Christmas Island is one of the world's truly spectacular tropical seabird rookeries. It's not just the number and variety of seabirds or their magnificent splendour that make the island so remarkable, but also their sheer visibility. Around 80,000 seabirds nest here annually, with 23 breeding or resident species. Birds can be seen and heard everywhere on the island, at just about any time of the day. With just a little effort, birdwatchers can easily tick off a full list of residents in a busy week or a more relaxed fortnight. However, the elusive Christmas Island hawk owl keeps many coming back. More than 100 vagrant and migratory bird species have been recorded here, including eight breeding seabird species and one subspecies. The most numerous is the wide-ranging red-footed booby, which nests in colonies in trees in many parts of the coastal shore terraces. You may see the endangered Christmas Island frigatebird soaring above Settlement — it's the world's rarest frigatebird and nests only on the island. The golden form of the white-tailed tropic bird is an endemic subspecies unique to Christmas Island. Known locally as the golden bosun bird, this stunning bird is graceful in flight and has been adopted as the island's fauna emblem.

Boats travel along the shores of the Bosphorus from Eminönü, they chug quietly under the bridges that connect Europe and Asia. One hour away is Anadolukavağı, a little Asian fishing village with lots of pleasant restaurants. You can travel to the largest of the Prince Islands with a Seabus, departing from Kabataş below the Dolmabahçe Palace. Ferry terminals in Eminönü and Karaköy on either side of the Galata bridge are good starting points for exploring Istanbul by ferry.

The Galata Tower is a medieval stone tower in the Galata/Karaköy quarter of Istanbul, just to the north of the Golden Horn's junction with the Bosphorus. The top floor of the tower is located at a height of 52 metres and houses an observation deck. It is unlikely that you will find a better lookout spot in all of the city; it's simply stunning. The tower is one of the most iconic buildings in Istanbul and is a very popular destination. It's a good idea to come early in the morning to avoid the crowds.

This relatively unknown valley is home to several charming small towns including Ricote, Ojós and Abáran. The landscape is dotted with leafy fruit farms, and the surrounding hills are popular for hiking and mountain biking.
