Owakudani, meaning the "Great Boiling Valley," is a captivating geological site formed by a volcanic eruption over 3,000 years ago. It serves as a major source for Hakone Onsen and is renowned for its active sulfur vents, steaming hot springs, and the distinctive smell of hydrogen sulfide. This area offers a unique opportunity to witness the raw power of nature and is a must-visit for those exploring the Hakone region.
Visitors consistently praise the spectacular views, especially on clear days when Mount Fuji is visible. The scenic ropeway ride to Owakudani is often highlighted as an experience in itself, offering panoramic vistas. A central attraction is the kuro-tamago, or black eggs, which are chicken eggs boiled in the sulfuric hot springs, turning their shells black. Many reviewers mention trying these eggs, with the local tradition claiming that eating one adds seven years to one's life. Reviewers also enjoy the black vanilla ice cream and the souvenir shops offering unique local products, including Hello Kitty black egg merchandise.
To make the most of your visit, aim for a clear day to maximize the chances of seeing Mount Fuji. The best time to visit is generally in the morning to avoid larger crowds and ensure better visibility. While the black eggs are a popular novelty, some visitors advise against eating too many. The strong sulfur smell is a constant presence, which some find intriguing and others find pungent; be prepared for this. A visit typically lasts 1-3 hours, allowing enough time to explore the viewing areas, try the black eggs, and browse the shops. Wear comfortable shoes as there are walking paths, and consider bringing a light jacket as it can be windy.
Owakudani is best accessed as part of the Hakone Loop, utilizing various modes of transport. From Tokyo, take a train to Odawara, then transfer to Hakone-Yumoto. From there, buses can take you to Owakudani, or you can use the Hakone Tozan Railway and Hakone Ropeway. Many visitors recommend purchasing a Hakone Free Pass, which covers unlimited rides on most transportation within the area, including the ropeway, trains, and buses, making it a cost-effective option. The ropeway station is directly at the site, offering convenient access. Driving is an option, but public transport is highly recommended due to the integrated loop system and potential for traffic or limited parking.
A common complaint is the strong sulfur smell, which can be overwhelming for some. Volcanic activity can occasionally lead to closures of certain walking paths or even the entire area for safety reasons; it's advisable to check the official Hakone tourism website for real-time updates before your visit. While the black eggs are a novelty, some find their taste to be nothing special, so manage expectations if you're solely going for the culinary experience.
