어쨌든 means anyway, in any case, or regardless.

In this sentence, it gives the feeling of:

• No matter what
• After all that
• Whatever happens

So it sounds like the speaker is brushing aside other concerns and saying something like:

• Anyway, let’s make it to the top today.

It is often used when:

• there has been discussion, hesitation, or difficulty
• the speaker wants to return to the main point
• the speaker wants to push forward despite circumstances

A few similar words are:

• 아무튼 = anyway
• 어쨌거나 = anyway / in any event

These are close in meaning, though the exact tone can vary a little.

Yes, 정상 can mean two different things:

1. summit / peak / top
2. normal / normal state

In this sentence, it means summit or top.

That is clear because of the context and because it is followed by 까지, which marks a destination or endpoint:

• 정상까지 가다 = go as far as the summit / go to the top

So here, 정상 is definitely the mountaintop, not normal.

-까지 often means:

• up to
• until
• as far as
• sometimes even

In 정상까지, it marks the endpoint of movement:

• 정상까지 가다 = go all the way to the summit
• go as far as the top

This makes the sentence sound a bit stronger than just 정상에 가자 in some contexts, because 까지 emphasizes reaching that limit or final point.

Compare:

• 집에 가자 = let’s go home
• 집까지 가자 = let’s go all the way home / let’s go as far as home

So here, 정상까지 highlights the goal: the summit is the point we want to reach.

가자 is the plain-style let’s go form.

It comes from the verb 가다 (to go) and expresses a suggestion or proposal:

• 가자 = let’s go

Comparison:

• 가자 = casual / plain / intimate
• 갑시다 = formal let’s go
• 가요 = usually go in polite style, not normally let’s go

So if you want to say let’s go politely, you would usually say:

• 갑시다

If you are talking to a friend, teammate, or someone close, 가자 sounds natural.

In this sentence, 가자 gives a direct, encouraging, possibly determined feeling:

• Come on, let’s make it to the top today.

Yes. Korean often leaves out subjects when they are understood from context.

In 어쨌든 오늘 정상까지 가자, the implied subject is usually:

• we

So the full idea is:

• Anyway, let’s go to the summit today.

But Korean does not need to say 우리 (we) here unless the speaker wants extra emphasis.

Natural Korean often omits:

• subject
• object
• other information that is already clear

That is very common and natural.

Time words like 오늘 (today) often appear with no particle at all.

So:

• 오늘 가자 = let’s go today

This is completely normal.

You could add a particle if you want a different nuance:

• 오늘은 = as for today / today at least
• 오늘도 = today too
• 오늘만 = only today

But in a neutral sentence, no particle is very common.

So:

• 어쨌든 오늘 정상까지 가자 sounds natural and simple.

Yes. Korean word order is flexible compared with English, especially as long as the sentence ending verb stays near the end.

This sentence is:

• 어쨌든 오늘 정상까지 가자

But you could also hear variations like:

• 오늘 어쨌든 정상까지 가자
• 정상까지 오늘 가자 (less neutral depending on context)
• 오늘 정상까지 어쨌든 가자 (possible, but less natural in many contexts)

The most natural order usually puts:

• adverbs like 어쨌든 toward the front
• time expressions like 오늘 before the verb
• destination phrase like 정상까지 before the verb
• verb at the end

So the original sentence has a very natural flow.

It sounds:

• casual
• determined
• encouraging

Because of 어쨌든, there is a sense of:

• despite everything
• no matter what
• let’s push on

Because of 가자, it sounds like a proposal, but it can also feel motivational, especially in a difficult situation like hiking or climbing.

Depending on context, it could sound like:

• encouragement to a companion
• determination shared by a group
• the speaker talking themselves and another person into continuing

So the tone is not just let’s go. It often feels more like:

• Anyway, let’s do it. Let’s make it to the top today.

They are close, but not exactly identical in nuance.

• 정상에 가자 = let’s go to the summit
• 정상까지 가자 = let’s go as far as the summit / let’s make it all the way to the summit

The -까지 version emphasizes the endpoint more strongly. It can suggest:

• the summit is the final target
• the speaker is focused on reaching that exact limit
• there may be effort or difficulty involved in getting there

So in a climbing or hiking context, 정상까지 가자 often feels especially natural because it stresses reaching the top.

It is commonly pronounced roughly like:

• eo-jjaet-deun

In actual speech, the ㄷ in 든 is affected by the following sounds, so it often sounds closer to:

• 어쨌뜬

You do not need to overthink the spelling-pronunciation difference at first, but it is useful to know that connected Korean speech often changes sounds naturally.

Yes.

가자 can be used:

• to invite someone else: let’s go
• to encourage a group including yourself
• sometimes even as self-motivation: come on, let’s go

So depending on context, 어쨌든 오늘 정상까지 가자 could mean:

• the speaker is talking to a friend
• the speaker is talking to a group
• the speaker is psyching themselves up

That flexibility is very natural in Korean.
