If you are traveling to the island from most places in Fukuoka, you will need to first get yourself to the Meinohama train station. Then, you need to head to the ferry port (my friend drove us - about 5 minutes from the station). According to my online research you can catch a bus from the train station to the ferry stop. You can also bike, but I wouldn't recommend walking.
At the train station, you can buy round trip tickets for the ferry. We had to wait about 20 minutes for the next ferry, and there really isn't anything to do in the ferry station. So you might want to bring a book or music.
The ferry is pretty quick and there is an outside deck if it's a nice day out. Hopefully you plan to go on a nice day, because most of the appeal of the island seems to be that it's scenic and naturally pretty.
When we got off the ferry we caught a bus (this is where it's helpful to have an IC transit card so you just have to swipe it instead of buying a ticket). The bus was very full and the roads were very winding. None of us were happy about that, but it took us all the way to the top of the island. We got to the entrance gate and found we needed to pay to enter the park area. I can't recall exactly how much it was, but I do remember us complaining about it a little. So it wasn't just a hundred yen or anything.
When we arrived the sun was setting. Our friend had been there before and she raced us to a lookout spot so we could watch the sun go down over the water. This sunset was one of the nicest things I have seen in a long time. It was all shades of pink and orange and families were all gathered around peacefully watching as the sun dipped into the water and night fell.
I would recommend bringing a picnic, so that you can snack and relax while enjoying the natural setting. We did this, and after we finished our food we decided to take a walk before heading to the last bus back down to the ferry port. During our walk we found a little tea shop and ordered green tea. It came piping hot and in huge bowls. Needless to say, I burnt my tongue on it, but still it was a delicious way to end our time on the island.
While walking back to the bus stop, my friends and I enthusiastically decided that Nokonoshima would be a really great place to go in the fall. Especially around Halloween. The beautiful setting and abundance of flowers just seems like a nice place to spend a fall day.
At the bus stop there was a huge line. We crammed ourselves onto the bus. Seriously, it was SO crowded. I think they needed to send another one to get the overflow crowd. But you really can't blame everyone for trying to squeeze as much out of the nice spring night as possible.
Conclusion: Nokonoshima is a must on a nice day. There seemed to be a lot to do (shops and such) that we didn't get to explore since we went so late. Bring a picnic and plan on spending a lot of time just enjoying the beautiful scenery.
