Onuma Quasi National Park

Onuma Park (大沼公園, Ōnuma Kōen), located just 20 km north of Hakodate, is a scenic haven and "quasi-national park" that is easily accessible via Onuma Koen Station on the train line between Hakodate and Sapporo. The park is renowned for its tranquil lakes, verdant walking trails, and the stunning backdrop of Mount Komagatake, an active volcano that dramatically enhances the park’s natural beauty. Whether you're passing through on a longer journey or taking a day trip from Hakodate, Onuma Park offers an ideal escape into nature, allowing visitors to unwind in a serene environment surrounded by lush greenery and striking landscapes.

The area between the larger Lake Onuma and the smaller Lake Konuma is particularly popular, offering picturesque walking paths and quaint bridges that connect the islands scattered across the lakes. Visitors can also explore the park by cycling around Lake Onuma or enjoy a leisurely boat cruise. For those looking for more active outdoor pursuits, the park offers canoeing, fishing, and camping opportunities. In the warmer months, sightseeing cruises depart every 40 minutes, providing a relaxing way to take in the breathtaking views and fully appreciate the natural beauty of this tranquil retreat.
