Hua Hin to Chumphon, Thailand: A Slower Route Down the Gulf Coast

Last month, a friend from Koh Tao was traveling to Hua Hin to kitesurf, and I decided to come along to get caught up on some much-needed appointments that aren't readily available on a small island like Koh Tao.

As my friend ripped through the waves like the badass woman she is, I saw the doctor, the dentist, and finally got a long-overdue haircut.

But the real adventure for me started after that. If you’re wondering how to get from Hua Hin to Chumphon, Thailand—and whether it’s worth stopping along the way—this route has more to offer than most people realize.

Hua Hin to Chumphon: What’s In Between

Hua Hin sits a few hours south of Bangkok—easy, developed, and honestly a bit of a reset after the chaos of the city. Chumphon is further down the Gulf coast and acts as the main gateway to islands like Koh Tao.

Everyone’s racing between Bangkok and the islands—meanwhile, the coastline between Hua Hin and Chumphon just quietly exists. But what’s in between?

If you’re trying to figure out how to get from Hua Hin to Chumphon (and whether it’s worth stopping along the way), here’s exactly what it’s like.

Options and Costs to Get from Hua Hin to Chumphon, Thailand

Getting from Hua Hin to Chumphon is straightforward. What’s not so apparent is deciding how you want to do it—because each option gives you a completely different experience.

Option 1: Direct Bus (What I Did First)

I originally took the Lompraya bus from Chumphon up to Hua Hin.

It’s one of the easiest ways to move between the mainland and the islands, especially if you’re coming from Koh Tao.

• Cost~ $26 USD

• Time: 5-6 hours, depending on traffic

• Comfortable, air-conditioned

• Designed for island connections

• No thinking required

If your goal is just to get from point A to point B, this works.

Option 2: Train (What I Took Back South)

On the way back, I took the train from Prachuap Khiri Khan down to Chumphon—and honestly, this was my favorite part.

• Cost: ~ $8 USD

• Time: less than 4 hours

• Easy to book at the station

There’s something about train travel in Thailand that slows everything down in the best way.

You’re not rushing. You’re just moving through it.

Option 3: Private Car / Taxi (Best for Flexibility)

This is where the trip opened up for me.

• Hua Hin → Dolphin Bay (Grab): ~ $15 USD

• Dolphin Bay → Cave → Prachuap Khiri Khan (local driver): ~ $50 USD

There’s no Grab in places like Sam Roi Yot, so hiring a local driver is often the easiest way to see anything beyond your hotel. This is what gives you access to the in-between places most people miss.

Option 4: Motorbike or Rental Car (What I Plan to Do Next Time)

A good option from Dolphin Bay to Sam Roi Yot National Park, if you plan to spend multiple days exploring, is to rent a motorbike. In hindsight, the most economical trip would be to rent a car in Chumphon or Hua Hin. This is also only if you are comfortable driving in Thailand and have an international driver's license.

Dolphin Bay (Sam Roi Yot): Where the Pace Changes

As soon as the Grab driver turned onto the beach road, I knew I had made the right decision.

The hustle and bustle of Hua Hin faded almost instantly, replaced by white sand, towering karsts, and, unexpected to me, pine trees lining the shore.

Dolphin Bay is magical. Wide open beach, barely anyone around, longtail boats sitting quietly in the water, and very few Western tourists. Nothing staged or trying to impress you.

I stayed at Blue Beach Resort, a simple spot just a short walk from the beach, for about $24 USD a night. The gardens were impeccably kept, the rooms were comfortable, and it had that relaxed, easy feel that fits this area perfectly. In hindsight, I would have splurged the extra couple of dollars for one of the private bungalows—but I’ll save that for next time.

My day was spent walking miles along a mostly deserted beach—except for the occasional ATV (quad bike) carrying Thai tourists up and down the shoreline.

For dinner, I ended up at an Indian restaurant right on the beach—another surprise—and met the owner from India, along with a French guy who later drove me about 2 miles to 7-Eleven in his sidecar (selang) so I could grab sunscreen and bug spray.

The only downside to Dolphin Bay is that once the sun goes down, it’s quiet—like nothing is happening at all. Granted, it was low season, but the pace here is beyond slow. As much as I enjoyed my time, I found myself ready for the hike the next day.

Phraya Nakhon Cave in Sam Roi Yot National Park: Logistics, Cost & What It’s Really Like

If you’re a hardheaded traveler like me, you know there are some things you just can’t get out of your head. This cave in Sam Roi Yot National Park was one of them. Anyone who knows me knows I detest hiking—but something about this kept pulling at me. I had to do it.

I searched online trying to find clear information about the options, but everything I found was either vague or conflicting. So I did what I usually end up doing—I went anyway and figured it out for myself.

Getting to Phraya Nakhon cave isn’t as straightforward as it sounds.

You have two options:

• Walk to the trailhead → adds a few extra kilometers in the heat

• Hire a longtail boat → about ~$12 USD round trip

I took the boat. For me, it was totally worth it, not just for the distance, but for the heat. By the time you even reach the start of the hike, you’ll feel it.

The Hike Itself

This is not a casual walk.

• Steep inclines

• Uneven terrain

• Exposed sections with direct sun

• Heat that builds quickly

There are a few points where I questioned my life choices, but then I just kept going.

I saw people doing it in Crocs and Birkenstocks—which… you can do—but it’s not ideal.

I had just bought a pair of knock-off K-Swiss tennis shoes in Hua Hin, and that turned out to be one of my better decisions.

Cost Breakdown

• Park entrance: ~200 baht (~$6 USD)

• Boat (optional): ~$12 USD

  
  

Inside Phraya Nakhon Cave

When you reach the top and step inside, everything shifts. The temperature drops slightly, and the noise disappears.

Light filters through the opening in the ceiling and lands directly on the royal pavilion in a way that almost feels like a Hollywood set, but isn't. And the overwhelming feeling is relief and awe.

NOTE: There are other caves and amazing things to do in the Sam Roi Yot National Park. I would recommend spending at least 2-3 days exploring.

Hike Essentials

• Proper shoes - hiking and water shoes

• Water - more than you think you need

• Sunscreen - you’ll be exposed most of the hike

• Bug spray - especially if you’re lingering anywhere shaded

• Small backpack - hands-free makes a difference on the climb

• Cash - park entrance + boat

• Hat or sunglasses - very little shade in sections

• A Snack - it's a long way up and down

• A Handheld Electric Fan - I wasn't a fan until this hike (see what I did there)

If you’re reading this and thinking, this sounds amazing but also kind of complicated—you’re not wrong. This is exactly the kind of trip that’s hard to piece together from Google alone. If you want help planning something similar—what to skip, where to stop, and how to make it all flow—I offer one-on-one guidance based on actually living and traveling here.

Prachuap Khiri Khan — Not What I Expected

After my big adventure to the cave, I was ready for my next destination and a shower. The driver I hired in Dolphin Bay drove me an hour south to Prachuap Khiri Khan.

Prachuap Khiri Khan is a small coastal town, not a resort hub. Mostly locals—fishing families, Thai military, everyday life. It’s actually a provincial capital, but it doesn’t feel like one.

The layout is simple: a quiet strip of town hugging a curved bay—Ao Prachuap—with a long waterfront promenade. Everything kind of orbits that. Walk one direction, and you’re in town. The other, and you’re just watching the sea.

There is also a temple on a hill. Khao Chong Krachok rises right out of town, with about 300+ steps; it's one of the best views in the area. Beware of the monkeys along the way.

Accommodation in PKK

My hotel was called Jungle Cafe, a small vintage coffee shop with rooms tucked above it.

The space was full of character—antique lamps, a rotary phone, little details that made it feel more like a curated collection than a hotel.

The owner insisted I take a room on the top floor overlooking the sea, and she was absolutely right. There was a shared bathroom, which normally wouldn’t be my first choice, but it was brand new—spotless, modern, and clearly well cared for—so it didn’t matter.

One of The Best Night Markets in Thailand

The social highlight of Prachuap Khiri Khan is a night market every Friday and Saturday, and it was one of the best I’ve been to in Thailand. The market starts at sunset and runs along the oceanfront walking street for about half a kilometer—just line after line of incredible food, locals everywhere, and actual local prices.

A fresh coconut—20 baht.

Pad Thai—40 baht.

Back along the boardwalk, a group of Thai kids was singing and playing music with donation boxes set out in front of them. They lit up when I stopped to listen. I dropped 20 baht into all of the jars, and their reaction alone was worth it.

Why I Love PKK and Why You Should Visit

The next morning, I woke up at sunrise and stepped out onto the terrace. Below me, local fishermen were weighing and selling their overnight catch. It felt like I had quietly slipped into the rhythm of the town in my slumber, and I love it.

Prachuap Khiri Khan is a hidden gem along the Gulf of Thailand, and I’ll 100% be back for a longer stay. With very few farang visitors, the locals are genuinely curious and friendly. It felt like an older version of Thailand—the one you don’t see as much in more touristy places.

At 7-Eleven, the woman behind the counter came out to greet me and handed me a shopping basket, as if I’d walked into a small neighborhood shop instead of a chain.

At a coffee shop, the baristas practiced their English with me, laughing through it, then asked for a photo together.

One of the best parts about Prachuap Khiri Khan is how easy it is to reach—right on the Southern train line from Bangkok. An affordable and easy 2 hours from Hua Hin to the north and Chumphon to the south.

The Easiest Leg — Train to Chumphon

After everything it took to get to the cave and then into Prachuap Khiri Khan, the train to Chumphon felt almost too easy. I showed up, got on, and watched the coastline pass by.

If you have more time, one place worth looking into along this route is Ban Krut.

I didn’t stop there, but it’s another quiet coastal town that feels very much in line with this stretch of Thailand—low-key, local, and easy to reach by train. Next time for sure!

Final Thoughts

This stretch from Hua Hin to Chumphon wasn’t the easiest route to plan that I’ve taken in Thailand—but that’s exactly what made it memorable. From the confusion of getting to the cave, to the quiet reset in Dolphin Bay, to the old-school charm of Prachuap Khiri Khan, to the simplicity of the train heading south—it all balanced out in a way I didn’t expect.

Was it worth it to me?... Absolutely!
