For a deeper look into the history of this seaside retreat, take a trip to the Rehoboth Beach Museum. The small museum displays everything from vintage bathing suits to archaeological artifacts that date back to the settling of the area. The museum also offers rotating exhibits that showcase the area's rich history as a vacation destination, such as a display of vintage Rehoboth Beach postcards that span more than 100 years.  

Recent visitors described the museum as quaint and said it's a good activity for a rainy day. The museum is located  just off Rehoboth Avenue, a few blocks west of the Dogfish Head Brewing Company. Admission is free, but donations are accepted. The museum's hours vary by season, but generally, it's open from 10 or 11 a.m. to 3 or 4 p.m. To learn more, head to the museum's website.
