Big boat cruise: the cheapest seat and the easiest with kids. Boats carry dozens to more than 100 people and run about 90 minutes to 2 hours.
Private boat: a captain and your group only, usually up to 4 to 6 people. You can ask to stay longer where the dolphins are.
Jet ski dolphin tour: you drive your own jet ski behind a guide. Drivers usually need to be 16 or 18.
Bottlenose dolphins feed in the Intracoastal Waterway and the Little River and Murrells inlets all year. Morning and late afternoon trips are calmer and cooler in summer.
