Wildlife Encounters

The Trossachs is a wildlife lover’s dream, offering opportunities to spot many of Scotland’s iconic species in their natural habitat. It’s the perfect destination for nature enthusiasts, and here are some species you might find:

Mammals

1. Red Deer: These are one of the most iconic species in the Trossachs, often seen grazing in the glens and on the slopes of the surrounding hills. They are the largest land mammals in the UK and a real symbol of the Scottish Highlands.
2. Fallow Deer: Another species of deer found in the park, with distinctive spotted coats. They can be spotted in the woodlands and glades.
3. Otters: Otters can be seen around the lochs and rivers of the Trossachs, often playing or hunting for fish in the water. Their playful nature makes them a delight to watch for those lucky enough to spot them.
4. Red Squirrels: Red squirrels are native to Scotland and can be spotted in the park’s woodlands, particularly in coniferous forests. While they face competition from grey squirrels, red squirrels still thrive and are often spotted in Callander, Balmaha, and from The Lodge at Aberfoyle. The Lodge offers a visitor centre, red squirrel feeders and a hide, allowing visitors a better chance to spot these cute creatures.
5. Pine Martens: These elusive animals are sometimes spotted in the forests of the Trossachs. Pine martens are members of the mustelid family and are known for their agility in climbing trees. They are mostly nocturnal, so spotting them is rare but possible.
6. Foxes and Badgers: Foxes roam the park’s woodlands, while badgers can be found in their setts, particularly at the edges of forests and farmlands. Both are nocturnal creatures but can be seen in the early evening during dusk.

Birds

The Trossachs is an exceptional birdwatching destination, with a wide variety of species, both resident and migratory.

1. Ospreys: These magnificent birds of prey are a highlight for many visitors to the Trossachs. Ospreys can often be seen near Loch Lomond or Loch Ard, hunting for fish. They usually return to the area during the summer months for breeding.
2. Golden Eagles: The more remote parts of the Trossachs, especially in the rugged mountain areas, are home to golden eagles. These powerful birds of prey are typically seen soaring high above the glens, though they are rarely spotted due to their elusive nature.
3. Hen Harriers: This graceful bird of prey can be seen in the moorland areas of the park, hunting for small mammals and birds. Hen harriers are known for their distinctive flight pattern, which looks like a “hovering” movement as they hunt.
4. Kestrels: These small falcons are common in the Trossachs and are often seen hovering in the air while hunting for small prey. Kestrels can be spotted on telephone wires or perched on trees.
5. Red Kites: Once nearly extinct in the UK, red kites have made a successful comeback and can be spotted in the Trossachs, particularly in the more open areas where they soar gracefully looking for carrion.
6. Dippers: These small, stocky birds can often be seen in the fast-moving rivers of the Trossachs, dipping below the surface in search of insects and small aquatic life.
7. Swans and Ducks: The lochs of the Trossachs are home to a variety of waterfowl, including mute swans, mallards, and other duck species. These can often be seen on the water or near the shore, particularly around Loch Lomond.
8. Peregrine Falcons: Known for their incredible speed and hunting prowess, peregrine falcons can occasionally be spotted on the cliffs and high vantage points of the Trossachs.
9. Woodpeckers: Both the great spotted woodpecker and the lesser spotted woodpecker are found in the woodlands of the park. Their drumming on trees is a distinctive sound to listen out for while walking through the forests.

Amphibians and Reptiles

1. Common Frog and Common Toad: These amphibians are common around the park’s water bodies, particularly in the spring and early summer when they breed in ponds and lochs.
2. Smooth Newts: Newts can be found in the shallow waters of the lochs and ponds, where they thrive in the wetter environments of the Trossachs.
3. Adder: Scotland’s only venomous snake, the adder, can be found in more remote and rocky areas of the park, particularly in the warmer, drier parts of the landscape. They are shy creatures and generally avoid human contact.
4. Grass Snakes: These non-venomous snakes are more commonly found in the woodlands and grassland areas of the park.

Insects

1. Midges: While not everyone’s favourite, midges are a notable part of the Trossachs’ ecosystem. These small biting insects are most active in the warmer months (spring to early autumn), especially near water sources.
2. Butterflies: The park is home to a range of butterfly species, some visible all year and others only in certain months.
3. Dragonflies and Damselflies: The lochs, rivers, and wetland areas attract several species of dragonflies and damselflies, which can be spotted hovering above the water during the warmer months.

Aquatic Life

There are around 20 species of fish in Loch Lomond, including the following:

1. Salmon and Trout: The lochs and rivers of the Trossachs are home to both salmon and various species of trout, making it a prime fishing destination. The River Teith, in particular, is known for its salmon runs.
2. Pike: These predatory fish can be found in the deeper waters of Loch Lomond and other nearby lochs. They are known for their aggressive hunting behaviour and are a popular catch for anglers.
3. Eels: European eels can be found in the waters of Loch Lomond and the River Forth. Although they are less commonly spotted, they are an important part of the local ecosystem.

5. Swimming in Loch Lomond: What to Know

There are several designated areas where swimming is encouraged, and these are typically located near the shorelines of popular spots like Balloch, Luss, and Balmaha. These areas tend to be safer, with easier access to the water and more shallow sections near the shore. Some beaches, like Luss Beach, offer a sandy area where swimmers can relax and wade into the loch.

Loch Lomond’s waters are typically quite cold, even in the summer, with temperatures usually hovering between 15°C to 18°C (59°F to 64°F). The colder temperatures can be a shock to the system, so it’s important to be prepared if you’re planning to swim! I learned this the hard way when I fell off my paddleboard unexpectedly! For those used to cold-water swimming, the loch provides a perfect challenge, but it’s recommended to wear a wetsuit, particularly if you plan to swim for an extended period.

Safety Considerations

While Loch Lomond is a great place to swim, it’s essential to keep a few safety tips in mind:

• Weather conditions: Be aware of the weather, as strong winds and sudden storms can make swimming dangerous. 
• Water currents: Loch Lomond is a large loch, and some parts may have stronger currents, particularly near the mouths of rivers or the loch’s deeper areas. It’s always advisable to swim in sheltered areas and avoid venturing too far out into the open water.
• Supervision: If you’re swimming with children or inexperienced swimmers, always ensure they are supervised at all times, as the water can be deceptively cold and deep.
• Wildlife: While the loch is home to various aquatic creatures, such as fish and otters, it’s generally safe to swim. However, it’s always a good idea to be aware of your surroundings and avoid swimming in areas where wildlife is particularly active.

Swimming Events

During the warmer months, Loch Lomond sometimes hosts open-water swimming events, where swimmers can take part in competitive races or simply enjoy the experience of swimming in the loch under more controlled conditions. These events are typically organised by local swim clubs or event organisers, and they offer a great way for both amateur and experienced swimmers to enjoy the loch safely. Go Swim Loch Lomond is taking place on 30th August 2025, with events ranging from a family-friendly 250m to a challenging 10km route for more experienced open-water swimmers.

Alternative Swimming Options

If you’re looking for a more controlled swimming experience, there are also outdoor swimming pools in the area. For example, McLaren Leisure Centre in Callander offers a heated outdoor pool with beautiful views of the surrounding hills, providing a comfortable and more predictable swimming environment. 

There are also a number spa resorts and lodges in the Trossachs area offering indoor swimming pools, hot tubs, and wellness facilities for a more luxurious swimming experience.

Loch Lomond Sauna

After a cold swim in the loch, why not warm up with a visit to the outdoor sauna? You can book a seat in a shared session or privately hire the entire sauna for you and your group. Sessions start at £15 for an hour, or £100 for private hire.

Visit Local Villages, Towns & Cities

The area is rich in culture and history, so it’s a great idea to visit the charming village of Luss or the bigger town of Callander, where you can stroll along quaint streets and discover local shops and cafes. 

If you want to travel a little outwith the park, you can immerse yourself in Scotland’s ancient past by exploring Stirling Castle, a historic site just a short drive away.

Loch Lomond Weather Conditions

The area has a similar climate to many surrounding parts of Scotland – mild summers, cool winters, and frequent rain! I recommend checking the Met Office’s forecast before your visit, although keep in mind it can change quickly!

As a general guide, here’s what to expect:

Spring (March – May)

• Temperatures: 5°C to 15°C (41°F to 59°F)
• Weather: Unpredictable, with a mix of sunshine, showers, and occasional frost early in the season.
• Best for: Spring flowers, fewer crowds, and increasing daylight hours.

Summer (June – August)

• Temperatures: 12°C to 20°C (54°F to 68°F) (though heatwaves can occasionally push it higher)
• Weather: Generally mild, but rain showers are common. Some sunny days can be quite warm.
• Best for: Hiking, Loch Lomond boat tours, and other water-based/outdoor activities, but midges (tiny biting insects) can be a nuisance, especially near water.

Autumn (September – November)

• Temperatures: 8°C to 15°C (46°F to 59°F)
• Weather: Can be quite wet, but also has beautiful autumn colours. Cooler temperatures start to set in by late October.
• Best for: Stunning foliage and quieter trails.

Winter (December – February)

• Temperatures: 0°C to 7°C (32°F to 45°F)
• Weather: Cold, with frost and occasional snow on higher ground, though lower areas mostly see rain.
• Best for: Peaceful landscapes, potential for snow-covered mountains, Northern Lights viewing (sometimes), and cosy stays in nearby lodges. Winter is also a great time to visit the area’s indoor attractions.

Overall, Loch Lomond is beautiful at any time of year but rain showers are common, so waterproof gear is always a good idea if you’re planning a hike.

The above conditions should be taken very loosely, as it’s not uncommon for spring or autumn to bring warmer days than summer. In fact, I’ve only ever been paddleboarding in Loch Lomond in September, and I didn’t need a wetsuit!
