South Coast and Hot Springs in One Day: The New Tour That Ends in a Lagoon

Iceland is not short of geothermal lagoons, and it is certainly not short of South Coast day tours. Putting the two into one day, in the right order, is rarer.

On South Coast Wonders with Reykjaböð Hot Springs, you spend the day on the classic South Coast run, and instead of being dropped back in the city with tired legs and a long evening ahead, you finish the day in warm water at Reykjaböð, the geothermal lagoon that opened at the mouth of Reykjadalur valley on 1 September 2026. It is the first of our South Coast tours to build a lagoon into the tour itself.

It sounds like a small change to the schedule. It makes a considerable difference to how the day feels.

Fitting Iceland's South Coast and a geothermal lagoon into the same day usually means either two separate days or a lot of doubling back. This tour does both in one run from Reykjavík.

Here is the shape of the day:

• Departure from BSÍ Bus Terminal in Reykjavík at 09:00
• Seljalandsfoss, Skógafoss, Sólheimajökull, Reynisfjara black sand beach and the village of Vík, with a guide
• Drop-off at Reykjaböð Hot Springs in Hveragerði in the late afternoon
• Return transfer to Reykjavík at 21:00
• Roughly 13 hours door to door, all year, rated easy

Admission to Reykjaböð and a towel are included, so there is nothing extra to book and nothing extra to carry. The tour is operated by Reykjavik Excursions. You can see dates and book it here.

This is the genuinely interesting part, and it comes down to a map.

Iceland's two best-known lagoons both sit west of Reykjavík. The Blue Lagoon is out on the Reykjanes peninsula, near the airport. Sky Lagoon is on the Kársnes shoreline in Kópavogur, on the edge of the capital. The South Coast, meanwhile, runs east.

That geography is why a South Coast day and a lagoon have rarely sat comfortably together. Finishing the coast at a lagoon on the far side of the capital means driving back past your hotel, soaking, then driving out again — more time on a coach at the end of an already long day.

Reykjaböð changes the maths. It sits in Hveragerði, about 35 minutes from Reykjavík, at the entrance to the Reykjadalur valley — directly on Route 1, the road the coach is already taking home. The lagoon is not a detour. It is on the road you were already taking home.

That single fact is what makes a 13-hour day feel civilised rather than punishing. You are not adding a journey. You are adding a stop to one you were making anyway.

The sightseeing half of the day is the South Coast itinerary Icelandic guides have been running for decades, and it earns its reputation. Five stops, and no two of them alike.

Seljalandsfoss

The first waterfall of the day and the one people photograph most. Seljalandsfoss drops around 60 metres off an old sea cliff, and a footpath runs all the way behind the curtain of water — the only major waterfall in Iceland where you can do that. Expect to get damp. That is rather the point.

Skógafoss

A short drive further east, Skógafoss is the opposite kind of waterfall: broad, heavy and loud, thundering off a cliff that once marked Iceland's coastline. Centuries of lava flow and erosion have since pushed the sea back several kilometres. Climb the staircase beside it and you can still pick out the grey Atlantic in the distance.

Sólheimajökull

Between the waterfalls and the coast, the road turns inland to Sólheimajökull, an outlet glacier spilling off the Mýrdalsjökull ice cap. It is one of the most accessible glacier snouts in the country, and one of the clearest places to see what a warming climate looks like up close: the ice has withdrawn visibly within living memory, and a meltwater lagoon has opened at its foot as it has gone. The tour takes you to the base camp at the edge of the ice. Walking out onto the glacier itself is a separate guided activity, with crampons and a certified guide.

Reynisfjara

Then the coast itself. Reynisfjara is jet-black volcanic sand, hexagonal basalt columns stacked like organ pipes, and the Reynisdrangar sea stacks offshore. It is also genuinely dangerous: the sneaker waves here arrive without warning and have killed visitors. Your guide will tell you where the line is. Stay behind it, and stay facing the sea.

Vík

The day's furthest point is Vík, Iceland's southernmost village and the only settlement of any size along this stretch of coast. Barely three hundred people live here, under the Reynisfjall cliff and in the shadow of the Katla volcano, with the Reynisdrangar stacks standing offshore. It is the natural place to pause for something hot before the coach turns back west.

By the time the coach pulls into Hveragerði you will have been on your feet in Icelandic weather for most of the day. This is where the tour stops being a sightseeing trip and starts being a recovery.

Reykjaböð is built around a 900 m² geothermal lagoon held at 38–40°C, with varying depths so you can find your own corner of it. Around that sits an outdoor ritual circuit: an event sauna, cold plunge pools and a Kneipp pool for walking hot-and-cold through the water. Moving between the heat and the cold is the whole idea — it is a Nordic bathing tradition, not a gimmick, and it does remarkable things for legs that have spent nine hours on gravel paths. We have written a full guide to Reykjaböð if you want the detail on the facilities.

Your tour ticket covers admission, the outdoor ritual area, the sauna, cold plunge and Kneipp pool, changing facilities and a towel. Food and drink are not included, but there is a bistro on site and a bar you can reach without leaving the water, so bring a card.

What makes the timing work in your favour is the hour. You arrive in the late afternoon and stay until 21:00, which in winter means you are in the water after dark, steam rising off the surface, with a decent chance of the northern lights over the valley. In summer it means a long, bright Icelandic evening that never quite ends.

The tour departs from BSÍ Bus Terminal in central Reykjavík at 09:00. Pickup from designated bus stops is available, which means you can be collected near your accommodation rather than making your own way across town at dawn.

From there it is roughly two hours east to the first waterfall, with a refreshment stop on the way. The South Coast stops fill the middle of the day, with time at each rather than a race between them. From Vík, the furthest point, the coach turns back west in the late afternoon and drops you at Reykjaböð.

Your return transfer leaves Reykjaböð at 21:00, putting you back in Reykjavík at around 22:00. Thirteen hours in total.

There is a live guide in English throughout, plus an audio guide you can run on your own phone in French, Chinese, Korean, German, Italian, Dutch, Finnish, English, Japanese and Spanish. Bring headphones if you plan to use it. There is free Wi-Fi on board.

Thirteen hours is a long day, and we would rather you picked the right tour than the biggest one. Here is the honest version.

Book this one if

• You have limited days in Iceland and want the South Coast and a lagoon without spending two of them
• You are travelling without a car and want the whole thing solved in one booking
• You like the idea of finishing a hard day of sightseeing in hot water rather than in a hotel room
• You are visiting in winter and want a realistic shot at northern lights over a steaming lagoon

Book something else if

• You are travelling with young children or anyone who tires easily. The shorter South Coast Wonders tour covers the same coastline and gets you home earlier
• You only want the lagoon. The Classic Admission with transfer is a straightforward 4.5-hour round trip from Reykjavík
• You want the full Bathhouse Spa with its ten sensory spaces, which is the Signature Admission experience rather than what is bundled into this tour
• You are lagoon-shopping more broadly: our guide to the best hot springs in Iceland compares the options

The two halves of this day ask for different things, and the trick is packing for both without hauling a suitcase around a black sand beach.

• Warm layers, a waterproof jacket and sturdy waterproof boots — Seljalandsfoss will soak you and Reynisfjara is exposed
• Hat, gloves and warm socks from roughly October to April
• A swimsuit. The towel is included, the swimsuit is not
• A small bag for wet swimwear on the ride home
• Snacks, a water bottle, and a card for the bistro and bar at Reykjaböð
• Headphones, if you want the audio guide in your own language

Leave the good camera in the daypack at Reynisfjara if the sea is up. Salt spray and wind-driven black sand are not kind to lenses.
