Redwood National and State Parks protect a remarkable coastal landscape in northern California, where ancient redwood forests grow alongside rivers, prairies, wetlands, and the Pacific Ocean. The protected area extends across a series of parks in Del Norte and Humboldt counties, preserving some of the tallest trees on Earth. Dense stands of coast redwoods create shaded forest environments beneath a canopy of towering trunks, while nearby coastal bluffs and beaches provide a striking contrast.

Gulfport, Mississippi, is the largest city on the Mississippi Gulf Coast and an important center for beaches, fishing, shipping, and coastal recreation. The city faces the Mississippi Sound, with barrier islands lying offshore and helping shape its relatively calm coastal waters. Gulfport Beach stretches along the shoreline with wide sandy areas, while the Port of Gulfport serves as a major deep-water shipping facility.

What sets Kaikōura apart are the extraordinary marine encounters that begin just off the shoreline. The Kaikōura Canyon, an underwater gorge that plunges to great depths close to land, creates currents rich with nutrients that attract a remarkable array of sea life year-round. Sperm whales are a common sight here and are frequently spotted on local boat tours. Dusky dolphins twist and leap in large pods, and colonies of New Zealand fur seals laze on rocky outcrops along the coast.

A Caribbean island paradise, Cozumel lies a short distance from Mexico's Yucatán Peninsula. Visitors can enjoy a variety of activities, whether taking advantage of world-class snorkeling and scuba diving, swimming with dolphins, or lounging with a drink at one of the island's seaside resorts.

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).
