North Wales Rock Climbing

Online Guidebook for Rock Climbing in North Wales

This guidebook is brought to you by the topo apps publishing platform in conjunction with LifeInTheVertical, and is authored by Mark Reeves (also author of the coaching book 'How To Climb Harder'). The information contained within this guide should give you nearly a lifetime's worth of climbing across Snowdonia and North West Wales. As well as this web guide there is also a phone app, available for iPhone and Android (with Windows Phone to follow if there is sufficient demand).

Areas Covered

The scope of this guide is for North Wales, and we have concentrated on the classic rock routes of the area from the sea cliffs of Gogarth to the mountains Snowdonia. The areas covered in the first edition of this website are:

The joy of having this guidebook online is of course we can update, alter and correct route descriptions, topos and access information as frequently as we like with the powerful database that drives this website.

The Phone App

As well as keeping this website up to date the database is also at the heart of the phone app, and many people wonder why they should take the time and money to download the app, when all the information is here on the website for free.

Well the app does more than just access the database, when you purchase the app the database is up loaded to your phone, along with the topos and all the information you need. Meaning that there is no need to wait for the topos to upload, which in North Wales may take time and potentially money.

The reason that the download times are slow is that there is no 3G reception in North Wales, in fact at some crags there simply isn't any reception and at Gogarth most phones roam to an Irish Mobile Network, which can be expensive if you are data roaming.

It's not expensive either £6 for an entire guidebook to North Wales, that fits in your pocket, weighs less than any other selected guidebook to North Wales and has interactive maps. For the price of two pints of Beer, the whole of North Wales Climbing is literally right at your fingertips.

Vital Statistics

Of course, there's nothing more compelling than putting down the vital statistics on just what you are getting for your money, and compared to around £25 for any modern guidebook, that £6 is going to seem even more value for money. In the first edition of the guide we covered over 650 routes in 145 topos across 7 major climbing areas in North Wales. In this edition we have added almost 100 more routes, 7 new topos and updated several of the existing ones, taking the opportunity to split the more complex crags e.g. Tremadog into smaller chunks, adding a few new crags and also re-organising the Gogarth section into more logical sections.
To see how these routes breakdown across the areas we have compiled the list below.
