The following post is an answer by Khalil Ahmad on Quora:
Here are 29 places in 20 countries from around the world that includes: United States, Norway, Canada, Ireland, China, Bolivia, South Africa, Japan, Iceland, New Zealand, Italy, Switzerland, Africa (Algeria/Niger/Nigeria), Chile, Australia, Scotland, France and India.
1. HANA HIGHWAY, HAWAII, UNITED STATES: This highway is known for its rainforests, waterfalls, and uniqueness. It’s the ideal spot for a tropical road trip.
2. OVERSEAS HIGHWAY, FLORIDA, UNITED STATES: Drive straight into the ocean. Enjoy 113 miles of nothing but sea on either side of you.
3. PACIFIC COAST HIGHWAY, CALIFORNIA, UNITED STATES: Considered the site of one of the best road trips in the U.S.
4. Atlantic Ocean Road, Norway: This 5 miles long is just about the most scenic route one could imagine. Explore a system of islands and islets … by road. This dangerous, breathtaking road is considered by some to offer the world’s most beautiful drive. Hop across tiny islands over a system of eight roller-coaster-like bridges, including the “bridge to nowhere,” which at first appears like one’s about to drive off into the ocean.
5. TROLLSTIGEN, NORWAY: Called the “Troll Ladder,” this 65.8-mile stretch contains 11 hairpin bends, which help you to manage the crazy incline of nine percent and get up to 858 meters above sea level (2,814.96 feet, which is still higher than the world’s highest skyscraper).
6. TUKTOYAKTUK WINTER ROAD, CANADA: Oh, we’ll just wait for the Arctic Ocean to freeze. It’s fine, this highway connects ice-locked communities and is mostly used by huge, heavy tractor-trailers.
7. CONNOR PASS, IRELAND: Winding through the highest mountains in Ireland and fairy-tale-like vistas on the Dingle Peninsula, this tight street also happens to be mostly one-way. It’s the most beautiful and possibly the most dangerous in Ireland.
8. GUOLIANG TUNNEL, CHINA: Drive literally through a cliff.
9. VALLEY OF FIRE ROAD, NEVADA, UNITED STATES: Deep red Aztec sandstone lines the landscape surrounding Nevada State Route 169. In the reflection of the powerful desert sun, the state park really looks like you’re driving through fire.
10. TIANMEN MOUNTAIN ROAD, CHINA: The 99 turns may be a bit much for you, but you’ll be 3,937 feet in the air when you’re done.
11. NORTH YUNGAS ROAD, BOLIVIA: On another one of the most dangerous roads, your trip across the “road of fate” or “death road” will include having a rock cliff on one side and a 2,000-foot drop on the other, and there’s severe fog occasionally.
12. SANI PASS, SOUTH AFRICA: Climb up to an altitude of 2,876 meters (9,436 feet) here. To give you some perspective, aircraft are required to have pressurized cabins at 10,000, and you’re almost there. This mostly one-lane, muddy road also is notorious for bad weather and relentless snow at that height. It’s nuts.
13. TATEYAMA KUROBE ALPINE ROUTE, JAPAN: The “great snow wall drive” will make you rethink your winter commute (and probably drool a little).
14. RED ROCK SCENIC BYWAY, ARIZONA, UNITED STATES: The strange, otherworldly rock formations are the most notable feature of this valley road, considered to be the partner road to the Valley of Fire Road 20 miles west.
15. ROUTE 1, ICELAND: Another one of the world’s best road-trip locations, the circle-shaped highway around the island of Iceland is full of glaciers, ice caves, waterfalls, and rainbows. Watch the sun set on the ocean and the mountains along the “ring road.”
16. SKIPPERS CANYON ROAD, NEW ZEALAND: The scary, beautiful, narrow, mostly one-way path over the Shotover River outside of Queenstown.
17. STELVIO PASS, ITALY: The Passo dello Stelvio allows you to zip and turn along the top of the Alps at 9,045 feet.
18. SUSTEN PASS, SWITZERLAND: With tight curves through the inner Alps, this road gives you the full view of both glaciers and idyllic valleys.
19. Trans-Sahara Highway, Africa: The 2,800-mile Trans-Sahara Highway crosses three countries (Algeria, Niger and Nigeria), on its journey through the world’s largest desert. Unsurprisingly, fuel and water are unavailable along the majority of this sun-baked stretch; and you really don’t want to run out of petrol here. If that doesn’t sound dangerous enough, it isn’t uncommon for sandstorms to move immense drifts and dunes onto the highway, blocking the route for days at a time.
20. CHESAPEAKE BAY BRIDGE/TUNNEL, VIRGINIA, UNITED STATES: Enjoy a stomach-churning 17-mile crossing over water.
21. Los Caracoles Pass, Chile: Connecting Chile with Argentina, the series of razor-sharp hairpin bends are difficult enough to negotiate in fair weather conditions, so just imagine having to make this terrifying journey and navigate these extreme inclines in a snow storm. The very thought is enough to chill you to the bone.
22. GREAT OCEAN ROAD, AUSTRALIA: Tour a southern highway that hugs the Pacific Ocean. This highway cuts through rainforests, national parks and whale lookouts.
23. A82 ROAD, SCOTLAND: The A82’s dramatic views of the Highlands can wow even the most unimpressed traveler.
24. GOING-TO-THE-SUN ROAD, MONTANA, UNITED STATES: It’s a road built almost for the sole purpose of being pretty.
25. THE SS163, ITALY: Cruise along by the villages of the Amalfi Coast. Vistas, gardens, pastel villages and turquoise waters, make this road a tourist attraction. Just take care, as it’s a winding route near cliffs.
26. DENALI HIGHWAY, ALASKA, UNITED STATES: Get unspoiled views of natural beauty.
27. CHAPMAN’S PEAK, SOUTH AFRICA: With 114 curves in five miles, this breathtaking road might make you a bit queasy as you look down the hundreds of meters at Hout Bay. Just watch out for falling rocks.
28. COL DE TURINI, FRANCE: Drive, or really tear through, France.
29. Khardung La Pass, Kashmir, India: The pass on the Ladakh Range is the gateway to the Shyok and Nubra valleys.
Edit: Some of my friends suggested few more, I’m thankful and here they’re:
A. Blue Ridge Parkway, North Carolina, UNITED STATES: As a scenic byway that sometimes traverses deep into the mountainous forests of Virginia and North Carolina, the Blue Ridge Parkway as a journey is unique.
B. Icefields Parkway, Alberta, Canada: The Icefields Parkway parallels the Continental Divide through some of the most wild and remote parts of Banff and Jasper national parks.
Thanks for reading.
