Off the road leading into Port de Sant Miquel (Puerto de San Miguel) is Cova de Can Marça (tel. 97-133-47-76; www.covadecanmarsa.com), about 91m (300 ft.) from the Hotel Galeón . There is a fine view of the bay from the hotel's snack bar. After a stunning descent down stairs clinging to the cliff's face, you enter a cave that's more than 100,000 years old and forms its stalactites and stalagmites at the rate of about .6 centimeter (1/4 in.) per 100 years. A favored hiding place for smugglers and their goods in former days, it's now a beautifully orchestrated surrealistic experience -- including a sound-and-light display -- not unlike walking through a Dalí painting. Many of the limestone formations are delicate miniatures. The half-hour tour is conducted in several languages for groups of up to 70. From Holy Week to the end of October, tours are offered daily every half-hour from 11am to 6pm. Admission is 8€ for adults and 4.50€ for children.
At the island's northern tip is Portinatx, a pretty series of beaches and bays now marred by a string of shops and haphazardly built hotels. For a taste of its original, rugged beauty, go past all the construction to the jagged coast along the open sea.
Every Saturday year-round there is a flea market just beyond Sant Carles (San Carlos) on the road to Santa Eulalia. (You'll know where it is by all the cars parked along the road.) Open from about 10am until 8 or 9pm, it offers all kinds of clothing (both antique and new), accessories, crafts, and the usual odds and ends.
A beautiful drive leads from Sant Carles (San Carlos) along the coast to Cala Sant Vicent (San Vicente).
Escaping from the Hordes
If you want to escape to a lovely beach that remains a stranger to hotel construction, head for Playa Benirras, just north of Port de Sant Miquel. An unpaved but passable road leads out to this small, calm, pretty cove, where lounge chairs are available and pedal boats are for rent. On the beach are snack bars and restaurants.
