Glymur Waterfall in Iceland: Hiking Trail, Parking and Self-Drive Guide 

To hike to impressive Glymur Waterfall, you must drive to the Botnsá parking lot at the end of Route 47 in West Iceland and conquer a 7.5-kilometre round-trip trail. Safely completing this difficult, three-to-four-hour trek requires crossing the rushing Botnsá River via a narrow wooden log equipped with a safety cable, which is only installed seasonally from June to early September. This self-drive guide provides the exact driving times, packing essentials, and river-crossing safety rules you need to experience one of the country’s most dramatic geological wonders. 

Is Glymur Waterfall Worth the Hike?

A journey to this dramatic canyon ranks among the most rewarding and visually spectacular outdoor experiences in the entire country. Many tourists rush along the main highways of the Ring Road without realising they are bypassing a majestic geological masterpiece. Unlike other easily accessible cascades across the south and west of the island, where you can simply park your vehicle, step out, and take photos from a designated viewing platform, this giant requires physical effort and a spirit of adventure. 

The trek to reach the falls takes you through stunning basalt formations, historic caves, and narrow pathways that showcase the raw, untamed power of Icelandic nature. Walking through this wilderness allows you to experience the authentic wild spirit of the island up close. Planning an independent road trip gives you the ultimate freedom to explore these hidden gems at your own pace, ensuring that you do not miss the stunning Glymur waterfall while setting an itinerary that matches your personal comfort level.

Height, Canyon Views and What Makes the Trail Unique 

Standing at an impressive height of 198 meters (650 feet), the majestic Glymur waterfall held the title of Iceland’s tallest waterfall for decades. Although geologists recently discovered a taller cascade hidden near a glacier, this legendary giant remains the most striking, dramatic, and accessible high waterfall in the country. The hiking trail snakes along the edge of a deep, mossy canyon carved over millennia by the roaring Botnsá River. 

As you ascend the steep cliffside, you will witness the heavy glacial water plunging into the dark abyss while arctic fulmars glide gracefully through the rising mist below. This unique trail combines geological wonders with a sense of pure adventure that you cannot find on standard tourist routes. Winding along the edge of this deep, vertical canyon provides an unforgettable perspective of the surrounding valley, where vibrant green moss contrasts beautifully against the dark, volcanic basalt. 

How to Get to the Glymur Trailhead by Car 

Navigating the scenic roads of West Iceland offers a liberating travel experience that only a car can provide. To reach the trailhead, you will drive through some of the country’s most historically significant coastal landscapes, passing peaceful farms and rugged mountain ranges. Safe driving protocols, speed limit laws, and critical route awareness are vital to keep self-driving travellers safe across the island. 

The journey to the trailhead allows you to experience the dramatic western fjords without rush, giving you the freedom to stop at scenic coastal viewpoints whenever you wish. A high-quality rental vehicle ensures a seamless transition from smooth, paved highways to the rustic gravel pathways that lead directly to the spectacular trailhead. 

Beyond the waterfall itself, the scenic drive along Hvalfjörður is a massive highlight of your road trip. Choosing to skip the undersea tunnel and take the historical Route 47 allows you to navigate a tranquil, 30-kilometre winding shoreline framed by dramatic, towering mountains. Historically, this deep fjord served as a vital naval base during World War II, and travellers can still spot the ruins of an old whaling station along the coast.  

Driving your vehicle at a slow, steady pace gives you the ultimate freedom to pull over at quiet coastal viewpoints to photograph the local birdlife or watch for seals playing in the calm waters. This spectacular approach builds the excitement for your Glymur waterfall hike and transforms a standard day trip from Reykjavík into an immersive, unforgettable journey through West Iceland’s historical landscapes. Always check road conditions before leaving, especially during winter months when coastal crosswinds can be extremely powerful.

Hiking Route Map

Distance, Difficulty, River Crossing, Cave Section and Safety 

The total length of the Glymur waterfall trail loop measures approximately 7.5 kilometres (4.7 miles) and requires three to four hours to complete. Hikers classify the trail as moderate to difficult due to the steep elevations, narrow paths, and loose volcanic gravel. Early in the hike, you will pass through a small lava cave called Þröng Jóru, which offers a unique, dark passage opening directly onto the riverbank. Soon after, you will reach the first major obstacle: the lower river crossing. From June to early September, search and rescue teams install a wooden log with a safety cable across the Botnsá River. You must walk carefully across this log to continue on the main trail. 

For a safe hike, please follow these essential rules: 

• Check water levels: Never attempt to cross the river if high water submerges the log. 
• Use the safety cable: Hold onto the installed metal wire with both hands while crossing the log. 
• Stay on marked paths: Do not step off the trail to avoid damaging the fragile, slow-growing arctic moss. 
• Never attempt to cross the cold river on foot during winter: The log is removed in autumn, and crossing without it is highly hazardous. 

Respect your limits:  Turn back if you experience vertigo on the high cliffside sections. For more information on navigating these conditions, visit the Hertz Iceland safety portal. 

Glymur Parking and What to Bring 

Proper preparation makes the difference between an unforgettable adventure and a cold, wet ordeal. The trailhead features a dedicated gravel parking lot officially labelled as Botnsá on digital maps. Parking at this location is free of charge, but the lot fills up rapidly during peak summer months. We highly recommend arriving before 9:00 AM to secure a spot and enjoy the peaceful morning air on the trail. 

Note that this remote parking area does not provide restroom facilities or trash cans, so you must plan accordingly before leaving your accommodation. Having your own rental car parked nearby gives you a convenient space to change clothes, dry off, and store extra gear before and after tackling the challenging Glymur waterfall hike. 

Footwear, Layers, Water, Snacks and Hiking Prep 

To enjoy your journey safely, you must pack appropriate gear for the highly unpredictable Icelandic climate. Start with a sturdy pair of waterproof hiking boots that offer deep tread and ankle support. The rocky terrain, loose volcanic gravel, and wet riverbanks require exceptional traction to prevent slips. Wear a moisture-wicking base layer, followed by a warm fleece or wool mid-layer, and a windproof, waterproof outer shell jacket to protect against sudden rain. 

You should also pack lightweight water shoes and a small quick-dry towel if you plan to tackle the second river crossing at the top of the canyon, where wading through the cold water is required to complete the loop. Carry a small backpack stocked with a reusable water bottle, energy-dense snacks, and a fully charged mobile phone. 

Additionally, weather conditions in West Iceland can change in a matter of minutes. Trekking poles can save your knees on the steep descent, where loose gravel often makes the path slippery. If you plan to take high-quality photographs of the canyon, bring a protective waterproof sleeve to guard your camera against the constant mist drifting from the Glymur waterfall. Always inform someone of your travel plans before setting off. Being thoroughly prepared guarantees that you can focus entirely on the jaw-dropping scenery instead of battling the elements. 

Best Rental Car for Visiting Glymur 

Choosing the correct vehicle for your trip ensures a safe, comfortable, and stress-free journey through the fjord. If you are travelling with family or carrying multiple suitcases, booking a spacious family-friendly rental car in Iceland is the perfect starting point to guarantee optimal passenger comfort on your western journey. 

• Summer Travellers (June to September): If you limit your summer itinerary strictly to the paved Route 47 and the short gravel access road, a standard 2WD economy car, compact hatchback, or fuel-efficient sedan will suit your needs perfectly. These smaller vehicles offer excellent fuel economy and are easy to park at Botnsá. 
• Highland & Rough Road Explorers: For travellers who want extra durability and comfort on gravel tracks, or who plan to tackle the rugged side roads of West Iceland, renting a robust 4×4 for Iceland roads is highly recommended. It offers the high ground clearance and all-wheel-drive traction needed to safely handle sudden potholes. 
• Winter and Shoulder Seasons (October to May): During the colder months, unpredictable snowstorms, black ice, and powerful crosswinds make a robust 4×4 SUV equipped with high-quality winter tyres absolutely mandatory. A heavier, stable all-wheel-drive system gives you the confidence to navigate the exposed coastal highways safely.
