There are many different types of meditation (just like exercise)! I started by attending drop in sessions in different traditions (Zen, Insight, Yoga, Spiritual) and after some trial found the meditation type that works best for me (Insight).
Below are 2 retreat centers in North America in the Insight tradition that offer retreats. I would suggest starting with a short, introductory (2-3 days) course at one of these locations. These locations are very well recommended by fellow mindfulness teachers though I have not personally taken a course there. They are very popular and often have a waitlist for courses.
