North Bay Island is a small, wooded island on the north side of Port Blair harbour, known for a red-and-white lighthouse that appears on the Indian twenty-rupee note. Its sheltered bay holds a patch of coral reef that is easy to reach, and a collection of activities that make it a favourite with families and first-time visitors.
What you can do
- Snorkelling. Shallow water and calm conditions make it easy for beginners. A guide takes you out to the reef, where you can see colourful coral and fish.
- Glass-bottom boat ride. A boat with a transparent floor lets you view coral without getting wet. It is a good option for children and non-swimmers.
- Sea walk. You wear a helmet connected to an air supply and walk on the seabed with a guide. No swimming skills are needed.
- Scuba dive. Introductory dives are offered, though most people prefer Havelock for diving.
- Beach time. A small strip of sand for relaxing, with shade and stalls.
- The lighthouse. A photo stop, sometimes with a climb for views.
The coral and its condition
The reef at North Bay has suffered over the years from storms and visitor pressure. It still has hard corals, sea fans and reef fish, but it is not as vibrant as the best Andaman sites. It is a good introduction, and children are often delighted. If you want a more pristine reef, consider Neil, Havelock or the Mahatma Gandhi Marine National Park islands.
Safety and etiquette
- Wear a life jacket for snorkelling if you are not a strong swimmer.
- Do not touch or stand on coral.
- Follow the guide's instructions at all times.
- Check that the sea walk equipment is clean and properly fitted.
- Avoid activities if you have a cold, ear problems or heart conditions.
- Keep children supervised.
- Do not feed fish.
How to get there
Boats leave from the Phoenix Bay jetty in Port Blair and take about 20 to 30 minutes. Tickets are bought at the jetty or through tour operators. In peak season, boats fill up, so go early. Bring photo ID.
Best time to visit
November to April is the best period, with calmer water and better visibility. Early morning is best. In the monsoon, trips may be cancelled.
Practical tips
- Wear swimwear under your clothes, and bring a towel and a change of clothes.
- Use reef-safe sunscreen, and wear a hat.
- Carry cash, water and snacks.
- Protect cameras and phones in waterproof pouches.
- Compare prices for activities at the island, and agree before you start.
- Take your waste back with you.
Who it suits
Families with children, first-time snorkellers, and anyone who wants a short, easy water day. If you are an experienced diver, you will find more interest elsewhere.
