Trip in june, suggest places please!

We are 4 friends, all turned 18 recently, we are going for a trip in June. Cannot decide the place

We want it to be a beautiful nature place, like mountains, lakes, small treks, canyons and pure uncensored nature.

We don’t want a very crowded or cliche place like manali, something good, not extremely crowded, nature place.

We first wanted to go to meghalaya but its really far from our city (like a 35 hour train to reach there)

And also june is not the best time to visit Meghalaya so we kind of cancelled it.

Then we are thinking of kerala, not really sure about it tbh.

Can you please suggest us places in India which is safe, also adventurous, and in the heart of nature.

We will be going in a group travel package too.

We also have 2 girls in our group so- cannot risk safety.
