Boryeong Cold Wind Bath: A 12°C Summer Escape from a 200 m Abandoned Seongjusan Mine

How a 200 m Abandoned Mine Tunnel on Seongjusan Became a Summer Retreat

Boryeong Cold Wind Bath is a facility that uses the phenomenon of underground cold air escaping from an abandoned mine tunnel on the northern slopes of Seongjusan. According to Boryeong City materials, one 200 m cold-wind tunnel extending from the mine entrance was created, along with 16 button mushroom cultivation houses, one visitor information center, and one specialty product sales facility.

The cold wind rises from deep within the abandoned mine tunnels extending hundreds of meters underground. Chungnam Tourism explains that the interior remains at approximately 12℃ even when outdoor temperatures exceed 30℃, and that the cold wind feels stronger as the outside temperature rises. In other words, this is not a facility replacing the sea or a valley, but a place that transforms Boryeong’s coal-mining heritage and underground environment into a summer experience space.

In Summer 2026, Call First to Confirm Whether It Operates from 09:00 to 18:00 in July and August

The basic operating schedule in official tourism information is 09:00–18:00 in July and August, and the facility is closed outside July and August. Admission and parking are free. A recently published 2025 notice stated that it operated for 66 days from June 27 to August 31, but the exact opening dates may vary each year. Therefore, on the day of departure, confirm whether it is open by calling the Boryeong Tourism Information Center at 041-930-0980 or the Cold Wind Bath operations inquiry number at 041-930-7651.

The address is 190 Naengpungyokjang-gil, Cheongna-myeon, Boryeong-si, Chungcheongnam-do. Restrooms are available and separated by gender, while a rest area and walking trail are also listed as available facilities. No separate admission reservation is indicated, but visitors planning to come outside the operating period are advised to contact the Guidance and Planning Team at the Boryeong Agricultural Technology Center in advance.

Why to Bring Long Sleeves and a Towel for the 12℃ Cold-Wind Tunnel and Cold-Foot-Bath Area

The perceived temperature is especially low in the section where the cold wind first emerges. A July 2025 Chungcheongnam-do field report recommended bringing a long-sleeved outer layer or a large towel when entering the tunnel, and noted that towels and changing rooms were not provided separately on site. Rather than staying for a long time in midsummer clothing, it is better to prepare a lightweight long-sleeved shirt, a dry towel, and non-slip shoes.

Outside, there is a foot-bath and water-play area using water cooled by the abandoned mine’s cold air. According to the guidance, the foot-bath water is replaced with fresh water every morning after cleaning. Visitors must remove their shoes, avoid running, refrain from cooking, drinking alcohol, and smoking, and avoid stepping on the deck seating areas. Reviews repeatedly mention that the water is extremely cold, so children should use it briefly rather than stay in for a long time, while monitoring changes in their body temperature.

A Practical Choice Between Parking for 30 Small Cars and 3 Large Vehicles and Public Transportation

Parking is listed as accommodating 30 small vehicles and 3 large vehicles, with no fee. Since this is a summer-only attraction located on the mountain slopes of Cheongna-myeon, a passenger car or rental car is the simplest way to reach it, especially for groups or visitors carrying water-play equipment. There have been reports of seasonal staff being stationed in the parking lot, but this cannot be assumed to be the same every year, so follow instructions on site.

The official tourism page did not provide the number of a specific city bus, the stop, or walking time. If visiting solely by public transportation, it is safest to check separately on the day of travel whether buses from central Boryeong or Daecheon Station toward Cheongna-myeon are operating and where to get off, then arrange a taxi connection. The official information does not confirm whether dedicated ramps for wheelchairs and strollers, rental services, or regularly available foreign-language assistance are provided.

How Sales Work at the Village 1-ri and 2-ri Stalls Selling Cold-Wind-Grown Mushrooms

Around the Cold Wind Bath, visitors can find button mushrooms cultivated using natural airflow from the abandoned mine. Chungnam Tourism introduces nearby restaurants where dishes made with these mushrooms can be enjoyed, while a 2025 Chungcheongnam-do field report states that mushrooms and aralia shoots grown in the cold wind were sold near the exit at the end of the tunnel. Items available for sale and stock may vary depending on the season and weather.

The village stalls were jointly operated by 1-ri and 2-ri, but a 2025 field report states that payments were handled separately. The report introduced 1-ri as offering specialty products, sikhye, and coffee drinks, while 2-ri had a higher proportion of prepared foods. Even if you order everything at once, payment may be split, so preparing cash or a payment method that allows separate transactions can reduce confusion.

A Half-Day Northern Seongjusan Route Combined with Cheongcheonho, Completed in 1962

Nearby Cheongcheonho is a reservoir completed in 1962 by building an embankment across a low basin between Oseosan and Seongjusan. Boryeong City materials describe Cheongcheonho as covering 2,772,000㎡ and rank it among Chungcheongnam-do’s three major reservoirs, together with Yedang Reservoir and Tapjeong Reservoir. It is also mentioned as a fishing spot inhabited by native fish such as crucian carp, carp, and catfish, as well as a habitat for egrets.

After visiting the Cold Wind Bath, it is natural to continue walking along the waterside deck at Cheongcheonhosu Park. The park has a parking lot and convenience facilities, with no separate admission or parking fee. However, the Cold Wind Bath operates only seasonally in summer, while lakeside walking is an outdoor activity. For an efficient route, use the tunnel and foot-bath area first around midday, then move to the waterside deck later in the afternoon.

An Order of Activities That Foreign and Family Travelers Can Complete in 40–60 Minutes

The recommended stay is approximately 40–60 minutes, including a round trip through the tunnel and outdoor foot-bath time. After parking, first check the restroom location and operating information, then walk slowly through the cold-wind tunnel and back while wearing a long-sleeved layer. Next, briefly use the foot-bath or water-play area, and finish by viewing the mushroom and local agricultural product stalls. Since the abandoned-mine cold-wind tunnel is the main attraction, it may not suit travelers expecting a place for extended outdoor water play.

If traveling with children, prepare towels, spare clothes, and non-slip sandals, and have an accompanying adult regulate the time spent in the cold wind and cold water. Pets are reportedly not allowed, and stroller rentals are unavailable. Whether permanent English, Chinese, or Japanese commentary or information materials are provided has not been confirmed, so foreign visitors should save the address and operations inquiry number and prepare a translation app as well.
