How long to explore Aruba?

I know it would never be enough time to enjoy all the beauty and attractions of Aruba. But, how long does it take to completely explore the most important and attractive places in the island?

I have about 2 weeks in Aruba and want to know what I should see first. What is most important to see and what needs the most time? Everything looks gorgeous but I could love the opinion of someone who has travelled there rather than just the vacation companies. Thanks for the help!

I guess one month is not enough for me to visit all nice places in Aruba. To think the island is not too big but it's full of natural beauty. It took me almost a week to hike in Hooiberg and another week to explore Arikok National Park. I think 2-3 months is probably enough to explore breathtaking beauty of Aruba.

I just checked out Hooiberg and it looks breathtaking! Did it take a guided tour or did you just trek up on your own? Also, can you do it in less days than that?
