Self-Launched Coast to Caves Adventure in Vietnam

Catch the airport bus (86 from Noi Bai Airport to the Old Quarter, ~£1) or a metered taxi (~£7-10) to your hostel or budget hotel near Hoan Kiem Lake. Once checked in, dive straight into the Old Quarter's maze of narrow streets — grab a bia hoi (draught beer, ~20p a glass) at the famous Bia Hoi Corner on Ta Hien Street and soak up the chaos. For dinner, try bun cha or pho at one of the countless street stalls. An easy first evening to settle in, meet fellow travellers at your hostel, and plan ahead.

Rise early for a bowl of pho and a glass of egg coffee (ca phe trung) at Cafe Dinh or Giang Cafe in the Old Quarter (~£2). Then make your way to Tuan Chau Island — book a shared minibus transfer from the Old Quarter (~£5-8, bookable via your hostel or GetYourGuide). Board a 2-day/1-night junk cruise into Lan Ha Bay. Lan Ha Bay sits just south of Halong Bay, is less crowded, and offers the same stunning limestone karst scenery. Budget junk cruises (e.g. Bhaya Cruises, Paradise Cruises entry tier, or Cat Ba Ventures) include meals, kayaking, and a cave visit. Book direct online in advance for best rates.

Morning kayaking is usually included in your cruise, often through the Tra Bau area — the same dramatic filming location used for Kong: Skull Island. Disembark at Gia Luan port on Cat Ba Island by late morning. From there, take a local bus or taxi (~£2) to Cat Ba town. Consider booking a half-day guided hike in Cat Ba National Park through the park entrance (~£3 entry fee) up to Ngu Lam Peak and down through Trung Trang Cave. Alternatively, book via GetYourGuide. Settle into your Cat Ba guesthouse and head to a rooftop bar for sunset views, then pick a seafood restaurant on the harbour for dinner.

Arrange a morning boat trip to Viet Hai Village (~£8-12 return by local boat, bookable via your guesthouse) — a peaceful, largely car-free village ideal for a gentle cycle. Bike hire is available on arrival (~£3). Return to Cat Ba, then take the ferry back to the mainland and a shared bus or limousine van back to Hanoi (~£6-10, book via Cat Ba Express or your hostel). Arrive at Hanoi Ga station in the evening for your overnight sleeper train to Dong Hoi. Book SE trains (Reunification Express) in advance via Baolau.com or Vietnam Railways (12Go.asia) — a 4-berth soft sleeper is ~£15-20.

Book a guided Son River kayaking tour through a local operator such as Phong Nha Farmstay or Oxalis Adventure — these half-day tours paddle deep into the national park past limestone karsts, villages and jungle riverbanks (~£15-25pp). In the afternoon, check into a guesthouse or ecolodge near the park. If budget allows, the Phong Nha Farmstay is a beloved traveller favourite with a great social vibe (~£18-30). In the evening, arrange a torchlit night kayaking session via your accommodation — a magical, low-key experience on the river.

This is the wildest day of the trip and requires booking in advance. Oxalis Adventure is the premier operator for backcountry caving and jungle camping in Phong Nha-Ke Bang, and their multi-day jungle and cave packages cover Elephant Cave, Ma Da Valley, and wild camping at Ma Da Lake with all gear, guides, meals and porter service included. Book their 2D/1N 'Tu Lan Cave' or 'Hang Va' expedition for a comparable experience (~£120-180pp for 2 days, all-inclusive). This is a must-book-in-advance, non-negotiable specialist activity — Oxalis is the only licensed operator for most of the caves in the backcountry. Your porters carry camping gear; you carry a daypack.

Wake to a morning swim in the deserted lake, then begin the hike back through dense jungle to Tra Ang Cave — a highlight of the entire trip. You'll swim its extraordinary 600m passage by headlamp (wetsuits and life jackets provided by Oxalis). This is the kind of experience you genuinely cannot replicate independently — Oxalis guides are essential for safety in these remote cave systems. Lunch is taken in the wilderness before hiking the Tra Ang River Trail back to the trailhead. Return to your Phong Nha guesthouse in the afternoon for hot showers. In the evening, enjoy a local Vietnamese barbecue dinner at a restaurant in Phong Nha village (~£5-8).

The flat roads along the Son River are perfect for an unhurried spin past rice paddies and local markets. Return bikes and grab lunch at a local spot (~£2-3). Then arrange a shared taxi or private car hire to drive north to the coast near Ha Tinh / Thach Ha (~2.5hrs, ~£12-18 by shared taxi arranged via your guesthouse or an app like Grab). Check into a beachside guesthouse on the South China Sea and spend the rest of the afternoon swimming and watching the sunset.

The most comfortable option is a sleeper bus from the nearest town to Hanoi (~£10-14, ~6hrs, book via Phuong Trang/FUTA Bus or Bookaway.com), or a combination of local bus to Dong Hoi and then a train. Alternatively, book a private car transfer if travelling as a small group (~£15-25pp split). Arrive in Hanoi in the early evening, check back into your Old Quarter hotel, and head out for a farewell dinner with anyone you've met along the way.
