Ordnance Survey maps provide the most accurate and up-to-date geographic data so it is worth kitting yourself out with these before your climb. The OS maps required for the national three peaks challenge are:
- OS Explorer Map 392 – Ben Nevis and Fort William
- OS Explorer Map OL6 – The English Lakes: South Western Area
- OS Explorer Map OL17 – Snowdon
You can also buy these maps direct from the Ordnance Survey website. Aswell as OS maps, they also provide digital maps (including maps for iOS devices), GPS devices, guide books, compasses, clothing and accessories.
If you’re looking for a 3 peaks map bundle for your team it is also worth checking out Beacon Maps as they provide some very clear maps together with tips and useful information.
Spend some time learning how to navigate properly using a compass – it is common to experience misty, damp and snowy conditions near the summits with poor visibility and in these conditions you will need to take compass bearings to find your route safely. If you plan on taking a GPS device, take spare batteries with you but don’t rely on this as your sole navigational device in case you lose a signal or the battery power – always take your map and compass as a backup.
If you are at all unsure about navigating proficiently please consider hiring a Mountain Leader
