For comfortable planning, it's recommended to book a tour to the Similan Islands at least 3 days before your desired trip date. This is the minimum time for a guaranteed spot. However, during peak season (December-February), especially during holidays (New Year, Chinese New Year), spots fill up very quickly, and it's better to book 1-2 weeks in advance. The number of tourists in the national park is limited daily to protect the ecosystem, so when the quota is full, new bookings are not accepted. Early booking also allows you to choose a convenient date and get better transfer from your hotel.
January, February, and March are absolutely the best months to visit the Similan Islands with ideal weather conditions. Average air temperature stays stable around +30-32°C during the day, the sea warms up to a comfortable +27-28°C. The sky is predominantly clear and sunny, rain is virtually excluded (probability less than 5%). The sea is calm with minimal waves, making swimming and snorkeling maximally comfortable. Underwater visibility reaches 30-40 meters - ideal for observing marine life. Humidity is moderate, around 70-75%. This is peak tourist season, so book in advance.
The best time to visit the Similan Islands is from November to April. This is the high season when the sea is calm, underwater visibility is excellent (up to 30-40 meters), and the weather is consistently sunny. Peak months are January, February, and March, when there are virtually no rains or storms. During this time, air temperature is around +30°C, water warms up to +28°C. November and April are transitional months, also good for trips, but with a slight chance of brief rains.
From Phuket to the Similan Islands, the journey takes approximately 1.5 hours by speedboat. First, you'll be picked up from your hotel and brought to the pier (about 1-1.5 hours by bus), then by boat to the islands. Total time from hotel to islands is about 3-3.5 hours including transfer. Return journey is similar. The boats are modern and comfortable, with comfortable seating and sun protection, making the trip enjoyable.
No, there is no Wi-Fi on the Similan Islands and no internet or mobile connection at all. The islands are located 70 kilometers from the mainland in the open sea, where there is no mobile operator coverage. This is a completely autonomous national park zone without electricity and modern infrastructure. See this as an opportunity for a digital detox and complete immersion in nature! You can enjoy the beauty of the underwater world and beaches without distraction from messages and calls. Upon returning to the mainland, connection will be restored.
No, it's impossible to pay by bank card on the Similan Islands. The islands are a protected national park without developed tourist infrastructure, electricity, or internet. Therefore, card payment terminals are not available. If you want to buy souvenirs at the small shop on the islands or leave tips for the crew and guide, bring cash Thai baht with you. Usually 500-1000 baht is sufficient. All main services (transfer, meals, equipment) are already included in the tour price that you pay when booking.
Yes, visiting the Similan Islands with children is quite possible and safe! It's recommended to bring children from 4 years old, as younger ones may find the long boat ride difficult. Special children's life jackets in appropriate sizes are provided for all children without exception. The islands have gentle beaches where children can swim safely. Snorkeling with children is conducted in shallow water under constant supervision of instructors. Many families with children have a wonderful time observing colorful fish in the crystal-clear water.
Medical travel insurance for visiting the Similan Islands is not mandatory, but we strongly recommend obtaining it. The tour price already includes basic national park insurance that covers accidents during the tour. However, it has limited coverage. Comprehensive travel insurance will protect you from unforeseen medical expenses, cover assistance for injuries, coral cuts, sunburns, seasickness, and other cases. It may also include evacuation and repatriation, which is especially important on remote islands.
If you're prone to seasickness, there are several ways to ease the condition. All boats have seasickness tablets on board that can be obtained free from the crew - it's best to take them 30-60 minutes before departure. Choose a seat in the center of the boat where motion is felt the least. Avoid a heavy breakfast before the trip, but don't go on an empty stomach - a light snack is ideal. Look at the horizon, not at waves or your phone. Fresh air helps - try to stay on the open deck. The journey to the islands takes only 1.5 hours, so any discomfort will be temporary.
The Similan Islands and Phi Phi Islands are two completely different destinations, each with its own advantages. Choose the Similans if your priority is world-class snorkeling and diving with crystal-clear water, incredible underwater world, healthy coral reefs, and pristine nature. The Similans are a national park with no hotels or bars, but with solitude and pristine beauty. Choose Phi Phi if you want famous photogenic beaches (like Maya Bay), more opportunities for beach relaxation, cafes, and entertainment. Ideally - visit both places to get a complete picture of the beauty of the Andaman Sea!
