When visiting Wat Mahathat, it’s important to dress modestly, as the temple is still considered a sacred site. While exploring, be mindful of the ruins and avoid climbing on the ancient structures to preserve their integrity. The temple is typically open daily, but check the hours of operation in advance. There is a small entrance fee, which helps maintain the historical site. The area can get hot during midday, so it’s a good idea to visit early in the morning or late afternoon to avoid the heat. The temple is one of the busiest attractions in Ayutthaya, so expect crowds, especially during peak tourist seasons.

Wat Mahathat is located within the Ayutthaya Historical Park and is easily accessible from the center of Ayutthaya. It is a short walk from other notable temples and attractions in the park, such as Wat Phra Si Sanphet and the Grand Palace. If you’re coming from Bangkok, you can reach Ayutthaya by train, bus, or private car, with the temple being a short walk or tuk-tuk ride from the Ayutthaya Railway Station. Once in Ayutthaya, cycling is a popular way to explore the historical park, as the temple is located near many other ruins. For those seeking more comfort, tuk-tuks are readily available for hire.

The best time to visit Wat Mahathat is during the cooler months, from November to February, when temperatures are more pleasant for exploring outdoor sites. Early mornings are ideal, as the temple is less crowded, and the morning light is perfect for photography. If you're visiting during the hotter months (March to June), it’s advisable to bring water, sunscreen, and a hat to stay cool. Although Wat Mahathat is an incredible sight year-round, avoiding the midday heat and large crowds will enhance your experience.

Wat Mahathat is a central attraction for anyone visiting the Historic City of Ayutthaya. After exploring the temple, consider taking a boat tour around the city’s ancient island, which will give you a unique perspective of the temple ruins from the river. You can also visit nearby temples such as Wat Phra Si Sanphet and Wat Chaiwatthanaram, both significant sites in Ayutthaya's history. For a deeper dive into the city’s past, take time to explore the Ayutthaya Historical Study Centre to learn more about the ancient kingdom.
