Eastern Thailand rarely gets the attention northern Thailand’s famous loops receive, and for riders who’ve already done the Mae Hong Son Loop and are looking for something genuinely different, that’s exactly the appeal. Within a comfortable ride of Pattaya sits a quieter, considerably less documented region combining coastal headlands, genuine fruit orchard country, twisting mountain roads through jungle waterfalls, and one of Thailand’s most celebrated national parks. This guide rounds up four ways to experience it, a straightforward coastal run from Pattaya through Rayong to Chanthaburi, the continuation on to Trat, a combined mountain-and-coast loop around Chanthaburi itself, and an inland detour to Khao Yai for riders wanting real wildlife country.

Why eastern Thailand rewards a proper look

It’s worth understanding what sets this region apart from the more heavily covered north. Eastern Thailand genuinely offers real variety within a compact, easily accessible area, coastal seafood towns, working fruit orchards that supply much of the country’s durian and rambutan, jungle-covered mountains, and a UNESCO World Heritage rainforest park all sit within a few hours of each other and of Bangkok itself. The riding here is generally gentler than the north’s technical mountain routes, making this a genuinely good option for riders wanting real scenery without the sustained technical demand of routes like Route 1095 or Doi Ang Khang.

1. Pattaya to Rayong to Chanthaburi

Distance: ~180 km  |  Character: Easy coastal riding through fruit country

Heading southeast from Pattaya, the coast road runs through Rayong before continuing to Chanthaburi, genuinely comfortable riding on good roads throughout. This stretch delivers a real sense of Thailand’s eastern seaboard beyond Pattaya’s busier tourist strip, quieter seaside scenery and proper seafood towns worth building stops around.

Points of interest

• Khao Chi Chan (the Buddha Mountain): A genuinely striking 109-metre gold Buddha image carved into a cliff face near Pattaya, worth an early morning or late afternoon visit specifically to avoid the daytime crowds this popular site draws.
• Anek Kusala Sala: A museum blending Thai and Chinese influences with a genuinely impressive collection of sculptures and bronze figures, worth a stop for riders interested in something beyond scenery.
• Rayong’s coastline: Worth a proper stop along the way, considerably quieter beaches than Pattaya itself.
• Fruit orchards approaching Chanthaburi: This stretch genuinely runs through some of the country’s most productive durian, rambutan and mangosteen growing country, worth timing a visit around local harvest season if fresh fruit direct from roadside stalls is a priority.
• Chanthaburi’s old waterfront community: Genuinely worth a proper walk, a historic riverside quarter known for well-preserved architecture and a distinctly different atmosphere from the coastal towns further back along this route.

2. Chanthaburi to Trat

Distance: ~90 km  |  Character: Quieter headlands and beaches

Continuing southeast from Chanthaburi toward Trat, the coast becomes noticeably quieter and more dramatic, genuine headlands and beaches considerably less developed than anywhere near Pattaya. This is worth the extra distance specifically for riders wanting a proper coastal escape rather than the busier tourist infrastructure further north along the Gulf.

Points of interest

• Coastal headland viewpoints: Several worthwhile stops along this stretch, genuinely dramatic coastal scenery worth slowing down for.
• Trat town: Worth knowing as the mainland gateway for riders continuing on to Koh Chang, covered in full depth in this guide series’ dedicated Koh Chang Island Ride guide, a natural extension for this coastal route.

3. The Chanthaburi Mountain and Coast Loop

Distance: ~150-180 km  |  Character: Combining both sides of the province’s character in one ride

For riders wanting the fullest picture of Chanthaburi province in a single trip, this loop genuinely combines its coastal and mountain sides rather than choosing one. The route runs through Khao Chamao National Park, delivering roughly 100 km of genuinely twisting mountain roads, before connecting back to the coast for dramatic headland riding, a real change of pace within a single day or overnight.

Points of interest

• Khao Chamao National Park: Genuinely worth building real time around, jungle waterfalls with swimming pools set within a properly scenic mountain park, a highlight of this entire loop.
• Namtok Phlio National Park: A scenic park roughly 170 km southeast of Pattaya, worth a stop for its own waterfalls and forest scenery.
• Mount Khitchakut: Home to a sacred balancing rock and Buddha footprint near the summit, worth knowing about for riders interested in a stop with genuine local religious significance.
• Coastal headland stretches: The loop’s coastal half delivers genuinely dramatic views, a fitting contrast to the jungle riding through Khao Chamao earlier in the route.

Road conditions

Genuinely good throughout, this loop mixes twisting mountain sections through the national park with more open coastal riding, worth taking the mountain stretch specifically at a measured pace given the sustained curves involved, considerably gentler than northern Thailand’s technical climbs but still worth real attention.

4. Khao Yai National Park: an inland detour into wildlife country

Distance: ~200-250 km from Pattaya or Bangkok  |  Character: Smooth, accessible riding through Thailand’s first national park

Sitting inland from this coastal region, Khao Yai is genuinely Thailand’s first national park and a UNESCO World Heritage Site, covering more than 2,000 square kilometres of rainforest and grassland across several provinces. This is worth treating as a separate detour rather than a direct extension of the coastal route covered above, but genuinely worth combining into a longer eastern Thailand trip for riders with the time.

Points of interest

• Haew Suwat Waterfall: A genuinely picturesque roughly 20-metre cascade within the park, made internationally recognisable by its appearance in a well-known film, worth a proper stop.
• The park’s mountain roads: Climbing up to roughly 1,351 metres elevation, offering genuinely panoramic jungle vistas, smooth and well-paved throughout, making this one of the more accessible national park rides covered anywhere in this guide series.
• Wildlife viewing opportunities: Genuinely real, this park is home to wild elephants, gibbons, deer and considerable birdlife, worth riding at a measured pace and staying alert for genuine wildlife encounters rather than expecting a guaranteed sighting.
• Local vineyards near the park: Worth knowing about for riders interested in something beyond nature and wildlife, several wineries have established themselves in this area’s cooler elevated terrain.

Road conditions

Genuinely among the most accessible national park riding covered in this guide series, smooth, well-paved roads with less demanding terrain than the mountain routes further north, making this a genuinely good option for riders wanting a leisurely ride with plenty of stops for nature and photography rather than a technical challenge.

Combining these four into a longer eastern Thailand trip

Riders with a full long weekend or more should genuinely consider combining several of these routes rather than choosing just one. A common and rewarding pattern rides from Pattaya through Rayong to Chanthaburi on day one, takes the Mountain and Coast Loop as a proper day two, continues on to Trat for a coastal finish, and, for riders with the time, either connects on to Koh Chang or loops back inland toward Khao Yai as a considerably different final stage before returning to Bangkok or Pattaya.

Best time of year to ride

November through April is genuinely the reliable window across this region, matching the wider Gulf coast’s dry season. It’s worth knowing eastern Thailand’s rainy season can bring genuinely heavy downpours given the region’s proximity to both the Gulf coast and dense inland rainforest around Khao Chamao and Khao Yai specifically, worth building extra schedule flexibility into any trip attempted during the wetter months.

What kind of bike suits these routes

Given the generally gentle terrain throughout most of this region, these routes are genuinely accessible to a wide range of bikes, a 125cc to 150cc scooter handles the coastal and Khao Yai riding without real difficulty. The Chanthaburi Mountain and Coast Loop’s twisting sections through Khao Chamao specifically reward a bit more power for comfortable overtaking and sustained curves, though it remains accessible to smaller bikes at a measured pace. Compare motorbike rental options before setting off, with Pattaya offering genuine rental availability as a natural starting point for this entire region.

A few scenarios, worked through

A rider with a single day from Pattaya should genuinely ride the straightforward run to Chanthaburi and back, treating the fruit orchards and old waterfront community as the day’s highlights rather than pushing on to Trat. A rider with a proper weekend should genuinely take the Chanthaburi Mountain and Coast Loop specifically, combining Khao Chamao’s jungle waterfalls with the coastal headlands for the fullest single-trip picture of the province. And a rider with a full week and genuine interest in wildlife should genuinely build in a separate day or two at Khao Yai, treating it as its own dedicated detour from the coastal riding rather than trying to combine both regions into a single rushed day.

How this connects to the wider ride

This eastern Thailand region connects naturally into this guide series’ dedicated Koh Chang Island Ride, with Trat serving as the mainland gateway for the ferry crossing. Riders continuing further along the coast toward the Cambodian border can extend beyond Trat for additional coastal exploration, and riders based in Bangkok or Korat specifically interested in Khao Yai without the coastal detour can approach the park directly rather than via this guide’s Pattaya-based route.

Final thoughts

Eastern Thailand genuinely offers a compelling alternative for riders who’ve already explored the north’s famous loops, real coastal scenery, genuine fruit orchard country worth timing around harvest season, twisting jungle mountain roads, and one of the country’s most significant national parks, all within easy reach of Pattaya or Bangkok. For a shorter trip that still delivers real variety without the sustained technical demand of northern Thailand’s mountain routes, this region deserves considerably more attention than it typically receives.

Build any of these routes on the Thailand Explorer, compare motorbike rental options if you’re not yet on two wheels, and get properly covered before you ride.
