Once an important center for sugar production, Puerto Rico's fourth largest city's current fortunes come from its factories. Intriguing nicknames for the city of nearly 200,000 include The Land of Giants and Arm Hackers Town. Situated on the island's north shore, this Atlantic city is considered part of the metropolitan San Juan area. Popular attractions include Carolina Beach, Casa Escute art gallery, Caribbean Raceway Park and Isla Verde Mall. To make the most of your visit, consider renting a car.

This resort area on the southern part of Gran Canaria has a laid-back, upscale vibe. You’ll find crystal-clear water perfect for snorkeling, a network of canals (which gave the town the nickname “Little Venice”), and a number of restaurants and bars along the pretty beach.

"Playa Blanca" means "white beach," and indeed, travelers flock here to swim and sunbathe. Huge yachts bob up and down at the marina, where you'll also find many shops and restaurants and a lively market. TripAdvisor travelers say Montana Roja is not "particularly strenuous" and offers amazing views from the top.
