There may be natural areas of free-standing rocks, which allow nimble walkers to jump or step from one to another, improved if necessary by rocks placed to fill wide gaps. Such areas should be chosen where the rock is rough, and not colonized by slippery algae. Stepping-stones can also be placed in stream crossings, where […]

Stream crossings
In most circumstances where water has to be crossed special structures should be provided, such as culverts as previously described, some kind of ford, stepping-stones or other informal means, or bridges. In wilder, more rugged terrain, where primitive experiences and a greater expectation of selfreliance on the part of visitors are expected, crossing streams can […]
Handrails
Handrails serve two functions: as aids to negotiating difficult sections of the trail, such as steep pitches or steps, and as safety barriers to prevent people from falling. Along most paths, handrails should be unnecessary, but they are needed where steps are steep, where boardwalks or bridges are raised more than 500 mm (18 in.) […]
Other forms
Other forms of steps that are found in severe terrain include steel ladders bolted to rock faces, and iron steps set into rock. Such sections are almost always on pitches where rockclimbing skills are needed. They are not for the faint-hearted, but they do give non-climbers a taste for exciting ascents and Г^-П фІ- […]
Timber
This can be used in a number of ways. One version to be avoided is the use of round or half-round timber as edge retainers. These offer no grip, and under wet conditions they are extremely slippery and dangerous. Steps have frequently been constructed of stout sawn boards laid on their edges to form a […]
Natural stone
This is the best, most hard-wearing material, which blends into many landscapes. In the most rugged and mountainous terrain, steps can be very irregular in size and shape, so that they Stone paving: (a) A section and plan of paving using natural stone. A level surface is achieved by laying the irregular stones at various […]
Steps, ramps and changes in level
Every effort should be made to achieve reasonable gradients on trails to enable their widespread use by people with a range of abilities. In steeper, more rugged terrain and places where rock outcrops occur, there may be no alternative to the construction of steps or stepped ramps. However, long runs of steps going vertically up […]
Sloping ground in mineral soil
In these circumstances excavation to create the trail is necessary, and gradients need to be controlled. If possible, gradients should be found that preclude the need for steps. After initial clearance and pruning of vegetation, the route is set out with canes and the gradient checked using a simplelevelling instrument such as an Abney. Then […]
Causeway construction
As a last resort in the worst places, where peat cannot support a raft, causeways can be constructed. If there is a subsoil the peat can be removed down to it and set on one side. Soil is then excavated along both sides of the proposed path route and piled in the middle until it […]
Fascines or faggots
This is a method that has been used for hundreds of years. Bundles of brushwood, slash from logging or similar materials are compressed tightly and bound using wire or nylon twine. The faggots are laid side by side lengthways across the path. They should be longer than the path width, because light wooden poles of […]
