Cape Cod packing list for families
Cape Cod summers mix warm sand with chilly ocean water and breezy evenings, so a good bag has fleece next to the swimsuits. Here is what our family packs for the bay, the beaches, and the boats.

Kristina's notes on Cape Cod
- For little kids, I steer families to the bay side. The water is calmer and warmer, and at low tide the flats stretch out for a long way, perfect for crabs and tide pools.
- Ocean beaches on the Outer Cape are colder, with strong surf, and seals and sharks are part of the landscape. Read the posted signs and swim near lifeguards.
- Saturday is changeover day for most rentals, and bridge traffic can back up for hours. A midweek arrival saves a lot of car time with kids.
