If you are planning an evening along the Han River (Hangang) in Seoul, it helps to understand how the Night Market, Overnight Camping, and Night Picnics work, as the city has specific rules for each.

1. Hangang Moonlight Night Market (한강달빛야시장)

The Hangang Moonlight Night Market is one of Seoul’s most popular seasonal events, featuring dozens of food trucks, handmade craft stalls, and live street performances.

• Locations:

  • Banpo Hangang Park: Typically operates during late spring (May–June) alongside the Banpo Bridge Moonlight Rainbow Fountain show.

  • Yeouido Hangang Park: Typically operates during early autumn (September–October).

• Operating Hours: Usually weekends (Saturdays & Sundays) from around 5:00 PM to 10:00 PM.

• Highlights: International street food, local desserts, artisan markets, and riverside skyline views.

2. Overnight Camping: Nanji Camping Site (난지캠핑장)

If you want to do actual overnight camping or outdoor BBQing, you cannot pitch a tent on the general grass lawns. You must go to an official campground.

• Location: Nanji Hangang Park (Mapo-gu).

• Options Available:

  • Glamping / Cabin Zones: Pre-furnished tents/cabins for visitors without gear.

  • General Camping Zones: Bring-your-own-tent slots.

  • Barbecue Zones: Day-use picnic tables with grills (no overnight stay required).

• Facilities: Showers, sinks, convenience store, grills, and electricity.

• Booking: Reservations are required in advance through the Seoul Public Service Reservation System or Interpark, as spots sell out very quickly.

3. Pop-Up Shade Tents vs. Night Picnics

If you want to set up a small shade tent or picnic on the open grass parks (like Yeouido, Banpo, or Ttukseom), keep these city rules in mind:

Daytime Pop-Up Tents

• Designated Areas Only: Tents can only be set up in marked "Tent Zones".

• Requirements: Tents must be small (maximum 2m × 2m) and have at least two sides fully open at all times for safety/visibility.

• Strict Curfew: Tents are allowed during daytime hours only and must be taken down by 7:00 PM (extended to 8:00 PM in peak midsummer). Setting up tents overnight on regular park grass is prohibited and subject to fines.

Evening "Night Picnic" (The Local Alternative)

After tent curfew, locals transition to Night Picnics on picnic mats:

• Rental Shops: Rental booths near major park entrances (Yeouido, Banpo, Ttukseom) rent out picnic packages starting at ~₩5,000–₩15,000. These usually include a picnic mat, a small portable table, mood lamps, and backrest chairs.

• Food & Drinks: Get instant self-cooking ramen (Hangang Ramen) from park convenience stores, or order delivery fried chicken (Chimaek) directly to dedicated delivery pickup points in the park.
