Begin your journey at the Adex Base, where we will meet 15 minutes before the tour starts. Here, you'll have the opportunity to check your gear, ensure you're comfortably dressed for the adventure, and complete any necessary formalities.
Our main trek starts at the Sun Lavia Ski Resort. You'll strap on your snowshoes and follow a path blanketed in pristine snow through a serene forest. This leg of the journey, taking around 150 minutes, is an immersive experience in the tranquility of nature.
The highlight of the tour is the Karurusu Ice Cave. Due to space constraints, exploration is done in small groups of two, ensuring an intimate and optimal experience. While waiting, you can enjoy the spectacular views from the cave's mouth and take a well-deserved break in this sheltered spot. Expect to spend about 90 minutes here, marveling at the natural ice artistry.
After the cave exploration, we make our way back along the forest trail to the Sun Lavia Ski Resort. This return journey, taking approximately 100 minutes, allows you to reflect on the day's experiences. A shuttle bus awaits to take you back to the Adex Base.
Our adventure concludes back at the Adex Base. Here, we part ways, enriched by the day's unique experiences and carrying memories of a magical winter escapade.
