Best months: October to April for cooler, drier weather and clearer skies. Summer (May–August) can be hot, humid and rainy but is fine for swimming and island beach activities.

Tropical climate with a warm, humid summer and a cooler, drier season in winter. Expect heavy rain and occasional storms in the monsoon months (late summer). Temperatures range roughly from mild 15–25°C in the cooler season to 25–35°C in summer.

The park has an official entry system; fees and opening hours can vary. Expect a modest entrance fee plus additional charges for guided treks or protected-area zoning. Typical park visiting hours are during daylight (roughly early morning to late afternoon). Check current rates and permitted trail access at the park office in Cat Ba Town before entering.

Cat Ba Island is accessible by ferry/hydrofoil from Hai Phong and Ha Long City (fast boats run from both). From Hanoi, travelers commonly take a bus or car to Hai Phong or Ha Long then a boat to Cat Ba. Nearest airports are Cat Bi (Hai Phong, about 30–60 minutes by road to the boat terminals) and Noi Bai (Hanoi, ~2–3 hours to ferry connections). Once on Cat Ba Island, the park is reached by road from Cat Ba Town; some trails require moderate fitness and are uneven—expect dirt paths, steps and rocky sections.

1–2 days to explore main trails and viewpoints; 2–4 days if combining park trekking with Lan Ha Bay kayaking, beaches and relaxed village visits.

Lightweight breathable clothing, sturdy hiking shoes, sun protection (hat, sunscreen), rain jacket (especially in wet season), insect repellent and a small first-aid kit. Bring binoculars for birding and a refillable water bottle.

Fresh seafood is the island specialty—try local grilled fish, squid and seafood hotpots in Cat Ba Town. Souvenirs include small handicrafts, dried seafood products and locally made items from island vendors. Support community-based products where possible.
