Internships and crazyness in croatia??

Hello guys!

I AM 24 years old. Just finishing my college degree and I have the possibilitou to go to croatia to do and internship. The regions whre i can go to is istra, knin, moslavnia, varazdin.

Right now focusing more on Istra. So I AM portuguese from the island of Azores but have been studying last 6 years in Lisbon. Lisbon os great but I AM getting tired of it.

I want to know what i Will find in croatia and whats the best location for:

• 1) nature, some sunny beaches and some lovely trees to go look at. Is it to complicated to reach such spaces and do some related sport activities?

2) whats the typical night in croatia? I really like being out on the street drinkong and chattin, typical clubbing is not my thing. I prefere Nice alternative kind of places

3) is it easy to travel to other places ot travel inside croatia?

Im probably going from january until the summer.

Thanksss
