Pasak Jolasid Dam is now a major tourist attraction for people travelling in Lopburi Province. For us, we went there for lunch before heading on towards Lopburi city to see the monkeys. It is possible to do this loop as a day-trip from Bangkok. Though, to make it a more worthwhile day, it is a good idea to do it between November and January when the sunflower fields are blooming with bright yellow colours. A recreational park has been created at the southern end near the dam. There are plenty of food vendors here and you can buy some food to eat as a picnic along the waterfront. There is often a cool breeze here and it is a great place to come to escape the heat of the day, There is also an interesting museum with free entry which details the history of the reservoir as well as the social history of the local inhabitants.
