When visiting Colombo, a trip to Gangaramaya Temple is a must. One of the city's most famous landmarks, this temple is a living testament to Sri Lankan Buddhism and a centre of learning and worship. Visitors can marvel at the stunning architecture and intricate carvings of the temple's buildings, stroll through the tranquil gardens, and observe the daily rituals of the resident monks. As with all religious sites in Sri Lanka, visitors are expected to dress appropriately, which means covering their shoulders and knees. It's also important to remove shoes before entering the temple and to be respectful of the monks and other visitors. The temple is open every day from 6 a.m. to 10 p.m., and admission is free, but donations are welcome to support the temple's ongoing restoration and conservation efforts.
