 July is the high season in Iceland for tourism, with travelers from all around locking to the country. Below are some reasons why you should embark on an Iceland trip in July.

  • Outdoor adventures: Unlike in the winter months when the country is blanketed in snow, Iceland in July boasts stable weather conditions and the absence of snowfall, prompting the government to lift restrictions on accessing challenging F-roads that lead to some of the most picturesque hiking trails. Embark on thrilling hikes through the Thorsmork Valley along the Laugavegur trail or Fimmvörðuháls trail. You can also opt for a self-guided driving adventure along the Iceland Ring Road, making stops at iconic destinations of the Golden Circle before venturing into the mesmerizing highlands or the South Coast's black sand beaches.
  • Music festivals: July is when big-ticket music festivals take place in Iceland. Some of the most popular events include the outdoor Rauðasamdur Festival in Westfjords, the five-day Siglufjörður Folk Festival, and the four-day Eistnaflug in Neskaupstaður.
  • Puffin and whale-watching season: Puffins come to Iceland for spring and summer breeding. July falls is Iceland's peak puffin season, which offers prime opportunities to spot these charming seabirds nesting along dramatic cliffs. Similarly, June to August marks Iceland's peak whale-watching season, as warmer waters draw the humpback, minke, and even the elusive blue whales.
  • Kayaking and snorkeling: July’s pleasant weather is ideal for outdoor adventures like kayaking and snorkeling. Paddle through crystal-clear glacier-fed rivers or the Solheimajokull Glacier Lagoon with unrivaled views of the surrounding landscapes on Iceland kayaking tours. If you are up for a unique underwater experience, snorkeling in the Silfra Fissure is a must. The glacial waters boast incredible visibility and boast an optimal temperature, which is rare in other months, allowing you to witness the captivating underwater world where two tectonic plates meet.
