# Needles Eye: A Granite Adventure in South Dakota
Want to experience one of South Dakota's most unforgettable drives? Head to Custer County and tackle Needles Highway—a stunning 14-mile stretch of scenic road that winds through the Black Hills' iconic granite formations. This section of Highway 87 is part of the Peter Norbeck Scenic Byway, and it's absolutely worth the detour.
The main attraction? The Needles Eye tunnel itself, a one-lane passage carved straight through solid granite with dimensions of just 8 feet 4 inches wide by 12 feet high. It's genuinely the narrowest tunnel in South Dakota, making it equal parts thrilling and claustrophobic (though totally manageable if you're not severely phobic). You'll share the road with other tourists and the occasional charter bus, so confidence in your vehicle's size is key. RV and large trailer owners? This might not be your jam. For details on tunnel specs and current conditions, swing by the visitor center.
Fair warning: this isn't a speedy drive. Budget 45 minutes to over an hour for the full journey—and honestly, you'll probably find yourself crawling along at 20 mph just to soak in the scenery. The narrow, winding road with hairpin turns and granite needle formations means you'll want to pause frequently at pullouts rather than rush through. The asphalt is well-maintained, and nearly all traffic consists of leisurely sightseers.
Nestled in Custer State Park, this road was meticulously planned by former Governor Peter Norbeck, who actually mapped the entire route on foot and horseback. It was finished in 1922, and it's been drawing visitors ever since.
Keep in mind: the road typically closes from mid-October through early April due to snow, so plan your visit for warmer months. There's an entrance fee for the park, but trust us—it's worth every penny.

hardCostilla Pass
🇺🇸 Usa
Okay, adventure seekers, listen up! Costilla Pass in New Mexico's Colfax County is calling your name. We're talking a sky-high climb to 9,770 feet in the rugged Sangre de Cristo Mountains. Now, this isn't your Sunday drive. The road? Let's just say "character-building." Expect a rough, bumpy, and tippy ride that demands respect. And forget about it in the winter—this pass stays snowed in, often until well into summer. Experienced off-roaders, this one's for you! The trail is narrow, making passing tricky, and it's seriously steep. High clearance is an absolute must—leave the low riders at home. But the views? Oh man, the views are worth every bump and scrape. Get ready for some seriously epic scenery.

🇺🇸 Usa
Okay, so you're looking for an epic Wyoming adventure? Check out Brooklyn Lake! Nestled high in Carbon County, at a whopping 10,639 feet, this alpine lake is seriously gorgeous. Getting there is part of the fun! You'll be cruising on Forest Road 317 (aka Brooklyn Lake Road), a gravel road that's a bit rocky and bumpy, so be prepared for a "tippy" ride. Think of it as adding character! A high-clearance 2WD vehicle is ideal. The road is generally closed from September to June due to snow, so plan accordingly. Once you reach the lake, you'll find a spacious parking area and some incredible views. This area is a maintained road and an amazing destination for anyone who loves hitting the trails. If unpaved mountain roads aren't your thing, maybe sit this one out. But if you're an experienced off-roader looking for a great adventure, Brooklyn Lake Road is calling your name!

hardCarr Canyon Road in Arizona: narrow and steep with no guard rails
🇺🇸 Usa
Okay, adventure time! Let's talk about Carr Canyon Road #368 in Cochise County, Arizona. This isn't just any road, it's a historic mining route revamped by the CCC back in the day. Picture this: you're in the southeast corner of Arizona, deep in the Coronado National Forest, ready to tackle 7.8 miles of winding road up the Huachuca Mountains. You'll start on some pavement, but soon you'll be kicking up dust on a dirt road that's mostly good for regular cars. Now, this isn't a Sunday drive. Get ready for narrow sections, hairpin turns that'll have you gripping the wheel, and steep climbs that'll make your engine work. Oh, and did I mention no guardrails? Adds to the thrill, right? If you're rolling in something massive (over 20 feet long) or towing a big trailer (over 12 feet), you'll have to stop at the Carr Canyon Picnic Area. Give yourself about 40 minutes to cruise this road, but trust me, you'll want to stop. This is the only way to get to the top of the Huachuca Range. Pull over at the overlooks, because the views of Sierra Vista, the San Pedro Valley, and all those surrounding mountains are unreal. Up top, you'll find a basic campground and tons of hiking trails. Heads up: this road usually closes for the winter (mid-December to mid-March). The climb is no joke, hitting a max grade of 12% in spots! You'll gain over 2,500 feet from the start, averaging around a 6% grade. Get ready for an epic climb and unforgettable views!
