A round-trip cruise with KD is one of the best ways to take in Frankfurt’s skyline from the water. The one-hour route along the Main River passes landmarks like the Römer, the Museum Embankment and St Paul’s Church, with commentary about the city’s past and present.

Saint Paul’s Church (Paulskirche) was consecrated in 1833 and hosted Germany’s first national assembly in 1848, which helped shape the country’s modern constitution. Visitors can see the historic interior and sometimes attend political or cultural events held in the building.

A 20-minute boat ride from Cancún lies the small island of Isla Mujeres with its laid-back Caribbean ambiance, tiny streets lined with stalls, and street cafés in pastel-colored houses. Golf carts and mopeds dominate the streets, and although the island is only 5 miles long and half a mile wide, it still offers plenty of things to do and see. Everything from a beautiful palm-fringed white beach on the north coast to a dramatic rocky shoreline on the eastern side to a sea turtle sanctuary and the remains of a Mayan temple at the southern tip. If you're into adventure, then you should visit the Garrafon Reef Park & Beach Club, where you can go zip-lining, snorkeling, and kayaking. Lastly, a must-visit for nature and wildlife lovers is a tour to Isla Contoy, a nature reserve only inhabited by a few biologists and restricted to 200 visitors per day.

Surrounded by water on three sides, Smyrna Dunes Park offers stunning views of the Indian River, Ponce Inlet, and the Atlantic Ocean. Arrive by land or sea to explore its fishing spots, swimming areas, and scenic trails. Keep an eye out for wildlife—birds, reptiles, marine life, and native vegetation thrive here in their natural habitats.
