7

There are five directions. You know where north is because of the compass at the bottom of the diagram. You also know where you start.

You first need to work out which of the instructions cannot be the first instruction. The one which says ” the first green tent you come to…” is clearly the end of the instructions, so that cannot be the start. The one about the blue tent starts with “keep going”, so that cannot be the first instruction. The one about the yellow tent starts with “at the next junction”, so that cannot be the first instruction.

If you start by taking the path to the left of the red tent then none of the other instruction make sense at the next junction.

The only order which works is: NE, red tent, yellow tent, blue tent, green tent. This leads you to section 7.
