Sunset in Key West, Fla.

The best travel bargains are free. Here are five to seek out, according to a press release from TripAdvisor.com.

I’ve been to two of them (The Cliff Walk in Newport, R.I., and Griffith Observatory in Los Angeles). I’d quibble with the description of “unheralded” but agree that both are memorable destinations.

And now, a question for readers of this blog:

Trip Advisor’s Top 5 Free Unheralded U.S. Attractions

1. Spectacular Sunset: Mallory Square, Key West, Florida
Local artisans, food vendors, street performers, and tourists gather here every evening for a celebration of dazzling Key West sunsets. Revelers enjoy the entertainment of acrobats, musicians, and other performers, all while awaiting the main attraction of the evening: the setting sun’s spectacular display. According to one TripAdvisor traveler, “Of course, the best of Mallory Square is the sunset. You can’t imagine the beauty of this, it is just awesome.”

2. Sandstone Sensation: Garden of the Gods, Colorado Springs, Colorado
Its name does not overstate the beauty and the scale of this impressive sight. The Garden of the Gods is home to some of the most uniquely beautiful sandstone rock formations in the country, and affords incredible views of Colorado’s famous Pike’s Peak mountain behind the stunning red giants of the park. According to one TripAdvisor traveler, “Beautiful and right near the city, it’s free. Be sure to look for the ‘kissing camels’ (two rocks that resemble camel heads kissing).”

3. Breakers’ Best: Cliff Walk, Newport, Rhode Island
Newport’s lovely three-and-a-half mile scenic Cliff Walk gives a serene and striking view of the Atlantic Ocean and of the famous Newport mansions that overlook it. Just away from the bustle of downtown Newport, Cliff Walk is a New England treasure that doesn’t cost a dime. One TripAdvisor traveler said, “We’ve been doing the hike for decades and it always seems new and fresh….Seeing the water on one side and the huge looming mansions on the other is an incredible experience.”

4. Night Sky Delight: Griffith Observatory, Los Angeles, California
Visitors can marvel at the night sky through the observatory’s telescopes, or can simply enjoy the jaw-dropping view of Los Angeles and the Hollywood sign from Griffith’s perch more than 1,100 feet above sea level on Mount Hollywood. The observatory also houses fascinating exhibits and massive, awe-inspiring celestial murals. According to one TripAdvisor traveler, “The observatory really shines after dark, when you can observe the heavens from the 12-inch rooftop telescope.”

5. Furry Friends: Best Friends Animal Sanctuary, Kanab, Utah
Set on 33,000 acres in Utah’s peaceful Angel Canyon, Best Friends Animal Sanctuary welcomes visitors to take a free tour of its vast grounds, or volunteer to help the animals the Sanctuary protects. Travelers rave about the amazing combination of beautiful surroundings and incredible experience of helping the approximately 1,700 animals that call Best Friends home. One TripAdvisor traveler said, “The work they do is amazing, the scenery is beautiful, and I guarantee you will fall in love with at least one animal and want to take it home with you!”
