Sri Lanka Travel Guide: Beaches, Kandy, Sigiriya & Day Trips

Sri Lanka is small on the map and enormous in reality. In a single week you can drift down a mangrove river at dawn, climb a 1,500-year-old rock fortress by mid-morning, and be barefoot on a south-coast beach by sunset. This is a slow-travel guide to doing it well — with honest notes on the south west of Sri Lanka for beach holidays, where to go in Sri Lanka in December, the eternal Kandy or Sigiriya debate, and the best one-day trip places in Sri Lanka to slot in between.

South West Sri Lanka for beach holidays

If your idea of a Sri Lankan holiday is warm sand, calm mornings, and a fresh king-coconut before breakfast, the south-west coast is where you want to be from roughly November to April. This stretch — Bentota, Beruwala, Hikkaduwa, Unawatuna, Weligama, Mirissa, Tangalle — catches the dry monsoon window and is the most reliable beach belt in the country during the northern-hemisphere winter.

Bentota — the classic resort choice, wide beach, glassy lagoon, easy from the airport.
Unawatuna & Dalawella — swimmable bays, a short tuk-tuk from Galle Fort.
Weligama & Mirissa — surf, whale watching (Dec–April), palm-fringed coves.
Tangalle — quieter, wilder, better for boutique stays than swimming.

For curated stays and tailor-made south-coast itineraries, the team at Serendipity's destinations page covers each town in detail. See also our own destinations overview for a shorter, opinionated shortlist.

Where to go in Sri Lanka in December

December is peak season for good reason: the south and west are dry, the hill country is crisp and green, and the Cultural Triangle is warm but manageable. A classic two-week December route looks like this:

Days 1–3: Negombo → Sigiriya & Dambulla (Cultural Triangle).
Days 4–6: Kandy — Temple of the Tooth, botanical gardens, a cooking class.
Days 7–9: Kandy to Nuwara Eliya by train, tea country, Horton Plains at dawn.
Days 10–14: South-west coast — Bentota, Galle, Mirissa.

Avoid the east coast (Trincomalee, Arugam Bay) in December — that's the wet side of the year. For a deeper look at the ancient cities you'll pass through, read our complete Cultural Triangle guide.

Where to go: Kandy or Sigiriya?

The honest answer is both — they're only about 2.5 hours apart and they do completely different things.

Choose Sigiriya if…

You want ancient Sri Lanka: the rock fortress at sunrise, the Dambulla cave temples, a jeep safari in Minneriya or Kaudulla for wild elephants, and village-style stays surrounded by paddy fields.

Choose Kandy if…

You want living culture: the Temple of the Sacred Tooth Relic, the evening puja, Peradeniya gardens, and a base for the train to the hill country. Kandy is a real working city with better food and more nightlife than Sigiriya.

If you only have one night, pick Sigiriya for the landscape. If you have two, do both. Full multi-day itineraries are available through Serendipity's tour packages.

Temple of the Tooth dress code

The Sri Dalada Maligawa in Kandy is one of the most sacred Buddhist sites in the world, and the dress code is enforced at the entrance — not as a suggestion.

Shoulders covered. No vests, no tank tops, no sheer fabrics.
Knees covered. Long trousers, long skirts, or a sarong tied over shorts. Sarongs are sold outside for a few hundred rupees.
Shoes off before entering the temple complex — bring socks if the stone floor at midday worries you.
Hats off inside. Never pose with your back to a Buddha statue for photos.

Aim for the evening puja (around 6:30pm) — the drumming, the queues of white-clad pilgrims, and the opening of the inner shrine are the real experience.

Bentota river safari

The Bentota Ganga is one of the most underrated half-days on the south-west coast. A small boat winds up through mangrove tunnels into a lagoon studded with tiny islands — one of them, Monkey Island, is exactly what it sounds like.

What you can expect to see:

Water monitors sunning on branches (much friendlier than they look).
Kingfishers, sea eagles, egrets, and if you're lucky, a mangrove crocodile.
Fish therapy stops where tiny fish nibble your feet in the shallows.
Cinnamon Island — a working cinnamon farm where a family will show you how the bark is peeled and rolled.

Go early (7–9am) for the best light and the coolest air. Two hours is enough; three is generous. Serendipity can arrange this as part of a south-coast package or as a standalone half-day.

One day trip places in Sri Lanka

If you're based on the west or south coast and only have a day to spare, these are the trips actually worth the early alarm:

Galle Fort — Dutch ramparts, cafés, and the sunset walk on the walls.
Bentota river safari + Madu Ganga — see above.
Sinharaja rainforest — a guided walk in Sri Lanka's last true lowland jungle.
Udawalawe National Park — the most reliable place in the country to see wild elephants.
Colombo food tour — a proper eating walk through Pettah and Slave Island.
Kandy from Colombo — long but doable; the Temple of the Tooth and a lake walk in a single day.

For custom day trips with a driver-guide, Serendipity's team puts together bespoke routes; you can also see our contact page for recommendations.

Kandy to Nuwara Eliya: the train you've seen in every photo

The Kandy to Nuwara Eliya (technically Nanu Oya station) train is the one with the open doors, the tea plantations, and the arm-out-of-the-window shot. It's worth the hype — but a few things worth knowing:

Book 2nd or 3rd class reserved for the best views. 1st class is air-conditioned with sealed windows — pretty, but you can't feel it.
Book early. Reserved seats open 30 days ahead and sell out in hours in December–February.
Journey time: about 4 hours Kandy → Nanu Oya, then a 40-minute drive up to Nuwara Eliya town.
Best side: sit on the right leaving Kandy for the deepest tea-country views.
Bring: a fleece (it gets cold above 1,500m), snacks, and cash for the tea and vadai sellers who walk the carriages.

Once you're in Nuwara Eliya, the classic add-ons are a tea-factory tour, Horton Plains at sunrise for World's End, and a night at one of the colonial hill-country hotels. For full hill-country itineraries, see Serendipity's tour packages.

Planning your trip

The trick with Sri Lanka is not trying to do everything. Pick two anchor regions — Cultural Triangle + south-west coast is the perfect December pairing — and give each of them enough time to breathe. If you want help stitching it together, Serendipity Private Tours arranges private driver-guide trips across the island, and you can contact them here for a quote.
