Banff National Park in Alberta, Canada, was created in 1885 as the world's third national park. It is deeply tied to Canada's natural history.
"The uniqueness is … the wildlife, the fact that it's a pristine national park," said David Roberts a vice president of Alberta Fairmont Hotels. "What you see today is here for the next 100 or so years."
The park boasts a complex and unique ecosystem.
"Every animal in the park has an important," said Daymon Miller of Discover Banff tours. "It's kind of like a jigsaw puzzle: It all fits together and if you take out a piece it has an effect. … Wolves are dependent on the elk population. All of these things are connected together. If one of these things are lacking, it has an effect on everything else."
The Golden Islands are barrier islands off the coast of Georgia that are characterized by 17.5 miles of undeveloped beaches, oak trees and wild horses. They are also a birder's paradise, according to Carey Ferrara of the Georgia Department of economic development.
"We have osprey that nest on the island," he said. "We have wood stork, an endangered species, here on the island."
The island is also a favorite place among America royalty. JFK Jr. was married at the First African Baptist Church on Cumberland Island. The Greyfield Inn on the island is run by descendants of the Carnegie family.
"The coast of Georgia is just a diamond in the rough," said Tim Matthews a business owner on St. Simons Island. "It's got a great coastline. You are the farthest point west on the East Coast. You have calm waters and calm weather."
Springtime in the nation's capital is synonymous with cherry trees. There are more than 3,750 cherry trees that are set to blossom in Washington, D.C. The trees were a diplomatic gift from the people of Japan and include 12 different varieties. The most common is the Yochino cherry.
"All of that combination together sort of creates this very pink cloud that almost hangs over the Tidal Basin that is just magical to be a part of," said Diana Mayhew, the executive director of the National Cherry Blossom Festival.
The Cherry Blossom festival is a signature springtime event in Washington, D.C. It draws about one million tourists and residents to the city over the festival's two-week period.
It's just off the coast of Los Angeles, yet miles away: Catalina Island looks much like California did 200 years ago -- a wilderness of oak, cactus, and sage, with secluded coves surrounded by ocean with lush kelp forests and abundant sea life.
Among Santa Catalina Island's greatest natural blessings are its rugged, sinuous shoreline and the crystal-clear waters that encircle the island. The island is about 58,000 acres with 58 miles of shore line.
In this wild kingdom, animals abound. Expect to see the Catalina Island fox, a sub species of the mainland grey fox, and buffalos grazing.
There was no "Weekend Window" today because "Good Morning America Weekend Edition" was broadcast live in New Orleans in honor of Mardi Gras.
Padre Island National Seashore on Texas' Gulf Coast is famous for spring break partying. But it is also a good place to get away from it all. It is the world's longest barrier island and is 113 miles from the top to the bottom. Seventy of those miles are protected and will stay undeveloped.
