Explore The Balearic Islands Ibiza Formentera Mallorca Menorca Share Heading northeast from Ibiza Town, it’s 15km to SANTA EULÀRIA DES RIU, a pleasant town with a plush marina but few obvious sights. Though it does boast an attractive church – a fortified whitewashed sixteenth-century construction perched on a hilltop to the west of the town centre, SANT CARLES, 7km to the north, is an agreeable one-horse village. East of Sant Carles the road passes through burnt-red fields of olive, almond and carob trees to several almost untouched beaches. Cala Llenya, a broad sandy cove with sparkling waters, is the nearest, and is popular with families. Tiny Cala Mastella, 2km farther north, is a supremely peaceful spot, with a diminutive sandy beach and crystal-clear sheltered water. Just north of Cala Mastella, Cala Boix is another stunning sandy cove, a little larger and more exposed. Continuing north from Cala Boix, the coastal road follows an exhilarating, serpentine route above the shore, through thick pine forests and past the lonely nudist beach of Aigües Blanques.
