يا نخيم في الوادي يا نطلع للقمة.

Here يا ... يا ... means either ... or ....

So:

• يا نخيم في الوادي
• يا نطلع للقمة

means either we camp in the valley, or we go up to the summit.

This is a very common colloquial pattern in Arabic.

It is the same spelling, but not the same function.

• يا أحمد = O Ahmed / hey Ahmed
• يا ... يا ... = either ... or ...

So in your sentence, يا is not calling anyone. It is marking two alternatives.

Because the verbs already include we.

In Egyptian Arabic, the prefix نـ on a present-tense verb often marks we.

• نخيم = we camp
• نطلع = we go up / we climb

So Arabic does not need a separate word like English we here.

In Arabic, the present tense is often used for:

• plans
• suggestions
• possible future actions
• immediate decisions

So يا نخيم ... يا نطلع ... can naturally mean either we camp ... or we go up ... even though the action has not happened yet.

If you wanted to make the future more explicit, Egyptian Arabic could also use هنـ:

• يا هنخيم في الوادي يا هنطلع للقمة

But the original sentence is still natural.

نخيم means we camp or we set up camp.

It comes from the verb خيّم meaning to camp. In context, it suggests staying in the valley as a camping spot, not just sitting there briefly.

In careful spelling, you may see نخيّم with a shadda, because the verb is from خيّم.

But in everyday informal writing, people often leave out:

• shadda
• short vowels
• some other spelling details

So نخيم and نخيّم can represent the same word in casual writing.

Here نطلع means go up, head up, or climb up.

The verb طلع is very common and can have several meanings depending on context, such as:

• go up
• come out
• appear
• rise

In this sentence, because of للقمة, the meaning is clearly go up to the summit.

Because the two verbs take different prepositions in this context.

• خيّم في = camp in
• طلع لـ = go up to / head toward

So:

• نخيم في الوادي = we camp in the valley
• نطلع للقمة = we go up to the summit

This is not unusual. English also changes prepositions depending on the verb.

للقمة is made from:

• لـ = to
• الـ = the

When they come together, they become للـ in writing.

So:

• ل + القمة
• becomes
• للقمة

This is a very common combination in Arabic.

In careful or more formal reading, it is al-qimma or el-qimma depending on style.

In everyday Egyptian pronunciation, ق is often pronounced as a glottal stop, so القمة may sound more like:

• el-ʔimma

So a learner may hear something closer to lil-ʔimma in the full phrase للقمة.

The spelling usually stays the same even when the pronunciation changes.

It is closer to everyday spoken Arabic, especially because of the simple يا ... يا ... alternative structure and the conversational feel.

A more formal or Standard Arabic version might be something like:

• إمّا أن نخيّم في الوادي وإمّا أن نصعد إلى القمة

That sounds more written or formal. The original sentence sounds more natural for speech.

It is quite natural for discussing options, especially in a practical situation like travel, hiking, or camping.

It sounds like people deciding between two plans:

• stay lower and camp
• keep going up to the top

So the sentence feels direct, conversational, and realistic in spoken Egyptian Arabic.
