Maui is really family oriented. Take a stroll down Kaanapali Beach and you will find lots of young families vacationing. The dress code is casual and the paths are stroller friendly. I suggest you bring a stroller if you have little ones. It makes trips to the beach and restaurants easily accessible. Everything is paved and wide enough to maneuver.
Activities
We knew we would spend most of our time at the beach and the pool, but we also wanted to venture out a little.
Luau-
We went to the Drums of the Pacific Luau at the Hyatt Regency. I suggest going to a luau if you never have been. If you have, they are all very similar. This was my third luau, and it was good. The food was good, the drinks were all-inclusive(my husband partook), and the entertainment was funny. It was walking distance from our hotel and was very convenient. It started in the evening and lasted about three hours long. Our little man got a little squirrely towards the end, but we were able to enjoy ourselves as a family. My son also got a free Hula lesson that was adorable and fun.
Hiking Iao Valley-
I wanted to go on a hike with my family while in Maui, but nothing to long and strenuous. We decided on Iao Valley, and I am glad we did. The trail is less than a mile long with beautiful views and flora. The drive took about 40 minutes from Kaanapali and you pay about $10 to enter the state park. Once there, the is a paved path, and an unpaved path. It takes you to the top of Iao Valley for a picture of the needle, and you can visit the river as well.
Snorkeling:
Black Rock and Kaanapali Beach
At the end of the path in Kaanapali Beach, we were able to snorkel as a family of three. Black Rock is great for beginners. You can wade into the water and practice your skills with your mask. My son and I wore life vests to focus on the fish below and not to worry about our swimming skills. There were an array of fish very close to shore. We were able to take the GoPro and video my son snorkeling and looking at fish for the first time. THe waves were small and we could float around easily. It does get busy with lots people, but the morning seemed to be the best time to go. On our last trip we were able to see turtles, but no such luck this time. There is a rocky cliff that shelters the ocean current on one side. Every night at sunset, a cliff diver lights the torch and dives into the water. I recommend watching this cultural experience and hearing the story that goes along with it. If you are an experienced snorkeler, I recommend the boat tours offered. As a honeymooners, this experience offered more venues to swim and more fish/wildlife to see. As a pregnant lady with a three year old, Black Rock suited us perfectly. When our son got tired of swimming and hungry for lunch, we just walked back to our hotel as short distance away.
