Thailand Hike, Bike & Kayak — Self-Launched

Land at Suvarnabhumi or Don Mueang and take the Airport Rail Link + MRT to Hua Lamphong (about £1.20-2) rather than a taxi. Check into a hostel dorm or private room around Yaowarat (Chinatown) — the same neighbourhood as the tour's start hotel but at backpacker prices. Evening: graze the Yaowarat street-food stalls (charcoal-grilled seafood, kuay jab noodles, mango sticky rice) and pick up a Thai SIM/eSIM (~£8 for 15 days of data). Confirm your Bangkok bike tour for tomorrow and buy a Kanchanaburi bus ticket at the counter or via the bus operator's app.

🚌Airport Rail Link + MRT ~£2

🛏Hostel dorm or budget guesthouse, Yaowarat/Chinatown (~£12)

• →Self-guided Yaowarat street-food crawl
• →Buy Thai eSIM/data plan
• →Book Bangkok bike tour and Kanchanaburi bus

Morning: join a small-group Bangkok cycling tour (GetYourGuide/Klook, ~£28-35) that threads through Thonburi's khlong-side lanes, a flower market and backstreet temples — the flat, stop-start riding the operator's own reviewers raved about. Mid-afternoon take the public bus from Sai Tai Mai (Southern) terminal to Kanchanaburi (~2.5-3 hrs, £3-4). Check into a guesthouse along the river and eat at the night market by the bridge.

🚌Public bus Bangkok–Kanchanaburi ~£4

🛏River guesthouse, Kanchanaburi (~£13)

• →Bangkok small-group cycling tour (~£30)
• →Kanchanaburi riverside night market

Early public bus from Kanchanaburi bus station to Erawan National Park (~1.5 hrs, £2-3; park entry ~£7). Hike up all seven tiers of the turquoise falls — go before 10am to beat the crowds and heat, and wear grippy shoes for the slippery upper sections. Back in town in the afternoon, rent a bicycle (~£3/day) and ride out to the River Kwai Bridge and the JEATH War Museum, or take a local songthaew if the heat is brutal.

🚌Public bus to Erawan ~£3 return-ish; bicycle hire ~£3

🛏River guesthouse, Kanchanaburi (~£13)

• →Erawan National Park waterfall hike (entry ~£7)
• →River Kwai Bridge + JEATH War Museum (~£2)
• →Self-guided countryside cycle

A slower travel day: local bus or songthaew to Suphan Buri or Nakhon Pathom, then onward bus to Ayutthaya (~3-4 hrs total, £6-8). Alternatively take the train to Bangkok's Thonburi station and a third-class rail leg north to Ayutthaya (very cheap, £1-2). Settle into a guesthouse inside the old-city island, then rent a bike for sunset at Wat Chaiwatthanaram and dinner at the riverside night market.

🚌Public buses / third-class train ~£7

🛏Guesthouse on the old-city island, Ayutthaya (~£12)

• →Sunset cycle to Wat Chaiwatthanaram (ruins ticket ~£2)
• →Riverside night market

Full morning cycling the UNESCO historical park on a rented bike (£3) — the famous Buddha head in the banyan roots at Wat Mahathat, Wat Phra Si Sanphet and Wat Lokayasutharam's reclining Buddha; a combined ruins pass is ~£5. Late afternoon, ride to Ayutthaya station and board the overnight sleeper to Chiang Mai (~10-11 hrs; second-class fan sleeper ~£15-20 booked on the State Railway of Thailand site or at the station 30-60 days ahead).

🚌Second-class sleeper train Ayutthaya–Chiang Mai ~£18

🛏Overnight sleeper train (berth included in transport cost)

• →Self-guided bike circuit of Ayutthaya Historical Park (~£5 entry + £3 bike)

Arrive early morning, stash your big bag at your Chiang Mai guesthouse and join a 2-night/3-day guided hill-tribe trek booked direct with a Chiang Mai operator or via Klook/GetYourGuide (~£110-140 including homestays, meals and transfers — the closest equivalent to the tour's trek and the one place a local guide is genuinely worth paying for). Transfer to the trailhead and walk 4-6 hrs through forest to Baan Pha Lho, a Karen/Lahu village. Dinner cooked by your host family; optional herbal sauna.

🚌Shared songthaew to trailhead (included in trek)

🛏Village homestay, Baan Pha Lho (included in trek price)

• →Hill-tribe trek day 1 (~5 hrs walking)
• →Village homestay dinner
• →Traditional herbal sauna (small extra)

A full trekking day of 6-8 hrs over ridges and through bamboo forest, with a picnic lunch packed by your hosts. Sections are steep and slick after rain — trekking poles or a sturdy stick help. Arrive at Ban Mae Ma homestay in the late afternoon, wash in the village stream, and eat a home-cooked dinner. Carry only a 30-35 L daypack; your main luggage stays in Chiang Mai.

🚌On foot

🛏Village homestay, Ban Mae Ma (included in trek price)

• →Hill-tribe trek day 2 (~7 hrs walking)
• →Jungle picnic lunch
• →Village homestay evening

A shorter morning walk out of the hills (3-4 hrs) with a packed lunch, then a shared songthaew back to Chiang Mai by mid-afternoon. Check into a guesthouse in the old city, reclaim your luggage, and spend the evening at the Sunday Walking Street or Warorot Market if it's the right night — otherwise the Night Bazaar and a khao soi dinner.

🚌Shared songthaew return (included in trek)

🛏Old-city guesthouse, Chiang Mai (~£13)

• →Hill-tribe trek day 3 (~4 hrs walking)
• →Warorot Market / night market food crawl

Early morning at Wat Phra That Doi Suthep (songthaew up the mountain, ~£2 return) or a wander through the old-city temples before checkout. Midday budget flight Chiang Mai–Krabi on AirAsia/Nok/Thai Vietjet (~£40-60 booked 4-8 weeks ahead; the 13-hr train-and-bus alternative saves money but burns a day). Shared van or Airport Bus from Krabi airport to Ao Nang (~£4). Book tomorrow's four-island longtail tour with a beachfront agent.

🚌Budget flight ~£50 + airport van ~£4

🛏Guesthouse or budget hotel, Ao Nang (~£15)

• →Doi Suthep temple (songthaew ~£2)
• →Book four-island longtail tour

Join a shared four-islands longtail boat day (Klook/local agent, ~£25-30 including lunch, mask and snorkel) covering Ko Poda, Ko Gai, Ko Tub and Phra Nang Cave Beach — the operator's Ko Hong/Ko La Ding snorkelling day in self-booked form. Bring a dry bag (a reviewer's top tip), reef-safe sunscreen and cash for the national park fee (~£8). Back by late afternoon for sunset beers on Ao Nang beach.

🚌Longtail boat (included in tour price)

Public songthaew or local bus from Ao Nang to Krabi town (~£1.50), then onward transport toward Laem Sak (~1.5 hrs, ~£3; shared vans run from Krabi's bus terminal — ask your guesthouse to call ahead). Check into a simple family-run bungalow, then paddle the Bo Tor mangrove channels by sea kayak on a locally arranged half-day (~£15-20), finishing with a walk through the village and a batik-making session with a local artisan (~£8).

🚌Songthaew + shared van ~£5

🛏Family bungalow, Laem Sak (~£11)

• →Sea kayak Bo Tor mangroves (~£18)
• →Batik-making class (~£8)
• →Village walk

Full-day sea-kayaking trip from Laem Sak out to the limestone islands of Ko Laem and Ko Chong Lat (~£30-35 with a local guide, picnic lunch on a floating platform). Expect mangroves, hidden hongs and quiet beaches with almost no other tourists. Note that Laem Sak itself has no swimmable beach — the kayaking is the whole point of being here, so skip the free half-days the group tour builds in and paddle instead.

🚌Kayak and longtail support (included in tour)

🛏Family bungalow, Laem Sak (~£11)

• →Full-day sea kayaking Ko Laem & Ko Chong Lat (~£33)

Morning shared van from Laem Sak to Krabi or Surat Thani, then an overnight sleeper train north to Bangkok (~11-12 hrs, second-class sleeper ~£18-22; book on the SRT site) — or a budget flight Krabi–Don Mueang (~£30-40) if you'd rather sleep in a bed. Buy snacks and water for the journey and confirm your airport transfer for tomorrow.

🚌Airport Rail Link ~£1.20
