אם תרצו לראות את הזריחה וגם את השקיעה, כדאי שתישארו שם לילה אחד.

This is a very common point of confusion.

In Hebrew, after אם (if), a real future condition is usually expressed with the future tense:

• אם תרצו = if you want / if you will want
• אם תלכו = if you go
• אם תראו = if you see

So even though English normally uses the present after if, Hebrew often uses the future.

That means:

• אם תרצו לראות... literally looks like if you will want to see...
• but it is naturally translated as if you want to see...

תרצו is second person plural future: you (plural) will want.

So this sentence is addressed to more than one person.

Related forms:

• אם תרצה = if you want (masculine singular)
• אם תרצי = if you want (feminine singular)
• אם תרצו = if you all want

The same thing happens later with שתישארו, which is also plural.

After verbs like רוצה / ירצה / תרצו (want), Hebrew usually uses an infinitive for the next verb.

So:

• תרצו לראות = you will want to see
• רוצה לאכול = wants to eat
• רוצים ללכת = want to go

Here, לראות is the infinitive to see.

This is very similar to English:

• want to see
• want to stay
• want to go

את marks a definite direct object in Hebrew.

Since both nouns are definite:

• הזריחה = the sunrise
• השקיעה = the sunset

they need את when they are direct objects of לראות (to see):

• לראות את הזריחה
• לראות את השקיעה

A very important point: את is not translated into English. It is just a grammar marker.

Compare:

• אני רואה זריחה = I see a sunrise
• אני רואה את הזריחה = I see the sunrise

Because both items are definite direct objects, Hebrew normally marks each one with את:

• את הזריחה וגם את השקיעה

This is the clearest and most standard way to say it.

You will often see את repeated when two definite objects are joined:

• ראיתי את הסרט ואת הסדרה
• קניתי את הספר וגם את המחברת

So the repetition here is natural and correct.

גם means also / too.

וגם literally means and also.

In this sentence:

• את הזריחה וגם את השקיעה = the sunrise and also the sunset

It adds a sense of not only one, but the other one too.

You could think of it as emphasizing that the speaker means both:

• sunrise
• and also sunset

כדאי is a very useful word. It often means:

• it’s כדאי = it’s advisable
• it’s worth it
• it would be a good idea
• sometimes simply you should

In this sentence:

• כדאי שתישארו שם לילה אחד means something like
• you should stay there one night
• it would be a good idea to stay there one night
• it’s worth staying there one night

So כדאי is not exactly the same as a strict command. It sounds more like a recommendation.

The ש is the conjunction that.

So:

• כדאי שתישארו שם = it is advisable that you stay there
• literally: it’s worthwhile/ advisable that you will stay there

Hebrew often uses כדאי ש... + future verb.

Another very common alternative is:

• כדאי להישאר שם לילה אחד = it’s worth staying there one night

So both patterns are common:

• כדאי שתישארו...
• כדאי להישאר...

תישארו is the future, second person plural form of להישאר (to stay / remain).

So:

• להישאר = to stay
• תישארו = you (plural) will stay

In this sentence, because it comes after כדאי ש..., it is best understood as:

• that you stay
• that you should stay

Related forms:

• תישאר = you will stay (masculine singular)
• תישארי = you will stay (feminine singular)
• תישארו = you will stay (plural)

Because Hebrew often uses the future tense after words like ש in recommendation-type structures.

So although תישארו is formally a future form, in context it can express something like:

• that you stay
• that you should stay

This is normal Hebrew usage. The exact English translation depends on context, not just on the verb form by itself.

In Hebrew, the number one usually comes after the noun:

• לילה אחד = one night
• יום אחד = one day
• שנה אחת = one year

So the natural order is:

• noun + אחד/אחת

Also notice agreement:

• לילה is masculine, so it takes אחד
• a feminine noun would take אחת

For example:

• פעם אחת = one time

Hebrew often uses a bare time expression where English may say for.

So:

• להישאר שם לילה אחד literally: to stay there one night
• natural English: to stay there for one night

This is completely normal in Hebrew. The preposition is often unnecessary.

Compare:

• חיכיתי שעה = I waited an hour
• נשארנו יומיים = we stayed two days

Yes. שם means there.

So:

• להישאר שם = to stay there

It is a very common adverb of place.

Compare:

• פה / כאן = here
• שם = there

Yes, absolutely.

Both are natural, but they feel slightly different:

• כדאי שתישארו שם לילה אחד = you should stay there one night

  • more directly addressed to the listeners

• כדאי להישאר שם לילה אחד = it’s worth staying there one night

  • a little more general or impersonal

In many situations, either one would work.

The sentence has two main parts:

1. אם תרצו לראות את הזריחה וגם את השקיעה
   = if you want to see the sunrise and also the sunset

2. כדאי שתישארו שם לילה אחד
   = it would be a good idea for you to stay there one night

So the overall pattern is:

• If X, then it’s advisable to Y

This is a very common Hebrew structure:

• אם תרצו..., כדאי ש...
• If you want..., you should...

It is mostly neutral and natural modern Hebrew.

Nothing in it is especially slangy or especially formal. It would sound fine in travel advice, conversation, or writing.

The only thing to notice is that כדאי gives it the tone of a recommendation, not an order. So it sounds helpful and natural, like advice:

• If you want to see both, you should stay there one night.
