Which area is right for you
Cat Ba is the largest island in Lan Ha Bay, the quieter southern neighbour of Halong Bay. Most travellers base in Cat Ba town, a strip of hotels and hostels on a narrow bay; others head to the Cat Co beaches a few kilometres away, or to a resort on Lan Ha Bay itself. The town is where the restaurants, bars and boat trips are; the beaches are for swimming and calm.
Cat Ba town
Cat Ba town runs along a curved waterfront with hotels and hostels from roughly $15-60 a night, plus the market, seafood restaurants and the piers for Lan Ha Bay cruises. The bay-front road is the social centre and the best base for first-timers, budget travellers and anyone arranging tours. It is built up and busy in summer, so ask for a quieter seafront room.
Cat Co beaches & Lan Ha Bay
The Cat Co 1-2-3 beaches sit a short walk or ride from town, with a handful of beachfront resorts and bungalows at about $25-70 a night. For more isolation, small resorts and floating homestays on Lan Ha Bay offer kayaking and near-empty water at roughly $40-120 a night. Both suit couples and nature lovers; you trade nightlife and shops for quiet.

Is Cat Ba a good alternative to Halong Bay?
Yes. Cat Ba and Lan Ha Bay offer the same limestone karsts with far fewer boats and crowds, and the island adds a national park, beaches and a real town. Many travellers prefer it for kayaking and a more relaxed pace.

How do I get to Cat Ba from Hanoi?
Bus plus ferry or speedboat from Hanoi takes about 3-4 hours via Hai Phong. Most travellers book a combined bus-and-boat ticket; once on the island, a motorbike or taxi covers the short distances.

April to June and September to November: warm, mostly dry and good for kayaking and hiking. July to August is hot and crowded with Vietnamese holidaymakers; December to March is cool and many boats and beach services are limited.
