The Catamaran Hotel and Resort is located on Mission Bay. The waves of the Pacific Ocean are just 100 yards away. The Catamaran Tower commands a stunning view from the shores of La Jolla to Old Mexico and over Mission Bay to Point Loma and the spectacular San Diego skyline.

It’s California’s oldest city, the nation’s sixth largest city and is proudly regarded as “America’s Finest.” Splashed with spectacular sunny weather and countless tourist and cultural attractions, San Diego is justifiably another name for paradise.

Mission Bay is the ideal place for boating, fishing, skiing, swimming, board sailing and public recreation. There are 27 miles of sun-bleached beaches. The Catamaran Resort Hotel is on the bay and features a wide variety of boat rentals and water sport activities. The world-famous San Diego Zoo has over 3,900 animals of 800 species and is noted for its many rare and exotic species. Old Town San Diego is full of old adobes and other historic structures that blend with fine restaurants.

Seaport Village consists of more than 60 shops, boutiques and galleries where visitors can browse to their heart’s delight. Also nearby is the Gaslamp Quarter, a 16 1/2 block historic downtown district that recreates the spirit of Victorian times through the restoration of old buildings that feature antiques, crafts, arts, restaurants, shops and offices all in the authentic tradition of that era.
