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.

The island's administrative capital is nestled beautifully on La Palma's east coast, and is dotted with museums and quaint churches. Do not miss the best vantage point for seeing Santa Cruz in its entirety at 17th century Santuario de la Virgen de las Nieves, and stroll down the Avenida Maritima to see its colourful, idyllic balconies festooned with plants and flowers.

Today's Wooden Palace of Tsar Alexei Mikhailovich is a complete reconstruction, since the building's original was, sadly, demolished on command of Catherine the Great in the 18th century. The museum inside showcases the lively embellishments and ornate furniture that was replicated through paintings dating back to the time.

If you yearn for gold, velvet and precious stones, you must visit the Armoury. The treasures that have been collected over the centuries by the Russian tsars and princes can be found here. Some magnificent examples are the Fabergé egg and Catherine the Great’s coronation dress.
