My husband and I spent a week in Oahu for our 25th anniversary - be sure to stop at Leonard’s Bakery (yummy - guava cake and hot melasada Portugese donuts).
We did the Diamond Head hike - I was so worried about doing this because we had read the reviews before hand (proper footwear, when to go, hydration, etc.) - people were climbing it in flip flops while carrying babies!
Dole Plantation - we didn’t do the tour, but did stop at their gift shop and had a few pineapples sent home - delicious!
Hanauma Bay snorkeling - loved it but remember that the water was quite chilly (we went in January)
North Shore - we just parked on the side of the road and sat on the beach for a couple of hours watching the surfers - unbelievable!
Pearl Harbor - no words
