Outside of Scotland these Lochs are known as Lakes, Glens as Valleys. Also Ben or Beinn, is a term given to mountains up to a certain height, but those over 3000 feet(914.4 metres) are called a Munro.
The region of Perthshire Scottish Highlands extends from Loch Lomond in the west, to the earldom of Gowrie in the east. The Trossachs is called ‘Rob Roy McGregor‘ country. Rob Roy is a Local Hero in some historians eyes and a villain in others as he roamed the Perthshire Scottish Highlands countryside as a cattle rustler. He was a kind of Scottish Highlands Robin Hood taking from the rich and giving to the poor. He is buried in the small village of Balquhidder.
Basically, yes - except when it is a fjord. Scotland has over 31,000 freshwater lochs in Scotland, though only around 350 of any substantial size. The country is also fringed with sea lochs, or fjords. The vast majority of both are in the north and west of the country, but you need not travel far in any direction in Scotland to come up against a picturesque stretch of water. Much more difficult is learning the pronunciation. Say "lock" to a local and you may as well just shuffle off home now. Scots pronounce the "ch" as in "Bach", and will treat you with more respect if you do, too. If you're having trouble with the accent, there is some exceptions. Scotland also has two lakes, Menteith in the Trossachs and Superior in Galloway. Perthshire has many great Lochs and Glens. You will see fabulous views of Highland Perthshire hills and mountains (known as Bens) glistening in the crystal clear Lochs.
In Scotland, a glen is a valley with a stream or river running through it. It is generally narrower than a strath. The word comes from the Gaelic wordgleann, while strath is derived from the Gaelicsrath, a broad valley.There are many beautiful glens and straths in Scotland. Below is a selection of the more well known glens in the Perthshire Scottish highlands. Lochs and Glens.
Angus Glens - Glenisla, Glenprosen and Glenclova.
Many “Munros” are within this area. Including, Ben Lawers, Beinn Ghlas, Ben Chonzie, Schiehallion.
Glenshee Ski area car park 2000 feet above sea level, only 40 minutes from Alyth, Blairgowrie offers splendid hill walking with easy access to several “Munros,” Including Carn Aosda Glas Maol Cairnwell, Carn an Tuirc.
All these Lochs and Glens make up the splendour of the Perthshire Scottish Highlands
Ben Lawers - Height: 1214m/3982ft Grid Ref: NN63554142
Ben Lawers is the highest mountain in the Southern Highlands and one of Scotland's most popular peaks. It is the tenth highest mountain in Scotland and forms part of seven Munros, or peaks above 3,000ft. High above Loch Tay, it is also known for its rare Alpine flora and for its birds, which include ring ouzels, dippers and ptarmigan. Ii was bought by the Trust's Mountain Country Fund, founded by Percy Unna, in 1950 and was declared a National Nature Reserve in 1975.
Beinn Ghlas - Height: 1103m/3618ft Grid Ref: NN62544047
Beinn Ghlas is an easy mountain to climb with slopes primarily of grass with some rocky outcrops, although the northern slopes are craggy and should be avoided. Due to its proximity to The National Trust Visitor Centre and Nature Trail, Beinn Ghlas is also one of Britain's most frequently climbed mountains, as testified by the broad eroded path up its SW ridge. There is an alternative descent from the col between Ben Lawers and Beinn Ghlas on the N slopes of Beinn Ghlas which leads to the bealach at the head of Coire Odhar then on an old drove road to join the original path down the Nature Trail to the car park.
Ben Chonzie - Height: 931m/3054ft Grid Ref: NN773308
Ben Chonzie is the highest point of the heathery moorlands to the north of Crieff. Its finest side is to the east above Glen Turret, but it is more frequently and quickly climbed using tracks from the west.
Schiehallion - Height: 1083m/3553ft Grid Ref: NN7139548
Schiehallion is one of the most familiar and best known mountains in Scotland. A whaleback ridge from most viewpoints, it appears as a perfect cone when seen from across Loch Rannoch. Contour lines were invented on the mountain as part of an experiment to determine the mass of the earth.
Beinn Dearg - Height: 1008m/3307ft Grid Ref: NN852777
Beinn Dearg is a somewhat shy Munro, laying deep within the wild country eastwards of Drumochter. The best access is from Blair Atholl, from where it's a ten mile walk to the top with tracks and paths all the way. The actual ascent path is one of the most benign and easily graded in the district. The massive, stony summit carries a wind shelter (pictured). No roads, towns or villages can be seen from the top, just a magnificent 360-degree panorama of mountains in which the Cairngorms, the Mounth, the Glen Tilt hills, the Drumochter hills and the Ben Lawers group are all prominent.
Ben Vorlich - Height: 985m/3231ft Grid Ref: NN62911892
Ben Vorlich above Loch Earn is one of the best-known Scottish mountains and is very popular. Close to the Highland boundary, it gives excellent views into the Lowlands.
Stuc a'Chroin - Height: 975m/3918ft Grid Ref: NN61741746
Stuc a'Chroin is a steep and rocky peak, involving a scramble when ascended (as is common) from neighbouring Ben Vorlich.
Braigh Coire Chruinn-bhalgain - Height: 1070m/3510ft Grid Ref: NN925724
One of the Beinn a'Ghlo group, Braigh Coire Chruinn-bhalgain is best ascended by first climbing Carn Liath (q.v.) and then following the ridge. There's a good path all the way though there is quite a substantial drop between the two summits. The view is dominated by Beinn a'Ghlo's principal top, Carn nan Gabhar, and its outlier, Airgiod Bheinn, filling the eastern arc. The Cairngorms are well displayed to the north, and the main feature eastwards is the Ben Lawers massif. A really fine climb.
Meall Greigh - Height: 1001m/3284ft Grid Ref: NN67404382
The easternmost of the Lawers range, Meall Greigh is fairly shapeless and sprawling, usually traversed en-route to Meall Garbh. With no higher peaks through the eastern ark it does enjoy extensive views.
Meall nan Tarmachan - Height: 1044m/3425ft Grid Ref: NN58513902
Meall nan Tarmachan is the only Munro summit on the Tarmachan ridge. It can be climbed quickly from Lochain na Lairige but is usually enjoyed as part of a very enjoyable and rocky scramble along the whole ridge. The ridge is very prominent from Killin.
Ben Vrackie - Height: 841m/2759ft Grid Ref: NN95076324
Ben Vrackie is one of the most accessible mountains(Corbett) in this corner of the Highlands, situated within three miles of the town of Pitlochry. There is a good path all the way, initially along residential roads and then a farm driveway and a woodland path. The view from the summit is excellent, encompassing the Ben Lawers group, Schiehallion, the Glen Tilt hills, the Mounth and the Ochils. The name is possibly a corruption of Beinn Bhreac ("speckled mountain").
Auchnafree Hill - Height: 789m/2589ft Grid Ref: NN808308
Auchnafree Hill is the highest of the sprawling moorlands on the east side of Loch Turrett.
Choinneachain Hill - Height: 787m/2582ft Grid Ref: NN818289
Just a few metres lower than its parent, Auchnafree Hill, this top is most easily reached along the track up from the Loch Turrett dam. A sketchy path leads north from King Kenneth's Cairn, from which you venture off left to reach the summit. Ben Chonzie and Auchnafree Hill shut in the view somewhat, but the Ben Lawers range is prominent to the northwest and there is a suggestion of a huge plateau to the northeast that might be the Cairngorms.
Torlum - Height: 393m/1289ft Grid Ref: NN819192
Torlum is a minor summit situated a few miles west of Crieff in Perthshire. The lower slopes are wooded, the upper slopes heathery. The easiest access is by a forest path from the vicinity of Ballochargie to the east; there is a path up to the summit dome but peversely it is more easily found on the descent. The Strathearn towns of Comrie and Crieff are well seen, while the Ochils occupy the southern arc of the view and Ben Chonzie and its neighbours tower over the scene to the north.
This is a small review of some of the more famous Lochs and Glens in the Perthshire Scottish Highlands.
