentinny Benmore Botanic Garden, and Glenbrater; there is also a Red Squirrel trail in Balmaha. 

You'll see Highland Cattle in fields, plus, if you're lucky, Roe Deer and Red Deer. 

There are two RSPB reserves at Gartocharn and Inversnaid; look out for Ospreys and Golden Eagles. On the seawater lochs at Cowal, you can see Otter, Harbour Porpoise and Common seal.
