We can support with....
Orientation
Because you need information about the place to visit.
Transportation
Because you need to transport yourself to that place.
Guide
Because in many of the places there are no clear paths to go.
Mountain Equipment
Because you may need a tent, a sleeping bag or trekking poles.
Feeding
Because some places have restaurants and cooks.
Health Emergency
Because you will never be able to anticipate it and you will need help.
Accommodation
If you can sleep more comfortable why not?
