Rated #1 on TripAdvisor on Cape Cod — and just 15 minutes from Hyannis — the Whydah Pirate Museum is one of the most genuinely thrilling museums in New England. It houses the world's only fully authenticated pirate shipwreck collection: real gold coins, weapons, and personal artifacts recovered from the Whydah Gally, which sank off Cape Cod in 1717. You can touch 300-year-old pirate coins, step aboard a replica of the Whydah Gally, and watch archaeologists excavate artifacts from the wreck site in the onsite SeaLab. New discoveries arrive every dive season. Admission is $23 for adults, $20 for seniors, $15 for youth (ages 5+), and free for children under 4.

Art Centers & Galleries

Hyannis and the broader Barnstable area have a thriving arts scene that's perfectly suited for a rainy afternoon. The Cape Cod Art Center (374 Route 6A, Barnstable Village) hosts rotating exhibitions, workshops, and classes year-round. The Hyannis Public Library on Main Street often features local art exhibitions in its gallery space. And throughout downtown Hyannis, independent galleries showcase the work of Cape Cod artists — from seascapes and landscapes to contemporary pieces.

A rainy day is also a great excuse to browse the many antique shops along Route 6A through Barnstable Village and West Barnstable — one of the most scenic and historically rich stretches of road on the Cape.
