Okayama Prefecture, Japan, holds a secret! Just northwest of Nariwacho Hayama in Takahashi City, you'll find Prefectural Road 300 snaking along the Shimaki River in the Wazan Gorge. But this isn't your average road trip, because here, you actually drive *through* a cave!

Hayama 2nd Tunnel isn't your typical, man-made tunnel. It's a limestone cave carved out by the Shimaki River over eons. Once much bigger, the river whittled it down, but the entrance was just begging for a road. They raised the ceiling to fit cars, and voila!

Now, a word of warning: this tunnel is SHORT (max height 2.5 meters), and NARROW. Think one car at a time, so forget about bringing your RV. Plus, it's completely unlit, so proceed with caution!

The road is paved, thankfully, but those tight squeezes and pitch-black conditions definitely add an element of adventure.

Dug out by hand about a century ago, you can still see the chisel marks in the walls. It's a seriously cool peek into the past.

Because of the narrowness and blind turns, honk your horn before entering. Definitely not suitable for larger vehicles!

This is a quiet rural road, but weekends can bring more curious visitors, so keep an eye out. You can park a car or two at the north entrance. Honestly, exploring on foot is the safest (and coolest) way to experience this incredible spot!

The road to Spanggur Gap isn’t an easy one

🇨🇳 China

Okay, adventure-seekers, let me tell you about Spanggur Gap! This high-altitude pass sits right on the border between India and China, clocking in at a whopping 14,133 feet above sea level. Fair warning: the road is completely unpaved, and you'll need a 4x4 to even think about tackling it. Seriously, leave your sedan at home. And if you're not a fan of heights, maybe skip this one – it's a steep climb! If it's wet, be prepared for some seriously muddy conditions. But hey, the views! To the east, you'll spot the stunning Spanggur Lake. Just remember, you're on the Line of Actual Control between China and India, so soak in the history and the scenery. This area saw some action in the 1962 war, so it's a place with a story. Just be prepared for a rugged, unforgettable drive!

Take the Iconic G318 and Discover Gya La Pass

🇨🇳 China

Alright, adventure junkies, listen up! If you're cruising through Tibet, you HAVE to add Gya La to your itinerary. This high-altitude pass, clocking in at a whopping 13,018 feet, sits pretty in the Shigatse area. You'll be gliding on smooth, paved roads the whole way - it's part of the famous China-Nepal Highway (aka the Friendship Highway). This isn't a Sunday drive, though! It's a long haul through some seriously remote landscapes, so pack your patience and prep well. The Gya La stretch itself is about 20.6 km of relatively flat driving between Shigatse and Qumuzong Caguo. Usually, you can hit this road year-round, but keep an eye on the weather, especially in winter. Those mountain conditions can change in a heartbeat!
