I'm going to Korea later this month and thinking about adding roughly a week for a Jeju stay before or after my appointment. Given the choice of the week of March 24th and April 7th, when would be a better time to visit? I hear the spring flowers are supposed to be in full bloom at the end of March which I'm interested in. But I'm wondering if the weather would be much nicer later in April. I would most likely be spending much of my time outdoors hiking and cycling. Also, I don't know yet what kind of snorkeling possibilities are in Jeju but would like to try if the water is warm enough. With this in mind, will there be much difference in terms of weather and water temperature between the two weeks I am considering?
Thanks for any input.
By the way, I'll be in Jeju on my own. Would staying at a Minbak/guest house increase my chances of meeting other solo travelers? Or are there some hotels that are less family/couple-oriented than others?
