📌 Must-Read Before You Go | Key Info for 2026
⏰ Best Season: May to September is the best time to visit the South Coast waterfalls—good road conditions, long daylight hours, and abundant water flow. Some roads may be icy and trails closed in winter.
🎫 Admission: Gullfoss, Seljalandsfoss, and Skógafoss are all free to visit.
🚗 Transportation: The South Coast waterfalls are located along the Ring Road; self-driving is the best way to explore. Starting from Reykjavík, drive east along the Ring Road to visit them in order. It’s recommended to rent a 4WD SUV as Iceland’s weather is unpredictable, and 4WD handles gravel roads and sudden weather changes better.
🧥 What to Wear: Water mist from the waterfalls is heavy, so waterproof jackets, pants, and non-slip hiking shoes are essential. Cameras and phones should be protected with waterproof bags. Iceland’s weather changes quickly, so even in summer, bring windproof and warm layers.
🌊 Gullfoss | Iceland’s Most Majestic Waterfall
Gullfoss is Iceland’s second-largest waterfall and one of the three main attractions of the Golden Circle, marked as “most recommended” in travel notes. The Hvítá River, originating from Langjökull Glacier, cascades down in two tiers here, with a total drop of 32 meters. In summer, the water flow can reach 140 cubic meters per second. On sunny days, a rainbow almost always spans the mist.
· Location: About 1.5 hours’ drive from Reykjavík
· Opening Hours: Open 24 hours year-round
· Admission: Free
· Tips: Spend 45 minutes to 1 hour here. The upper parking lot offers a panoramic view from above. Roads may be icy in winter, so watch your step.
💧 Seljalandsfoss | Walk Behind the Water Curtain
Seljalandsfoss is about 60 meters high and located beside the Ring Road on the South Coast. Its biggest feature is a trail that leads behind the waterfall, allowing you to look out from inside the water curtain, like stepping into a “water curtain cave.” The trail is slippery and muddy, with heavy mist, so expect to get wet.
· Location: Beside the Ring Road, about 2 hours’ drive from Reykjavík
· Opening Hours: Open 24 hours year-round
· Admission: Free
· Tips: Spend 45 minutes to 1 hour. The classic photo spot is behind the waterfall, but the trail is slippery—wear non-slip shoes. The trail may be closed in winter; do not risk entering.
🤫 Secret Waterfall | A Hidden Gem in the Rock Crevice
The Secret Waterfall is less than a kilometer east of Seljalandsfoss, about 40 meters high, hidden inside a canyon. You need to step on stones and pass through a narrow rock crevice to enter. Many visitors leave after Seljalandsfoss, missing this hidden treasure.
· Location: Shares the parking lot with Seljalandsfoss, just a few minutes’ walk
· Opening Hours: Open 24 hours year-round
· Admission: Free
· Tips: Spend 20-30 minutes. The canyon’s mysterious lighting is perfect for dramatic photos. Stones are slippery, so walk carefully.
⚡️ Skógafoss | The Instagrammable Waterfall with a Permanent Rainbow
Skógafoss is 60 meters high and 25 meters wide, with a broad water curtain. On sunny days, a rainbow appears almost 100% of the time, making it one of the most photogenic waterfalls on the South Coast. There are stairs on the right side to climb to the top, offering a breathtaking view of the coastline.
· Location: Beside the Ring Road, about 30 minutes’ drive east of Seljalandsfoss
