Casa Ybel Resort was built as Sanibel's first beachfront resort, so it enjoys one of the best locations on the island. The on-site amenities fulfill almost every vacation need. Sanibel and neighboring Captiva Island are considered to be two of the top three shelling locales in the world. Walking and biking along naturally landscaped paths are other popular island pastimes. Be sure to visit the J.N. "Ding" Darling National Wildlife Refuge, which protects more than 200 species of birds. Sanibel Island offers many unique shops and dining establishments.
