Boryeong Day-Trip Course Recommendations (Daecheon Beach · Undersea Tunnel)

If you want the short answer for a Boryeong day-trip course: the smoothest order is Daecheon Beach → Boryeong Undersea Tunnel & Wonsando → Daecheon Port Fish Market → Muchangpo (or Chungcheong Suyeongseong Fortress). It’s a route that packs the sea, a scenic drive, fresh raw fish, and a sunset all into one day, so it works well for both a date and a family trip. Below, we’ve laid out the hour-by-hour route, costs, and how to get there.

Boryeong Day Trip Course at a Glance

Here’s the full route in table form. It assumes you’re getting around by car, and travel time between stops is mostly under 20–30 minutes, so it’s not too demanding.

If you’re visiting in summer (July–August), swap the afternoon stop for the Boryeong Mud Festival. Play in the mud, then rinse off right in the sea at Daecheon Beach — it fits the route perfectly.

Daecheon Beach — Where the Course Begins

The heart of any trip to Boryeong is Daecheon Beach. A broad, roughly 3.5 km stretch of white sand runs along the coast, with a mud plaza, fountains, and shops all clustered nearby — making it a great base camp for the day.

One thing you shouldn’t skip here is the Daecheon Sky Bike. It’s a bike ride along a 2.3 km rail over the water connecting Daecheon Beach and Daecheon Port, taking about 40 minutes round trip. The fare is 22,000 won for a 2-seater, 26,000 won for a 3-seater, and 30,000 won for a 4-seater (source: Boryeong Facilities Management Corporation), and during the peak season of June–August it runs from 10 a.m. to 6 p.m. It’s closed every Monday and on Lunar New Year’s Day and Chuseok.

The Sky Bike can’t be reserved in advance — tickets are sold same-day at an on-site kiosk. Lines can get long on weekends and during peak season, so it’s a good idea to buy your ticket as soon as you arrive.

Lunch at Daecheon Port Fish Market

About a 10-minute drive from the beach — and also the endpoint of the Sky Bike ride — Daecheon Port Fish Market is the go-to lunch spot. You’ll find fresh raw fish and seafood here for relatively less than at the shops around Daecheon Beach. Buy sliced raw fish downstairs and eat it upstairs at one of the dipping-sauce restaurants, or pick out seasonal seafood like pen shell clams and shrimp.

Since the next stop is right next door, there’s no wasted travel time after your meal. If you’re traveling with family, there are plenty of options besides raw fish too — like fried shrimp or seafood kalguksu (noodle soup) — so it’s easy even with kids along.

Boryeong Undersea Tunnel and a Drive to Wonsando

After lunch, head to Boryeong’s signature attraction, the Boryeong Undersea Tunnel. Stretching 6,927 m between Daecheon Port and Wonsando Island in Ocheon-myeon, it’s the longest undersea tunnel in Korea. It opened in December 2021, and since there’s no toll, it’s a popular drive.

Wonsando, which used to require a boat to reach, is now just a 20-minute drive from Daecheon. It has small, low-key attractions like the quiet shore of Wonsando Beach and cafés run by young local farmers using regional specialty products. If you have extra time, you can keep driving past the tunnel all the way to Anmyeondo.

Muchangpo Mystic Sea Road vs. Chungcheong Suyeongseong Fortress

For the afternoon stop, pick one of the two depending on the tide schedule.

• Muchangpo Mystic Sea Road: At low tide, a roughly 1.5 km sand path opens up between Muchangpo Beach and Seokdaedo Island — Korea’s version of the “parting of the sea.” The road opens at a different time each day, though, so checking the tide table before you go is a must.
• Chungcheong Suyeongseong Fortress: A stone fortress built in 1509, with great views overlooking Ocheon Port. It became even more famous after appearing as a filming location for the drama When the Camellia Blooms. You can drop by anytime regardless of the tide, which makes it the easy, no-fail option.

If the tide works out, go to Muchangpo; if not, go to Chungcheong Suyeongseong Fortress. Staying flexible this way means you really can’t go wrong.

In Summer, Swap in the Boryeong Mud Festival

If you’re visiting Boryeong in July or August, we recommend spending the entire afternoon at the Boryeong Mud Festival. In 2026, the 29th edition runs July 24 to August 9 at the Mud Expo Plaza around Daecheon Beach (source: Boryeong Festival Tourism Foundation). The Mud Expo Plaza is about a 5-minute walk from Daecheon Beach, so you can play in the mud to your heart’s content and then head straight into the sea to rinse off.

There’s a wide range of programs, including the mud experience zones (Mud Run, Family Zone, Water Park Zone), the Mud Mob performance, and color mud painting. The main experience zones require a paid ticket, so it’s best to check the exact fees and hours on the official website ahead of time.

During the mud festival, parking and traffic around Daecheon Beach get extremely congested. If possible, arrive in the morning or use public transit or a shuttle.

Since it’s in the same Chungnam region, if you have extra time, consider following up with the Gongju Baekje History Day Trip Course as your next stop.

Boryeong Trip Pre-Visit Checklist

Check these off before you leave and your route will go a lot more smoothly.

• If you’re heading to Muchangpo, check the tide table first (the sea road opens at a different time every day)

• In summer, check the mud festival dates and experience-zone fees on the official website
• Daecheon Port Fish Market is your best bet for an affordable lunch

• Time your last stop to catch the sunset at Daecheon Beach

Frequently Asked Questions (FAQ)

Can I do a Boryeong day trip without a car?

You can reach places like Daecheon Beach, the mud festival grounds, and Daecheon Port by public transit. But if you want to visit more spread-out spots like the Boryeong Undersea Tunnel, Wonsando, and Muchangpo, a car is much more convenient. Without one, it’s best to keep your route focused around the beach area.

How much is the toll for the Boryeong Undersea Tunnel?

It’s free. Built as part of National Route 77, you can drive through without paying any toll. It’s about a 20-minute drive from Daecheon Port to Wonsando.

What are the fares and hours for the Daecheon Sky Bike?

It’s 22,000 won for a 2-seater, 26,000 won for a 3-seater, and 30,000 won for a 4-seater. From June to August it runs from 10 a.m. to 6 p.m., and it’s closed on Mondays and on Lunar New Year’s Day and Chuseok. Tickets are sold on-site only.

Can I see the Muchangpo Mystic Sea Road anytime?

No. The roughly 1.5 km sea road only opens at low tide. Since the time it opens changes daily, be sure to check the tide table before your visit.
