You can visit Iona on a day trip from Mull, or you can spend some time there in one of the small inns, or you can do what we did -- apply to participate in the Iona Community for a week, in which case the Abbey Church will become a central part of your life.
If you stay on the island, you are welcome to attend any of the morning and evening services at the church. If you stay with the Community, you will be housed in either the Abbey or the nearby MacLeod Center, where we stayed, and you'll participate in meal and clean-up chores and a relaxed week of programming and community life.
Our church's Music Director is enamored of the Iona Community and Taize' music often sung in the Abbey church. I think we were all moved to find ourselves participating in worship services in a place where Christianity had been practiced for 1500 years and to sing songs that we had learned in a contemporary world an ocean away.
