# Needles Highway: A Must-Drive Masterpiece in the Black Hills
Buckle up for 22 kilometers of pure scenic magic winding through South Dakota's stunning Black Hills. This isn't just any highway—it's a 1922 engineering marvel that still feels ahead of its time, dreamed up by state highway engineer Scovel Johnson, who was determined to create something that could rival the country's most famous national park drives.
What makes Needles Highway absolutely wild is the dramatic granite spires—the "needles" themselves—that tower alongside you as you navigate some seriously tight curves. You'll encounter jaw-dropping pigtail bridges (those spiral overpasses that cleverly gain elevation in tight spaces) and tunnels carved right through solid rock that are almost claustrophobically narrow. The showstopper? The Needles Eye Tunnel, where you're barely squeezing through at 2.4 meters wide and 3.7 meters tall. Fair warning: if you're driving anything larger than a standard car, this road isn't your friend.
The Cathedral Spires dominating the landscape have earned this area serious bragging rights as a world-class rock climbing hotspot, and the road threads right past them for maximum drama. Continue into Custer State Park and you'll spot around 1,300 free-roaming bison casually hanging out in their natural habitat.

Driving Tips
# Road Trip Tips for the Area
**Size Matters for Tunnels**
If your vehicle is wider than 2.4 meters or taller than 3.4 meters, you won't be able to squeeze through the tunnels here. Worth checking before you head out!
**Be Courteous at Tunnel Entrances**
Pull over to let oncoming traffic through at the tunnel entrances. It keeps things flowing smoothly for everyone.
**Make It a Full Day**
This drive pairs beautifully with Iron Mountain Road and Wildlife Loop Road. String them together and you've got yourself an amazing scenic day out.
**Watch Out for Bison**
Custer State Park is home to bison, and they don't always stick to the side of the road. Keep your eyes open and be ready to slow down or stop.
**Budget for Entry**
You'll need to pay a park entrance fee to get in, so have that ready when you arrive.

moderateIs there a road to Oak Island?
🇨🇦 Canada
Ever dreamt of hunting for buried treasure? Head to Oak Island on Nova Scotia's south shore – you know, the place from "The Curse of Oak Island"! Getting there is part of the adventure: you'll cross a 200-meter causeway connecting the island to Crandall's Point. It's the only way on or off the island. Built back in '65 to haul in excavation equipment, this little land bridge is how you get to explore this mysterious place. Just remember, you can only visit on pre-booked guided tours, so plan ahead. While you're on the island, you might stumble across chained-off areas marked "Private/No Hunting or Trespassing/Danger," so keep an eye out. Get ready for a treasure hunt of your own!
hardMiller Lake
🇺🇸 Usa
Alright, adventure seekers, listen up! Wanna tackle one of Utah's highest roads? Head to Wayne County and find Miller Lake, perched way up in the Boulder Mountains at a staggering 10,652 feet! This isn't your Sunday drive, folks. Forest Road 544 is a rough and ready gravel track with hairpin turns that'll test your skills. We're talking rocky challenges and potential for sudden loose gravel, so a 4x4 isn't just recommended—it's essential. But here's the payoff: unbelievably fantastic scenery and access to some seriously epic hiking and fishing. Just remember, this road's a beast. Winter snow can make it impassable, and even a little rain turns it into a slippery mess. Be prepared for anything – even winter weather in summer! Pack your gear, check the forecast, and get ready for a ride you won't forget!
hardWhy is it called Tejon?
🇺🇸 Usa
Okay, picture this: you're cruising along Interstate 5 in California, headed toward Tejon Pass. This isn't just any highway; it's a 76-mile stretch connecting the Central Valley to Southern California, and it climbs to a whopping 4,160 feet above sea level! Locals often call it the Grapevine, but that's technically just a super steep 5-mile section with a 6% grade. The whole pass is a gradual climb from the south, but the north side? Get ready for a wild descent! Northbound drivers drop over 2,600 feet in just 11 miles, with some seriously steep sections. Southbound, you'll tackle rolling hills before plunging down a "5-mile grade" that loses over 1,600 feet. Heads up, truckers: there are a couple of runaway truck ramps near the top—this road means business! And speaking of business, winter here can be brutal. This area's known for sudden weather changes, and heavy snowfall can shut the whole thing down. Icy conditions on those steep grades with holiday traffic? No thanks! But when the sun's out, the views are killer, offering a gateway from the hustle of Los Angeles to the rest of California. Just remember to respect the road, and maybe say a little thank you to Lt. Francisco Ruiz, who named it after spotting a dead badger here way back in 1806!
hardWhere is Gates Pass?
🇺🇸 Usa
Cruising west of Tucson, Arizona? You NEED to hit Gates Pass! This scenic route punches right through the Tucson Mountains at a lofty 3,179 feet. Built way back in 1883 and named after local legend Thomas Gates, it's a local fave for good reason. Clocking in at just under 5 miles, Gates Pass Road connects Tucson to Kinney Road. But don't let the short distance fool you! This drive is an experience. Be warned: it's narrow, winding, and steep, with gradients hitting a max of 13% in spots! You're hugging the edge of the mountain, so keep your eyes on the road. Big rigs (over 40-50 feet) aren't allowed, and some folks prefer the Ajo Road route to avoid the thrills. But oh, those views! Gates Pass is famous for its breathtaking desert scenery. Picture saguaros dotting the slopes and panoramic vistas stretching as far as the eye can see. And the sunsets? Legendary! Pack your camera, find a scenic overlook, and prepare to be amazed. It's the perfect spot to watch the sun dip below the horizon or catch a summer thunderstorm rolling across the valley. Trust me, Gates Pass is worth every twist and turn!
