On this trip, you'll discover how Isola Rossa got its name. After boarding a dinghy at the harbour, you'll sail along Sardinia's north west coast. From the boat, you'll be able to see how the seaside of white sand is backed by a fringe of red rock formations. The rock is red granite, and its colour makes you feel like you're looking at the coast through rose-tinted glasses. Your guide will point out Marinedda Beach, which is one of the prettiest easily-accessible bays in the area. You won't stop here, though. Instead, you'll pull up at a much more exclusive beach :one you can only access by boat. Tinnari Beach is a small smile of sand and pebble, secluded from the rest of the world by a screen of cork trees. You'll have time to unroll your towel for a spot of sunbathing or to take a dip in the sea.
