Playa del Carmen, Mexico
Playa del Carmen is a fun place to spend a long weekend if you're craving a fall getaway destination that excels both in natural beauty and nightlife. Around 35 miles south of Cancun International Airport, Playa del Carmen is home to a main drag known as Fifth Avenue, beautiful white sand beaches and affordable lodging options.

What's more, during fall this beach destination sees fewer crowds and hotels offer cheaper rates. In fact, nightly rates for Playa del Carmen hotels with double occupancy start at less than $75 per night (including taxes and fees) over dates in October this year.

Sedona, Arizona
Red Rock Country is surrounded by more than 1.8 million acres of national forest along with towering cliffs and multihued stone formations. Sedona is perfect if you're seeking fall destinations for hiking, biking and exploration. Visit this rugged but exceptionally beautiful town for outdoor recreation at one of its state parks and shop for local souvenirs at the Tlaquepaque Arts & Shopping Village.

Don't forget to book one of the Pink Jeep Tours the area is known for. These excursions take you out in the countryside and mountains, affording incredible views of the area's glorious peaks and red rocks.

The Great Barrier Reef
One of the best vacation ideas is to visit the world's largest coral reef in the Pacific Ocean, off the northeastern coast of Australia. It's always warm, so you can admire the stunning underwater world at any time of year. In spring and summer, large sea turtles come to the coast, and from November to May, the poisonous jellyfish spawn, when you can dive but only in a wetsuit. Delightful impressions of such an underwater walk will last long. You can not see such beauty on any, even the most popular, diving resorts. You don't even need to dive to see it. You can admire the motley inhabitants and stunningly bright colors of the Great Barrier Reef from special floating platforms with a transparent bottom.

Acadia National Park, Maine
Venture up north and spend a crisp fall day hiking in Acadia National Park. Not only does it boast some incredible views of Maine's coastline, but it also features a vibrant array of fall foliage in nearly every color imaginable.
