One of the things that makes living in Phuket genuinely extraordinary is the access to protected natural environments within a short drive. You're surrounded by national parks — some of them on the island itself, some a short drive up the coast, some offshore. The Similan Islands are 60km away. Ao Phang Nga National Park is less than an hour north. Khao Sok National Park, with one of the world's oldest rainforests and a surreal lake system, is two hours away and completely worth a weekend visit.
This guide covers the national parks accessible from Phuket, what's in each, how to get there, and — because it matters — the entry fee system and when each is worth visiting.

Sirinat National Park — Phuket's Own National Park
Sirinat National Park covers the northwest coast of Phuket itself — the long beaches of Mai Khao (Phuket's longest beach at approximately 17km), Nai Yang, and Nai Thon, plus the mangrove areas and inland buffer zones along the northwest coast. If you live in Bang Tao, Surin, or Cherng Talay, this national park is effectively on your doorstep.
The most notable feature of Sirinat for Phuket residents is Mai Khao beach, which is one of the few remaining sea turtle nesting beaches on Phuket. Between November and February, leatherback and green sea turtles come ashore at night to nest. The Department of National Parks runs conservation programmes; accessing the beach during nesting season after dark is strictly controlled, but the beach is otherwise open daily.
Nai Yang beach within the park is calmer and more sheltered than most west coast Phuket beaches, with shallow reef areas popular for snorkelling. There's a small national park visitor centre near Nai Yang. Day use of the beach areas is generally free for residents; formal national park activities (snorkelling tours, guided mangrove walks) have fees.
Ao Phang Nga National Park
Ao Phang Nga National Marine Park covers the famous limestone karst landscape of Phang Nga Bay — the distinctive tall island formations, sea caves, mangrove channels, and the iconic James Bond Island (Khao Phing Kan). The park is approximately 60km from Phuket Town, reached via the Tha Don pier in Phang Nga province (about 45 minutes by car from central Phuket).
The park is best experienced by longtail boat or kayak through the sea caves (hongs — Thai for interior lagoons accessible only by paddling through low sea caves at certain tides) and along the mangrove channels. Several operators from Phuket offer guided tours; independent access is also possible by hiring a longtail from the Tha Don pier.
The most rewarding experience in Ao Phang Nga is sea kayaking through the hongs — hollow limestone islands accessible through narrow cave passages — which reveals enclosed lagoons with wildlife and vertical limestone walls. This requires either a guided tour or expert navigation and is not recommended for solo paddlers without experience in tidal calculations.
James Bond Island (where 1974's The Man with the Golden Gun was filmed) is the most-visited spot in the bay and consequently the most crowded. The geology is spectacular; the tourist crowds are significant during high season. Visit early morning or go to lesser-visited areas instead.
Khao Lak-Lam Ru National Park
Khao Lak-Lam Ru National Park sits along the coast approximately 70km north of Phuket, adjacent to the Khao Lak resort area of Phang Nga province. The park covers coastal rainforest, streams, waterfalls, and a stretch of coast that's significantly less developed than Phuket's main beaches.
The park is a good option for hiking — several trails lead through coastal forest with decent wildlife possibilities, including hornbills and various forest birds. The coastal section has reef areas accessible for snorkelling at the right tide conditions. A straightforward drive from Phuket via Highway 4 makes this a solid half-day trip, especially for Bang Tao and Cherng Talay area residents who are closest to the northern coast route.
Mu Ko Similan National Marine Park
This is the one that gets mentioned on international "world's best" lists. The Similan Islands are 9 main islands 60km northwest of Phuket in the Andaman Sea, forming one of Asia's premier marine ecosystems. The combination of granite boulder formations underwater, exceptional visibility, rich coral systems, and regular large marine animal encounters (whale sharks, manta rays, reef sharks, sea turtles) makes the Similans genuinely world-class diving territory.
The park is only open November to May — it closes for the monsoon season. Day trips from Phuket take approximately 2.5–3 hours by speedboat from Khaolak (90 minutes) or Chalong Pier on Phuket (2.5+ hours). The quality of a Similan day trip is inferior to a liveaboard because you lose 5+ hours to transit; the Similan experience is significantly better on a multi-day liveaboard trip departing from Chalong or Ao Po.
For non-divers, snorkelling at the Similans is genuinely exceptional — the shallow reef areas around the islands are accessible and rich. Day trip snorkelling packages from Khaolak are the most popular option for non-diving visitors.

Khao Sok National Park — The Weekend Trip Worth Doing
Khao Sok is approximately 100km northeast of Phuket — about 2 hours by car via Highway 401. It's one of the world's oldest tropical rainforests (estimated at 160 million years, older than the Amazon), and it surrounds Cheow Lan Lake — a stunning 165-square-kilometre reservoir with dramatic limestone karsts rising vertically from the water, dotted with floating raft houses where you can stay overnight.
From experience: Khao Sok is one of those places where a Phuket expat says "I really should go" for two years and then goes and immediately wonders why they waited so long. The morning mist on Cheow Lan Lake is extraordinary. Gibbons calling at dawn from the forest canopy is one of the more memorable sound experiences you'll have in Thailand. And the floating raft house accommodation, while basic, has a particular magic that's completely unlike anything else accessible from Phuket.
A practical two-night itinerary: arrive evening, overnight raft house on Cheow Lan Lake (book in advance — the good ones fill up), sunrise on the lake, optional tube or kayak on the lake during the day, drive back to Phuket on day three. An organised Khao Sok overnight package from a Phuket tour operator typically runs 3,500–6,000 THB per person including transport, accommodation, and most activities.
