Every island offers you an abundance of choices—luckily, you can’t go wrong when deciding what to do in the San Juans! The shorter your stay in the islands, the more important it is to plan ahead. Booking activities, lodging, and dining in advance will make your trip run smoothly and you'll be more likely to get your first picks. Most tour operators have generous cancellation policies in case you need to make changes. (Check with individual companies to be sure of their policies.) Find island transportation options here.
