Frequently Asked Questions

Is the Lagan Towpath and Divis Mountain Loop suitable for touring bicycles?

The suitability of this route for touring bicycles depends heavily on the section. The Lagan Towpath is largely paved and flat, making it ideal for touring cyclists of all skill levels. However, the Divis Mountain section presents a significantly more demanding experience. It features substantial elevation gain, unpaved, gravel, and natural singletrack sections that are more suited for mountain bikes or robust hybrid bikes with appropriate gearing and tire clearance. Touring cyclists may find parts of Divis Mountain challenging and might need to dismount and push their bikes.

Where can I park to access the route?

For the Lagan Towpath section, you can find parking at various points along its length, including in Lisburn or Belfast, near parks like Ormeau Park or Lady Dixon Park. For the Divis Mountain section, there is typically parking available at the National Trust car park at the base of Divis and the Black Mountain, which provides direct access to the mountain trails.

Are there any permits or entrance fees required for this route?

Generally, there are no specific permits or entrance fees required to cycle the Lagan Towpath or the trails on Divis and the Black Mountain. The Lagan Valley Regional Park, which encompasses much of the towpath, is freely accessible. Divis Mountain is managed by the National Trust, and while access to the trails is usually free, car park charges may apply at certain times or locations.

Is the route dog-friendly?

Yes, both the Lagan Towpath and the trails on Divis and the Black Mountain are generally dog-friendly. However, dogs must be kept on a lead, especially on the shared-use towpath to ensure safety for all users, and on Divis Mountain due to livestock and ground-nesting birds. Always remember to clean up after your dog.

What is the best time of year to cycle this route?

The best time to cycle this route is typically during the spring, summer, and early autumn months (April to October). During these periods, you'll generally experience milder weather, longer daylight hours, and better trail conditions. The Lagan Towpath is accessible year-round, but the exposed nature of Divis and the Black Mountain means it can be very windy and wet in winter, making cycling more challenging.

What can I see along the route?

Along the Lagan Towpath, you'll enjoy tranquil riverside views, passing through various parks like Ormeau Park, Lady Dixon Park, and Belvoir Park Forest. You'll also see historic canal features and varied birdlife. The Divis and the Black Mountain section offers spectacular panoramic views over Belfast, Lough Neagh, the Mourne Mountains, and Strangford Lough from its summit, along with open heath and blanket bog landscapes.

Are there amenities like cafes or toilets along the way?

Yes, along the Lagan Towpath, you'll find various refreshment stops and public toilets, particularly in the parks and towns it passes through. On Divis and the Black Mountain, amenities are more limited, but there is typically a visitor centre or cafe at the main car park, offering facilities.

Does the route intersect other well-known paths?

Yes, the route incorporates significant sections of the Lagan Towpath, which is part of the National Cycle Network Route 9. It also intersects with parts of the EuroVelo 1 - Atlantic Coast Route - part Northern Ireland.

What is the terrain like on the Lagan Towpath and Divis Mountain Loop?

The terrain is highly varied. The Lagan Towpath is predominantly flat, well-maintained, and mostly asphalt, making for easy cycling. In contrast, the Divis and the Black Mountain section features significant climbs, with surfaces ranging from paved to unpaved, gravel, natural trails, and singletrack. These mountain sections can be rough and challenging, especially after rain.

Is this route suitable for families with children?

The Lagan Towpath section is highly suitable for families and beginners due to its flat, traffic-free, and mostly paved surface. However, the Divis and the Black Mountain section is considerably more challenging with steep climbs and rough terrain, making it generally unsuitable for younger children or those on standard family touring bikes. Families might consider cycling only the towpath section or exploring specific, easier trails on Divis Mountain separately.

What kind of bike is recommended for this loop?

Given the contrasting terrain, a hybrid bike with good tire clearance and a wide range of gears would be a good compromise if you plan to tackle the entire loop. For the Lagan Towpath alone, any touring or road bike is suitable. For the Divis and the Black Mountain section, a mountain bike is strongly recommended due to the steep climbs, descents, and varied, often rough, surfaces.
