Lock Eck loop via Benmore Botanic Gardens — Loch Lomond and The Trossachs National Park

Prepare for a demanding touring bicycle adventure on the Lock Eck loop, a difficult ride covering 23.5 miles (37.9 km) with a significant 2177 feet (664 metres) of elevation gain. This route typically takes around 3 hours and 39 minutes to complete. You will cycle through peaceful forests and along tranquil beaches on the western shore of Loch Eck, encountering a mix of wide forestry roads, steep slopes, and occasional loose material. A highlight is cycling through Benmore Botanic Gardens, where you can admire the majestic avenue of 160-year-old giant redwood trees. On clear days, the trail rewards you with panoramic views of Loch Eck and Beinn Mhor.

This demanding route is best suited for experienced and fit touring cyclists. Due to gravel sections and some unpaved segments, a robust bike is highly recommended; you might even need to push your bike on some difficult parts. The trail passes through remote forest terrain, offering a sense of escape into nature. Consider riding the loop clockwise, as one source suggests this might make the main climb easier. Benmore Botanic Gardens, a key point of interest, also features a cafe, making it a good spot for a break.

The Lock Eck loop is celebrated for its magnificent scenery, including Puck's Glen, Kilmun Arboretum, and Glenbranter Forest. Benmore Botanic Gardens is a world-class attraction along the route, renowned for its diverse plant collections and impressive architecture like the Golden Gates. Keep an eye out for local wildlife, such as red squirrels, sparrowhawks, and occasionally golden eagles, especially within the gardens. This challenging route offers a rewarding experience with stunning natural beauty and unique attractions.
