Wonder One Music Festival returns to One Chichan at Khao Chi Chan, Pattaya, on Saturday, January 30, 2027. Here’s what we know so far about the festival, including the date and venue, what happened at the inaugural 2026 event, expected ticket information, the One Chichan festival site and what to watch for as more details are announced.
The second Wonder One Music Festival has been announced — although, for now, the organisers are keeping most of the details under wraps.
A promotional video released by the festival on September 1 confirms January 30, 2027 at Khao Chi Chan, Pattaya, while the accompanying artwork identifies the event as WONDER ONE MUSIC FESTIVAL 2027.
MILLI and NONT TANONT are the first artists announced for Wonder One Music Festival 2027, but the full lineup, ticket price and ticket-sale date have yet to be revealed.
That makes this an early look at the event — and a useful page to bookmark, as more information is expected to be released over the coming months.

The festival’s second edition is already listed by Thai music-festival directories for January 30, 2027, at Wan Chee Chan/One Chichan in Pattaya.
This page will be updated as the organisers announce the lineup, ticket information, timetable and other details.
First artists announced: MILLI and NONT TANONT
MILLI was the first artist confirmed for Wonder One Music Festival 2027, with NONT TANONT subsequently announced by the festival.
Both artists will perform at One Chichan on Saturday, January 30, with further names still to be announced.
The first two announcements suggest a broad Thai music lineup, although it is too early to say what the complete 2027 lineup will look like.
Where is Wonder One Music Festival?
Wonder One takes place at One Chichan (Wan Chichan) at Khao Chi Chan, in the Pattaya area.
The venue sits beside the famous Khao Chi Chan Buddha Mountain, with a large lake and surrounding hills providing the backdrop.
One Chichan is considerably more than a temporary festival field. The site was developed as a dedicated outdoor events destination covering more than 160 rai, with a scalable capacity of approximately 2,500 to 30,000 people. Infrastructure includes more than 200 toilets, parking for more than 4,000 vehicles and multiple access routes.
The location is approximately 30 minutes from central Pattaya by road, making it accessible for both local residents and visitors staying in the city.
What was Wonder One like in 2026?
The first Wonder One Music Festival was held at One Chichan on February 14–15, 2026, making the 2027 event a return for the festival after its inaugural Valentine’s weekend edition.
The first festival featured 16 major Thai artists across two days, with a lineup that included Jeff Satur, PALMY, Violette Wautier, ATLAS, PARADOX, URBOYTJ, Toh Saksit, Two Popetorn, B5, NONT TANONT, The TOYS, POTATO, Season Five, Slot Machine, Joey Phuwasit and F.HERO.
The music was predominantly Thai pop, rock and T-Pop rather than the international electronic-music focus associated with some of Thailand’s larger festivals.
That distinction is worth remembering when trying to guess what Wonder One 2027 might look like: no artists have yet been announced, but the inaugural event established a strong Thai pop and rock identity.
The One Chichan experience
One of the most distinctive things about Wonder One is the venue itself.
The 2026 festival was promoted around the combination of music, nature and lifestyle, with the stage and festival grounds set against the lake and Khao Chi Chan.
Rather than being a conventional city concert venue, One Chichan has open grass areas, terraces and views across the surrounding landscape. Images and attendee posts from the first Wonder One showed a mixture of concert crowds, couples, groups and families enjoying the site during the daytime before the atmosphere became more like a conventional music festival after dark.
The venue’s infrastructure was also a major part of the first festival’s appeal. One Chichan was specifically designed to address some of the problems associated with large outdoor events, including traffic management, parking, security and toilet capacity.
That infrastructure is likely to remain an important part of the Wonder One experience in 2027.
How much were Wonder One Music Festival tickets in 2026?
2027 ticket prices have not yet been announced.
However, the 2026 ticket prices provide a useful indication of the festival’s pricing.
The inaugural event was sold through ALL TICKET at 7-Eleven as well as online ticketing channels.
The advertised prices included:
- 1-Day Pass: 1,500–1,520 baht
- 2-Day Pass: 2,500–2,520 baht
- Early Bird 2-Day Pass: 2,200 baht
- Group promotions: including four tickets for the price of three
- Duo promotion: discounted two-ticket packages
A 20-baht hard-card fee applied to tickets, while children up to 110cm tall were admitted free.
It would be premature to predict the 2027 ticket price, particularly as this year’s festival is being presented as a one-day event rather than the two-day format used in 2026.
We’ll add the official 2027 prices here as soon as they are announced.
When will Wonder One 2027 tickets go on sale?
There is currently no confirmed ticket-sale date.
The 2026 festival offers a useful indication of the likely timeframe. Early Bird tickets for the inaugural event went on sale in December 2025, with further ticket sales taking place in January ahead of the February festival.
With the 2027 festival taking place on January 30, December 2026 and early January 2027 will be worth watching closely.
The 2026 festival was sold through Eventpass/ALL TICKET channels, but the organisers have not yet confirmed the sales arrangements for 2027.
Wonder One Music Festival 2027 lineup
The 2027 lineup is beginning to take shape, with two major Thai artists announced so far: MILLI and NONT TANONT.
MILLI
MILLI is the first artist announced for Wonder One Music Festival 2027. The Thai rapper and singer is known for her distinctive hip-hop style and energetic performances.
NONT TANONT
NONT TANONT has now also been announced for the festival. The singer and actor first rose to national attention after winning the first season of The Voice Thailand in 2012, before winning the fourth season of The Mask Singer in 2018.
NONT also performed at the inaugural Wonder One Music Festival in 2026, making his return to One Chichan particularly notable.
Further artists are expected to be announced ahead of the festival.
Is Pattaya becoming a festival destination?
Wonder One is particularly interesting because it arrives at a time when the wider Pattaya area is attracting an increasingly diverse range of major events.
Just six weeks before Wonder One 2027, Tomorrowland Thailand will make its full-scale Asian debut at Wisdom Valley in Pattaya from December 11–13, 2026. The festival is bringing the internationally renowned electronic-music brand to Thailand with a huge international lineup and a multi-stage production. The official Tomorrowland website says the event is already sold out.
The two festivals could hardly be more different.
Tomorrowland Thailand is an international electronic-music event expected to attract festivalgoers from around the world, while Wonder One has so far focused on major Thai pop, rock and T-Pop artists in a more relaxed lakeside environment.
Even the venues illustrate the changing events landscape around Pattaya. Wisdom Valley is a huge festival site, while One Chichan has been deliberately developed as a dedicated festival destination, with capacity ranging from smaller events through to productions for around 30,000 people.
This suggests that Pattaya and the surrounding Chonburi region could be developing into an increasingly important destination for large-scale music and entertainment events — adding another dimension to the area’s established tourism appeal.
One Chichan: a new festival destination
The development of One Chichan is arguably as interesting as Wonder One itself.
The project, associated with Ichitan founder Tan Passakornnatee, covers more than 160 rai and has been positioned as a purpose-built festival and events destination capable of hosting both national and international productions.
The venue’s design incorporates extensive parking, access infrastructure, security facilities and more than 200 toilets, while its lakeside setting and Khao Chi Chan backdrop give it something that many large urban festival sites cannot offer.
The longer-term vision goes beyond music festivals, with the wider One Chichan development intended to become a broader leisure and events destination.
That makes Wonder One worth watching even if you’re not particularly interested in the lineup: the festival is part of the emergence of a new major events venue in the Pattaya area.
Wonder One 2027: what to watch for
With the date now confirmed, the next major announcements are likely to be:
- Artist lineup – the biggest missing piece of the 2027 festival.
- Ticket prices – including any Early Bird or group promotions.
- Ticket-sale date and booking platform.
- Festival timetable – including opening and closing times.
- Festival layout and activities at One Chichan.
- Food, drink and other attractions.
- Parking and transportation information.
- Accommodation and camping information, if offered.
- Any additional stages or entertainment areas.
The 2026 event demonstrated that Wonder One can offer considerably more than a conventional concert, with the venue, scenery, food and lifestyle elements forming an important part of the experience.
Wonder One Music Festival 2027 Pattaya: the bottom line
For now, the most important information is simple:
Wonder One Music Festival returns to One Chichan at Khao Chi Chan, Pattaya, on Saturday, January 30, 2027.
The lineup and ticket information have not yet been announced, so there is no need to guess at either.
The inaugural 2026 festival featured 16 major Thai artists and established One Chichan as a distinctive new outdoor festival venue. Tickets for that event started at around 1,500 baht for a one-day pass, while a two-day pass was around 2,500 baht.
With Tomorrowland Thailand taking place in Pattaya just six weeks earlier, Wonder One’s return also adds to an increasingly interesting period for music festivals in the Pattaya area.
