Thames Path OS Explorer

Explore and navigate Thames Path with confidence using this genuine Garmin GB Discoverer map which comes supplied on SD card.

Simply insert the microSD/SD card into your compatible Garmin unit and you are ready to walk, hike, ride or hack the Thames Path with an OS map at a scale of 1:25K - as recommended by Ordnance Survey for outdoor activities.

Thames Path GB Discoverer map covers the shaded area number 32 on the UK map to the right.

What the Thames Path map provides

When inserted into a compatible Garmin device the GB Discoverer Thames Path maps provide Ordnance Survey (OS) maps at a scale of 1:25 000 for the entire Park or Trail area. Plus a 1:50 000 scale map for the same area and slighly beyond that area. The map data is the same as the scale found in the OS Explorer Map series (same as the OS orange cover paper maps ). Rather than having folding paper maps to deal with, OS maps are all on your Garmin screen and in the palm of your hand.

As an added bonus this map also includes OS mapping for ALL of Great Britain - but at a lesser scale of 1:250 000 and 1:1000 000. This OS mapping is viewable down to the 0.8mile resolution of a Garmin handheld (e.g. in a Garmin Colorado and a Garmin Oregon). Any closer than 0.8mile, e.g. 0.5miles, and the mapping reverts to the (also included) NAVTEQ road mapping - still very useful, with road names - AND don't forget that this is for ALL of Great Britain, not just the specific National Park or Trail which this map covers at 1:25K.
