Iceland is an increasingly popular destination for short trips and long adventures alike, and it's no surprise. There's dramatic scenery, incredible wildlife and it's close to both Europe and the USA.

With a surge in tourism in recent years, some of its top attractions can be extremely busy but there's more to Iceland than the famous Golden Circle – the loop of the popular sites around Reykjavík that explores Geysir, Thingvellir National Park, and Gullfoss waterfall.

Here's where to go in Iceland when you've seen the big sights.

Located around an hour east of Akureyri in northern Iceland, Mývatn is like a microcosm of Iceland in one conveniently small area. The lake itself was formed by a series of volcanic eruptions and is a favorite spot for birdwatching.

You’ll also see Hverfjall, one of the biggest volcanic craters in the world, and snow-topped mountains in the background.

You can find evidence of Myvatn’s volcanic past by exploring the Dimmuborgir lava formations (pictured), a series of small mossy canyons. These are the home of Iceland’s infamous 13 Yule Lads, the Christmas pranksters who supposedly visit children to leave gifts or rotten potatoes.

A little further northeast (follow the signposts from Myvatn) is the Krafla area, one of Iceland's most active volcanic areas where the lava is still steaming hot after its last eruption in 1984.

End your visit to the lake area by taking a dip in Mývatn Nature Baths (pictured) – the Blue Lagoon of northern Iceland. The thermal pools here are blue with silica and are a toasty 104°F.

Grab a beer and float over to the edge of the pool where you’ll get impressive views over Mývatn lake and the surrounding landscape.

Thermal pools are common all over Iceland – ranging from bubbling holes in the ground only big enough for a dip to private serviced pools like the famous Blue Lagoon. Seljavallalaug pool is possibly the most photogenic of all the free hot pools and one of the most exciting.

A few hundred meters off the Ring Road in southern Iceland, you’ll have to park your car and carry on by foot into a mystical valley (pictured). Seljavallalaug pool is not hard to find, but with no cars or roads nearby it feels pleasingly secluded.

Built in the beginning of the 20th century to teach locals how to swim, the pool is not as warm as others, but it’s still pleasant for a dip. It’s free to use and there are some very basic changing facilities onsite. Kick off your hiking boots, take the plunge, and enjoy the view of the valley, but remember to tidy up after yourselves – the pool is kept clean and open by a team of dedicated volunteers.

Dettifoss is reportedly the most voluminous waterfall in Europe, as 264 gallons of water per second plunge over its rocky edge. The landscape around is stark and bleak, so the cascading veils of water crashing down the rocky canyon seem even more impressive.

Dettifoss is located in the Jökulsa Canyon, which is also home to two other small, though no less impressive, falls: Selfoss (pictured) and Hafragilsfoss. With 2.5 miles between the three falls you can hike around the canyon with relative ease.

The surrounding landscape is loved by hikers for the impressive geological anomalies that line its cliffs, such as the Whispering Rocks of Hljoðaklettar and the footprint of Norse god Odin's horse in the Ásbyrgi canyon.

The southernmost settlement on Iceland’s main island, Vík is one of the most attractive towns in the country. Surrounded by dramatic cliffs, and home of the famous black basalt beach, it’s easy to fall in love with this tiny town of 300 inhabitants.

Walk to the top of Reynisfjall (pictured), the largest cliff to the east of the village, and you’ll get impressive views of Reynisdrangar, basalt sea stacks shooting out of the sea just off the coast. Look northwards and you’ll be treated to a view of the impressive Mýrdalsjökull glacier.

Vík is a great jumping off point to explore some of Iceland’s most Instagram-famous spots: Skógafoss waterfall with its mystical rainbows and the abandoned DC plane (pictured) on the black beach at Sólheimasandur.

According to the Book of Settlement – a medieval document that describes how people came to Iceland – Húsavík was the first place settled by the Norse when they arrived in 870 AD. The pretty fishing village is mainly known for the many whales that live in the surrounding waters.

Húsavík is recognized as one of the best places in the world for whale watching. There are 23 species in Icelandic waters, but the most common to Húsavík and the surrounding waters are Humpback, Minke, and Blue whales.

Boat excursions to spot these magnificent creatures are available daily from the town harbor.

It's all about the whales in this part of the country, so while you're here take time to visit the Whale Museum. It's a small but fascinating exhibition with the skeletons of 10 different species of whales that inhabit the waters around Húsavík.

The highlight is the Narwhal specimen with its unicorn-like horn protruding from its skull. The museum is dedicated to the preservation of whales and has even received a UN award for environmental tourism.

The Blue Lagoon is one of Iceland’s most famous postcards, but the prohibitive price tag and popularity of the geothermal baths has led more adventurous travelers to look for alternatives like the Secret Lagoon. It’s easily accessible from Reykjavík, in the small town of Flúðir (that also boasts a surprisingly fun tomato farm).

Built as a public swimming pool in 1947, the lagoon is heated by bubbling hot springs nearby which you can wander around – just don’t fall in as temperatures exceed 212°F.

The pool isn’t huge, but the crumbling ruins of the old changing rooms shrouded in the steam rising from the hot spring makes the Secret Lagoon a surreal place. There is a small geyser that feeds into the main pool that erupts every few minutes.

It’s far more affordable than other lagoons around Iceland, and there’s a nice bar and restaurant area too. Go early in the morning or later in the evening to beat the crowds.

Egilsstaðir is a good base from which to explore eastern Iceland. It’s a charming little town on the banks of the Lagarfljot river. According to legend a huge beast known as Lagarfljótsormur inhabits the river, and is something of a local celebrity akin to the Loch Ness Monster in Scotland.

Though the town itself is fairly modest, the region around Egilsstaðir is a favorite with hikers, who come here to explore the many waterfalls, lakes, creeks, and canyons, as well as the stunning vistas from the mountaintops. Don’t miss Laugarvalladalur valley (pictured), which is full of hot springs perfect for bathing and even has a warm waterfall.

Eastern Iceland offers some of the most breathtaking coastlines in the whole island, so visitors to Egilsstadir will want to travel towards the sea to experience places like Stapavík – an ancient harbor where visitors can hike around the ruins of 15th-century fishing villages. Nearby is Stórurð – a collection of giant boulders and teal ponds just below a small glacier on the Dyrfjoll mountains.

The crowning jewels of the Westfjords, Hornstrandir Nature Reserve is a huge area in the northwest of Iceland where green fertile slopes rise into sharp cliffs that crash 1,600 feet down into the Atlantic. Only 14% of visitors who come to Iceland go to the Westfjords, so if you are after an adventure away from the crowds, look no further.

Throughout the park you can spot houses carved out of the moors, used by the original settlers of the peninsula (think Hobbit holes with grassy roofs) as well as the old farmsteads, abandoned in the 1950s. This area is also home to seals, who perch on the rocks and beaches, as well as over 30 species of birds and wild Arctic foxes (pictured).

Hornstrandir is completely isolated – there are no villages or even roads. Most people visit here with a guide, but it is possible to travel solo. It's a seriously back-to-nature experience and you're unlikely to see any other people in the reserve on your hike.

The Westfjords are so spectacular that they get a second look-in in this guide. This remote and wild region probably warrants an entire trip. It’s harder to access than much of the country, and huge portions are closed off in the winter, but it's worth the trek if you can get there at the right time of year.

Head first to Látrabjarg, the most phenomenal of all cliffs in Iceland – they are 8.5 miles long and up to 1,500 feet high.

Next head up to Selárdalur where you'll find a sculpture park. Artist Samúel Jónsson lived alone in a farm at the top of the uninhabited Selárdalur valley, and there he created a cartoonish menagerie of sculptures and hand-crafted buildings, including a chapel and museum.

Before leaving the Westfjords pop by Dynjandi (pictured) – one of the best known and most frequently visited sites of the region. This stunning collection of waterfalls makes for a gentle hike full of breathtaking views and photo opportunities.

The main cascade is not as big as Dettifoss or tall as Skógafoss, but its curious shape resembling steps is impressive in its own right.

This cluster of tiny islands off the western coast is home to one of the most beautiful historic villages in the country. The island is completely flat, as its name suggests, and is a great place for gentle walks on the beach and bird watching.

The only hotel in the island also has a reputation as something of a gourmet hotspot.

Iceland is one of the top destinations in the world for birdwatching. In Flatey twitchers will find huge colonies of puffins (pictured), eider, guillemot, and even white-tailed eagles.

For non-birders, it's one of the only places in Iceland where orca are spotted on a somewhat regular basis, usually in the summer months.

The town itself is a collection of immaculately maintained and beautifully colorful early 20th-century houses, with a church and a small harbor. Its proportions and lovely colors make it an ideal destination for enthusiastic photographers.
