Thingvellir National Park can be explored in several ways, depending on your interests and the level of adventure you seek. Below are some of the most popular tours to consider when visiting during the summer.

1. Historical and Cultural Guided Tours

Thingvellir holds a special place in Icelandic history as the home of the Alþingi, Iceland’s national parliament, founded in 930 AD. A historical tour through the park offers a deep dive into the rich cultural heritage of the country, guiding visitors through the ancient site where Icelandic laws were enacted, and disputes were settled for over 800 years.

On a guided tour, you will visit key sites, including the Þingvellir Church, the Almannagjá Gorge, and the Assembly Site where the Alþingi met. Your guide will share stories and explain the historical significance of each site, including how the early Icelandic settlers governed their society and the role of the Alþingi in shaping the country’s legal framework.

Key Highlights:

• Visit the Þingvellir Visitor Center for an in-depth historical context.
• Walk through the Almannagjá Gorge, the largest rift in the park.
• Learn about the Alþingi and its influence on Icelandic democracy.

2. Snorkeling and Diving in Silfra Fissure

One of the most unique experiences available in Thingvellir is snorkeling or diving in the Silfra Fissure, a crystal-clear freshwater rift formed between the North American and Eurasian tectonic plates. Silfra is known for its exceptional water clarity, where visibility can reach up to 100 meters (328 feet).

Snorkeling in Silfra offers a once-in-a-lifetime opportunity to swim between two continents. The cold waters are surprisingly warm, especially during the summer months, and the experience is unlike any other. If you are a certified diver, diving in Silfra allows you to explore the fissure more deeply, giving you a chance to see the stunning underwater landscapes, vibrant algae, and crystal-clear water from an entirely different perspective.

Key Highlights:

• Snorkel or dive in one of the clearest waters in the world.
• Experience swimming between two tectonic plates.
• Guided tours ensure safety, providing all necessary equipment.

3. Hiking Tours Through Almannagjá Gorge

For those who love the outdoors, hiking in Almannagjá Gorge is a must. The gorge is a result of the tectonic forces between the North American and Eurasian plates and has created a dramatic landscape with stunning rock formations and steep cliffs. The hike is relatively easy and suitable for all fitness levels, offering both short and long routes.

The summer months bring lush greenery to the gorge, and hikers will encounter an array of wildflowers and plant life. Along the way, you will also find beautiful vantage points that offer panoramic views of the park, including the surrounding mountains and the crystal-clear waters of Þingvallavatn Lake.

Key Highlights:

• Explore the geological wonder of Almannagjá Gorge.
• Access various hiking routes, from easy walks to challenging treks.
• See the park from breathtaking viewpoints along the trail.

4. Lake Thingvellir Kayaking Tours

For a more relaxed activity, consider a kayaking tour on Þingvallavatn Lake. This is the largest natural lake in Iceland and offers a tranquil environment for paddling. The still waters of the lake allow for a peaceful exploration of the surrounding area, where you can get up close to the shoreline and observe the diverse birdlife that inhabits the park.

Summer is the best time for kayaking, as the weather is milder, and the days are long. A kayaking tour will guide you around the lake, providing insight into the park’s unique geology and its ecological importance. You may even get the chance to paddle in the areas surrounding the Silfra Fissure, adding a special element to your tour.

Key Highlights:

• Paddle through the serene waters of Þingvallavatn Lake.
• Learn about the unique ecosystem of the park.
• Enjoy a peaceful day out on the water with the backdrop of stunning scenery.

5. Northern Lights and Summer Stargazing

Although the Northern Lights are more commonly seen in the winter months, Thingvellir is an excellent spot for summer stargazing. The long days of summer in Iceland make it difficult to see the Northern Lights, but the summer nights still offer an opportunity to view a starry sky without light pollution. The vast open spaces of Thingvellir offer a perfect vantage point for stargazing.

Guided tours for summer stargazing in Thingvellir typically include a visit to the darkest corners of the park, where you can sit back and watch the sky for meteor showers, constellations, and other celestial phenomena.

Key Highlights:

• Stargazing tours offer incredible views of Iceland’s clear night sky.
• No light pollution, making it one of the best places for night photography.
• Enjoy the magic of Icelandic summers, even when the Northern Lights aren’t visible.
