camping and caravaning
Dedicated camp sites with security are available in almost all coastal towns and you can often camp in rural areas with a village chief's blessing If you do decide to use this option a small offering such as food, liquor or cigarettes can be very useful.
If taking a caravan keep in mind that a great deal of roads in Mozambique degenerate in to sandy paths that require 4WD, it is advisable to only stick to popular areas along the EN1.
purchasing land or property
If someone offers to "sell" you land in Mozambique walk away immediately, it is a scam. Private ownership of land in Mozambique is impossible, all land is owned by the government and will only be provided for foreign use, under a 99 year lease, under very specific circumstances.
Hotels in Mozambique are generally ungraded and, particularly in the less traveled parts of the country, have not been updated since independence. In some cases you can pay up to $50USD a night for a hotel room that should be in the $5 - $10 range based on facilities. On the other end of the scale Mozambique hosts some of the most incredible, and expensive, hotels and resorts in the world.
