Czech Hiking Markers System

Colored markers throughout the trail accompany the hiker - this is the blue marked trail

The trail usually starts with arrow signs with names of destinations and number of kilometres marked. Each trail is then color marked by simple markers and arrows painted between white lines (for better visibility) on fixed objects along the trail (trees, rocks, utility posts or walls) in a color given to a specific trail.

The basic system of trails with markers painted along the trail can be complemented by other features. These additional features are not necessary for the basic functioning of the system though.

• Information boards along the trail, giving information about the trail, nature protection, monuments, animals and trees along the trail. Logos of the supervising institution can be shown.
• Printed Maps with colored lines showing the trails.
• GPS information on each trail, board or sign
• Mobile phone application with a map and site descriptions (electronic tourist guide)

This method of trail blazing has a wide international usage in most of Central and Eastern Europe (including the Balkans and Caucasus), with showcase examples also in parts of Latin America and Asia.

The system has been used by the Czech Hiking Club since 1888.[1] The entire territory of the Czech Republic is covered with marked trails,[2] and detailed maps are published and widely available. In the Czech Republic, over 70,000 km of hiking trails have been marked in this way. Of these, 39,816 km of hiking trails were marked in 2008. An additional 31,104 km of cycling trails, 387 km of skiing trails, and 1300 km of horse riding trails are also marked. In 1938 it was the longest system in the world,[3] but now it is the densest network.[3]

Maps of the trails have also been made into a number of digital applications - both Apple and Android for mobile phones, on Google Maps,[4] and on the Czech "Mapy.cz" (and its version for foreigners called "WindyMaps").

This system uses three bars - usually one color in between two white bars,[5] with different meanings attached to different colors:[6]

• red indicates the most difficult or summit trails;
• blue for difficult trails;
• yellow and green for easy or interconnecting trails.

These marks may be posted on wooden boards or metallic plates.

Basic Marker - Red color used for difficult or summit trails

Basic trail markers are square, 10x10 cm in size. The volunteers marking these trails usually prepare sheet metal or cardboard matrices to keep the signs uniform in size.

Any change of direction is marked with arrows of the same color and similar design.

The system is usually supplemented by maps,[2] which show the trails as lines in corresponding colours. Nevertheless, maps are not necessary for the system to function, as walkers can simply follow the trail from marker to marker.

Due to the relative ease of use and low cost, the system has spread to many other countries, often by Czech people. Originally used in the Czech Republic, the system spread through Central Europe and Eastern Europe and even to countries outside Europe. Nearly identical systems exist in the neighbouring countries of Austria and Poland.

• Austria's standard is almost identical, with red-white-red stripes used instead of white-red-white[7] The same colours are used in the Czech Republic for cycling trails.
• Azerbaijan.[8]
• Brazil.[9]
• Bosnia - Maglić Mountain
• Bulgaria[10]
• Croatia[10] especially on the island of Krk, with a map available in local tourist centers.[11] The Czech Tourist Club marked a network of historical goat trails that can now be used by tourists hiking in the mountains.
• Czech Republic - fully covered with marked trails and detailed maps and the densest trail network in the world
• Georgia - Caucasus trails marked by Czech volunteers, particularly the mountain border between Georgia, Ingushetia, Chechnya and Dagestan.
• Hungary[12]
• Israel - trail markers are larger (approximately 20x15 cm) but based on the same three stripe scheme. Long trails replace one of the white stripes with purple (regional) or orange (national).[13]
• Peru
• Philippines[14] - Three new trails were marked to showcase the system on Mt. Kanlaon Volcano, Negros Island, with the trail marked by Czech volunteers from Mendel University, in cooperation with the Czech Embassy. Additional new and more extensive trails have been marked in 2017;
• Poland[15] - these markers are especially common on trails near the Czech and Slovak borders.[16][17] The system is a slight expansion of the Czech model, adding black to the four colors used in the Czech markers.
• Romania - 300-400 km of trails marked by the Czech Tourist Club in the Banat region,[18][19] as well as a 360 km mountain trail leading from Slovakia across Ukraine to Romania.[20]
• Slovakia[21] fully covered with marked trails and detailed maps
• Switzerland uses a modified form with blue marking Alpine trails, which are more difficult than red trails
• Ukraine[22] especially in Subcarpathian Ukraine[23] and Crimea[24] with some 700 km of trails marked in 2011 in Subcarpathia and continuing efforts by Czech, Ukraininan and Polish volunteers to mark additional routes with part of the program sponsored by the Czech Ministry of Foreign Affairs. Maps of the trails are available.[25]
