When planning our hiking adventures, whether trigbagging or not, there are a number of route planning resources that we tend to use. We wanted to share these with you to make it even easier for you to get outside and get trigbagging!

All the links and resources here are curated by us – we don’t accept payment or gifts for these links and we feel strongly that everything here is a useful tool. By all means, if you there’s something you use that is missing from this list – let us know! If we think it’s great, we will add it in.


Anyone you has delved even slightly into the world of trigbagging will have come across the incredible database that is trigpointing.uk. Thousands of trigbaggers across the UK use it to find trig points, log their bags and share information.

Bing Maps

When planning to bag a trig point, Bing Maps is our go to, NOT Google Maps! Why? Well, it’s because you can toggle Ordnance Survey maps, so you access accurate walking routes and trig point locations. We love to toggle between the OS map and a satellite map to help us get a really clear idea of where the trig point is. Forewarning, we have really struggled trying to get the OS map to work in the wild, so highly recommend the OS app as well (more on that later).

Click the ‘Road’ button in the top left corner to find the options for different map types.

Ordnance Survey App

Whilst we love a paper map, it’s really handy to have the OS maps app on your phone and well worth the premium subscription. In fact, I’d say it’s an essential for any serious walker.

The premium version puts their 1:25 and 1:50 maps at your fingertips, include augmented reality, GPS tracking (great if you’re a bit lost!), route planning, aerial imagery, and the ability to download maps for use offline.

Trig Pillar Map

Ok, we’ll admit it – the Trig Pillar Map is one of our tools. We created it because, other than the search function on the Trigpointing UK website, which is tempermental, we couldn’t find another source that maps all the UK trig pillar onto an actual map.

We’re constantly looking for ways to make it more useful, and welcome any feedback!


PlotARoute.com is our go to place for route planning – in fact the embedded routes at the end of a lot of our blog posts are from there. Whilst they sadly don’t have an Ordnance Survey overlay, it is incredibly easy to plot a route and gives you loads of info, such as expected completion time, elevation etc.

An alternative is the OS maps app – but it’s harder for us to share those route with you!


What3Words is an innovation sweeping the world. In fact, it’s used by emergency services to locate individuals much more accurately and easily than a street address.

What3Words divides the world into 3 meter squares and allocates each a completely unique, random, three word code. For example, the summit of Snowdon is super.ultra.enhancement.

We use it to pinpoint trig points (which can be notoriously hard to find in undergrowth) and make sure we’re meeting friends at the right places. We’ve started including the What3Words addresses of trig points in the info section at the top of our articles.


UKHillwalking and UKClimbing provide essential route resources, articles and information and competitions. Whilst most of our time is spent on UKClimbing checking out climbing routes, the hiking guides on UKHillwalking are also fantastic, and a must if you’re looking to tackle a particular challenge.

We used it extensively when planning our walks in North Wales, including the Snowdon Horseshoe.
