Oman stands among the oldest independent states in the Arab world, with evidence of human habitation stretching back over 100,000 years. Its capital, Muscat, rises gently against limestone hills with no skyscrapers to interrupt its skyline. Visitors find broad avenues lined with stunning buildings leading to landmarks like the Sultan Qaboos Grand Mosque and the Royal Opera House, both offering glimpses into Omani artistry and modern elegance.

One of San Cristobal Island's most popular visitor sites is Cerro Brujo, with its expansive white sand beach and a lagoon that locals once used as a salt mine but now offers excellent snorkeling opportunities. Another must-see is Kicker Rock, a fascinating rock formation that looks like a boot from one angle (hence its English name) and like a sleeping lion from another (thus its Spanish name, Roca León Dormido).

Denmark is almost completely surrounded by water: the North Sea to the west and the Baltic Sea to the east. It is a quaint and friendly country whose residents take great pride in their Danish culture.

Yokohama, Japan's vibrant port city, offers a delightful blend of historical charm and modern excitement. Located just a short train ride from Tokyo, Yokohama is renowned for its picturesque waterfront and cultural attractions.
