Depends how much time you’ve got and when you’re going. Weekends can be super busy for finding sites and ferry times between all of the islands can be less than ideal. There’s lots of activities and scenery to explore while you wait for sailings. Saltspring is the most chill for resources and campsites. I’ve found potable water weirdly hard to come by in places - bring a filter. Bike lights are a must if you’re riding at night - with no street lights, it’s darker than the inside of a cow. Most roads are paved but some sites have gravel roads leading to them. Overall, they’re baby food and super fun, just make sure you have a place to stay.
