Begin your journey in Colombo to adjust to the time zone.

A 20-day cultural tour winds through 20 destinations across Sri Lanka, showcasing 8 UNESCO World Heritage sites. The package includes 19 nights in boutique hotels, daily breakfasts, and private AC transport. Travelers visit ancient capitals, wildlife parks, tea plantations, and coastal gems like Galle Fort.
- Days 1-2
Negombo & Kandy
Start your journey in Negombo, located just 20 minutes from the airport. This lets you skip the busy Colombo traffic and settle in smoothly. "The beachside location helps you recover from jet lag while still experiencing local life," one visitor notes. On your second day, visit Pinnawala Elephant Orphanage on your way to Kandy. The drive takes about 3 hours so it's best to leave early before it gets too hot.
- Days 3-5
Cultural Triangle
Make this area your base to explore Sri Lanka's cultural treasures. Visit the Temple of the Sacred Tooth Relic before 8:30 AM to avoid the crowds. The drive to Sigiriya takes about 2.5 hours. Plan your rock fortress climb for early morning or late afternoon when temperatures are cooler. For the Dambulla Cave Temples, wear shoes with good grip since the stone steps can get slippery.
- Days 6-7
Ancient Cities & East Coast
- Days 8-10
Hill Country
The scenic drive to Nuwara Eliya brings cooler weather, so pack some warm clothes as temperatures can drop to 10°C (50°F). According to one traveler: "The 3-hour hike at Horton Plains needs to start by 6 AM - clouds typically roll in by 10 AM, obscuring World's End viewpoint." Book ahead for the scenic train ride from Nanu Oya to Ella in the observation car.
- Days 11-13
Wildlife & Southern Coast
- Days 14-17
South Coast
Travel from Mirissa to Galle for varied coastal experiences. Book whale watching tours (December-April) in the early morning when the sea is calmer. Explore Galle Fort in the morning or evening to avoid the midday heat. One visitor recommends: "Stay inside the fort for evening atmosphere, but book ahead as heritage hotels fill quickly."
- Days 18-20
Colombo & Departure

Wilpattu National Park & Northern Circuit
Start in Negombo and head to Wilpattu National Park for three full days of safaris. "The safari guides' knowledge of animals and plants was exceptional in Wilpattu." Get ready for early morning game drives starting at 6 AM. You'll want warm layers since mornings can be chilly. Plan for 6-8 hour safari days with rest breaks during the hottest parts of the day.
- Days 5-7
Cultural Triangle & Elephant Country
Visit ancient Anuradhapura before moving on to Sigiriya. Stop at Minneriya and Kaudulla National Parks to see the famous elephant gathering.

- Days 8-10
