Short answer
Krabi works well with children who can handle a short boat ride, sun and a beach, and less well with babies and toddlers. Our Krabi 4 Islands speedboat day takes children from about 4 years and is back at about 2:00 pm; our 7 Islands sunset tour does not recommend infants under 2 and returns at about 7:30 to 8:00 pm. The park fee for a child is 100 baht on both. Plan for sun protection, a close eye on children in the water and early starts.
Boat days with children: the ages we can take
Our Krabi 4 Islands speedboat tour, from $35 per person, suits children from about 4 years: the boat rides are short and the beaches calm. It is not recommended for infants under 4, pregnant women or people with back or neck problems. The Hong Islands day, from $40, has the same limits, but it is longer, with a return at about 3:30 pm instead of about 2:00 pm. The national park fee for a child is 100 baht on the 4 Islands and 150 on the Hong Islands, in cash at check-in.
Our Krabi 7 Islands sunset tour, from $40, takes children, but infants under 2 are not recommended. It runs on a longtail boat, and young children and older guests may find it hard to climb in from the beach. The day is long, with a return to your hotel at about 7:30 to 8:00 pm, and it ends with a swim of about 30 minutes in the dark with plankton. Tell us your children's ages when you book.
Beaches that suit small children
Poda is the easiest island beach for families. Thai Holiday Guide says the main beach is sheltered and shallow enough for young children and the boat ride is short, though there is no shade structure beyond a few trees, so bring your own umbrella if you stay more than an hour. It says the beach is busiest from 10:00 to 14:00. Our Poda Island guide covers the fee and the best times.
Be more careful at Phra Nang and Nopparat Thara. Thai Holiday Guide says the sand at Phra Nang narrows at high tide, and Wikivoyage says Nopparat Thara narrows too and that you should ask locals about jellyfish before swimming. Wikivoyage also says the trail to Pai Plong Beach, 10 to 15 minutes and steep in places, is best avoided by small children. See our Phra Nang Cave Beach guide for tides.
Sun and heat: what the NHS says to do
Andaman Wave Master gives temperatures of 25 to 30 degrees Celsius in the cool season from November to February and 30 to 38 degrees in the hot season from March to June, so the sun is strong all year. The NHS says children's skin is much more sensitive than adult skin, and recommends a sunscreen of at least SPF 30 with at least 4-star UVA protection, reapplied about every 2 hours and straight after being in water.
The NHS also advises keeping babies under 6 months out of direct strong sunlight, and suggests a wide-brimmed hat and shade. Thailand's marine national parks ban sunscreens with four chemicals, oxybenzone, octinoxate, 4-methylbenzylidene camphor and butylparaben, with a fine of up to 100,000 baht, according to a 2021 report. Check the label before you pack, and see our reef-safe sunscreen guide.
Water safety: keep an adult within reach
The World Health Organization's drowning fact sheet, dated 1 May 2026, says children under 5 account for nearly a quarter of all drowning deaths, and that the risk rises when children are in water outside active adult supervision. A life jacket helps, and our boat tours include one for each guest, but it does not replace an adult within reach of each young child at every stop.
Ask us about child sizes when you book, because the details we hold do not list sizes of mask or life jacket. Fins are not provided, and jellyfish appear in some seasons, when long swimwear and water shoes help. On our sunset tour the plankton swim is in the dark, so decide beforehand whether your child will be comfortable, and tell us if you are unsure.
Land days: what to skip with toddlers
The Tiger Cave Temple stairway has handrails and rest platforms, according to Thai Holiday Guide, but Wikipedia says some risers are more than 30 cm high, and the climb takes most people 30 to 60 minutes up. That is a lot for a toddler; our Tiger Cave Temple guide has the details. At the Emerald Pool, Thai Holiday Guide advises water shoes for the uneven pool floor, and entry is 400 baht for foreign adults and 200 for children.
Easier family options are the Krabi Walking Street, which Thai Holiday Guide calls low-key and pedestrian, with a stage and no real bar scene, though very crowded on Saturday nights. For elephants, Phuket 101 advises researching carefully and avoiding places that offer rides. See our night market guide and Emerald Pool guide.
Boats, seasickness and the best months for families
Andaman Wave Master says the sea is calmest from November to February, while from July to October offshore conditions can be choppy and schedules adjust for safety. For children who feel sick on boats, the NHS advises sitting in the middle of the boat, looking at a fixed point such as the horizon, distracting them with talk or songs and avoiding heavy meals before travel. It says dissolvable tablets are available for children, and that a pharmacist can recommend treatment.
Buy any remedy before the trip and read the age on the pack. Our seasickness guide has more. On our tours, if the sea is unsafe the operator moves the trip to another date or refunds it. In the rainy months Wikivoyage says many places in Ao Nang shut or restrict their hours, so check before you go; our Krabi in the rainy season guide covers the weather.
Where to base a family: Ao Nang or Railay
Ao Nang is the easier base with children. Wikivoyage calls it the most Westernised beach in Krabi, with easy transport, many restaurants and tour agencies, and Phuket 101 says it is a small town where many hotels are within walking distance of the beach, the shops and the restaurants. It is about a half-hour drive, 24 km, from the airport, according to Phuket 101; our airport guide covers the transfer.
Railay is quieter but harder with luggage. Wikivoyage says there are no cars and the bumpy paths make even bicycles impractical, so think twice about a pushchair. Boats from Ao Nang have no pier, and you may wade ashore with your bags. Wikivoyage adds that Railay East is a mangrove shore, not good for swimming, so choose the west side. Our Ao Nang or Railay guide compares the two.
Practical checklist
- Send each child's age with your WhatsApp booking, and ask about child life jackets.
- Pack SPF 30 sunscreen with 4-star UVA protection that is free of the four banned chemicals, plus hats.

- Bring cash for the child park fee: 100 baht on the 4 Islands and 7 Islands tours.
- Buy a children's seasickness remedy from a pharmacy before the boat day.
- Keep the Tiger Cave Temple and slippery pools for older children.
