10-Day Thailand Itinerary (Bangkok, Chiang Mai)

Quick answer: This 10-day Thailand itinerary covers the must-see highlights without rushing, with detailed day-by-day plans, restaurant recommendations, and budget guidance.

Best for: First-time visitors who want to maximize sightseeing while still tasting local culture.

Day 1 — Landing in Bangkok

Most US travelers connect through Tokyo, Seoul, Taipei or Doha into Suvarnabhumi Airport (BKK) after a 20—24 hour journey, landing bleary-eyed but buzzing. Skip the taxi scrum: the Airport Rail Link runs into the city for roughly 45 baht (about $1.30) in 30 minutes, connecting to the BTS Skytrain. Fill in the mandatory Thailand Digital Arrival Card (TDAC) online before you fly, and remember US passport holders currently get 30 days visa-free (down from 60 as of 2026). Base yourself around Sukhumvit or Silom for easy transit. Grab a prepaid eSIM (AIS or TrueMove, roughly $8—15 for the trip) at the airport or in-app. Ease jet lag with a first meal of boat noodles or pad see ew at a street stall, then an early night. Insider tip: carry small bills—many stalls and songthaews cannot break a 1,000-baht note.

Day 2 — Grand Palace & Riverside

Start at the Grand Palace and Wat Phra Kaew (Temple of the Emerald Buddha) right at the 8:30am opening to beat heat and crowds; entry is about 500 baht (roughly $14). Dress modestly—covered shoulders and knees are strictly enforced, and touts at the gate who claim it is “closed” are running a scam. Walk 10 minutes to Wat Pho, home of the 46-meter Reclining Buddha and the country’s traditional-massage school, where an hour-long foot or Thai massage runs around 480 baht (about $13). Cross the Chao Phraya on the 5-baht Tha Tien ferry to Wat Arun, then ride an orange-flag Chao Phraya Express boat back downriver at dusk. Evening: graze the stalls of Chinatown (Yaowarat)—try grilled prawns, khao gaeng curry-rice, or mango sticky rice. Insider tip: the express boat is a cheaper, breezier way to see riverside temples than any hop-on tour.

Day 3 — Ayutthaya Ruins Day

Take an early long-distance train from Krung Thep Aphiwat Central Terminal to Ayutthaya, the former Siamese capital and a UNESCO World Heritage Site; the ride is about 1 hour 15 minutes and costs only a few dollars. (The slower ordinary train from Hua Lamphong takes closer to 2 hours.) Rent a bicycle near the station for roughly 50 baht ($1.50) to explore the flat historic island. Don’t miss Wat Mahathat, where a serene stone Buddha head is cradled in bodhi-tree roots—crouch low for the photo, as it is disrespectful to stand above the head. See the three restored chedis of Wat Phra Si Sanphet and the towering prang of Wat Ratchaburana. Combined temple entry runs about 220 baht (roughly $6). Insider tip: go before 9:30am; the tree-root Buddha draws long photo queues by mid-morning and the midday sun is punishing with almost no shade.

Day 4 — Sleeper Train North

Devote the day to Bangkok’s overlooked corners before heading north. Wander Bang Krachao, the jungly “green lung” across the river reached by a 4-baht boat from Klong Toey, and rent a bike through its raised concrete paths and the Bang Nam Pheung floating market (weekends). Or dive into Chatuchak Weekend Market—over 15,000 stalls of textiles, ceramics and street eats—if your dates align. Late afternoon, board the overnight sleeper train #9 from Krung Thep Aphiwat to Chiang Mai, departing around 6:40pm. A second-class air-conditioned lower berth costs roughly 900—1,050 baht (about $26—30) and includes a curtained bed with fresh linens. The 12—13 hour ride is a genuine highlight. Insider tip: book berths days ahead via the D-Ticket site or a station counter—they sell out—and choose a lower bunk for the window and extra space.

Day 5 — Chiang Mai Old City

Arrive into Chiang Mai around dawn and drop bags near the moated Old City. This ancient Lanna capital rewards slow walking. Visit Wat Chedi Luang, whose massive 14th-century stupa was partly toppled by a 1545 earthquake, and the gilded Wat Phra Singh; temple donations are typically 20—50 baht. Take an authentic cooking class (roughly 1,000—1,300 baht, about $30—37) that starts with a morning-market tour to learn galangal, kaffir lime and Thai basil. Cool off with the North’s signature khao soi—a coconut curry noodle soup topped with crispy egg noodles—best hunted near Wat Faham or the Nimman area for around 60—80 baht. Evening: the Sunday Walking Street on Ratchadamnoen (if timed right) or the nightly Chang Phueak night market. Insider tip: songthaews (red shared trucks) charge about 30—40 baht per hop around town—agree the fare before climbing in.

Day 6 — Elephants & Doi Suthep

Book an ethical elephant experience at a well-reviewed sanctuary such as Elephant Nature Park, founded by conservationist Lek Chailert about 60 km north of the city. Reputable places offer feeding, observation and river bathing but never rides or circus tricks; a day visit including hotel pickup runs roughly 2,500—3,500 baht (about $75—95) and books out weeks ahead. In the afternoon, ride a red songthaew or Grab up the mountain to Wat Phra That Doi Suthep, the golden temple overlooking Chiang Mai; the 300-plus naga-flanked staircase leads to the sacred chedi, and foreign entry is about 30—50 baht. Time it for the hazy sunset city view. Insider tip: verify a sanctuary’s welfare policy before booking—”no riding, no bullhooks” is the standard to look for—and avoid outfits that still advertise elephant rides or painting shows.

Day 7 — Fly South to Krabi

Fly from Chiang Mai (CNX) south to Krabi (KBV) on Thai AirAsia or VietJet; the direct hop takes about 2 hours and low-cost fares often run $50—100 one-way if booked ahead. (Note carry-on and checked-bag limits on budget carriers—pay for bags online, as airport fees are steeper.) From Krabi airport, a shared van or metered taxi to the beach town of Ao Nang takes about 30 minutes for roughly 150—350 baht. Spend the afternoon settling in, swimming, and watching the karst-studded sunset from the Ao Nang promenade over a plate of grilled snapper or tom yum goong. Insider tip: Krabi’s Andaman coast has two monsoon-affected seasons—seas are calmest and clearest roughly November through April, while May—October brings warm rain and choppier boat days, so build in schedule flexibility for island trips.

Day 8 — Railay Rock & Sand

Catch a longtail boat from Ao Nang beach to Railay, a stunning peninsula cut off from the mainland by limestone cliffs and reachable only by sea. Boats run roughly 8am—6pm, take about 15 minutes, and cost around 100 baht (about $3) each way—buy your ticket at the beach booth and wait for the boat to fill to nine passengers. Sink your toes into the powdery sand of Railay West, then walk the path to Phra Nang Cave Beach, one of Thailand’s most photographed shores, framed by a fishermen’s shrine. Watch world-class rock climbers scale the cliffs, or book a beginner half-day climb (roughly 1,000—1,500 baht). Insider tip: bring cash—Railay has no ATMs on the beaches and few card readers—and tackle the short, steep, muddy scramble to the Railay Viewpoint and hidden lagoon early before the rock bakes and the trail clogs.

Day 9 — Island-Hop the Andaman

Devote today to the water. Book a longtail or speedboat island-hop to the famous Four Islands—Koh Poda, Chicken Island, Tup Island and Phra Nang—where at low tide a sandbar links several islets into a walkable spit. A shared longtail tour runs roughly 400—600 baht ($12—18); a private longtail for the day is around 2,000—2,500 baht. Snorkel the clear shallows (gear usually included) and pack reef-safe sunscreen. Alternatively, the pricier speedboat run to Hong Island reaches a jade-green enclosed lagoon inside the karsts. Back in Ao Nang, treat yourself to a fresh seafood dinner—point at the day’s catch on ice and have it grilled—with a Chang or Singha at sunset. Insider tip: choose longtail over speedboat if you get seasick and want a quieter, more scenic ride, and always confirm life jackets are aboard before departure.

Day 10 — Last Bites, Fly Home

Enjoy a final slow morning—an early swim, a Thai massage on the sand (about 300—400 baht per hour), and a last bowl of southern-style khao yam rice salad or a fiery gaeng tai pla curry, hallmarks of the spicier southern kitchen. Pick up souvenirs—dried mango, sea-salt scrubs, or hand-dyed batik—before checking out. Depending on your flight home, transfer to Krabi (KBV) for a short domestic hop to Bangkok Suvarnabhumi (BKK) (about 1 hour 20 minutes, often $40—90) to catch your long-haul US connection; leave a generous buffer of at least 3 hours between domestic arrival and international departure. Tipping in Thailand is modest and appreciated but not obligatory—rounding up or leaving 20—50 baht is plenty. Insider tip: keep 300—500 baht in cash for the airport and any last tuk-tuk, and confirm the TDAC and onward-ticket rules haven’t shifted before you travel.
