There is no restriction on domestic travels, but people in the entire country are requested to exercise social distancing and refrain from visiting crowded and badly ventilated places.
Also, the government offers “Go to Travel” Campaign which has considerable discounts and subsidies for the people who want to travel domestically. It is a way to improve local businesses and industries which are hardly impacted by the pandemic.
Hope Corona virus ends soon, and we are able to travel overseas again.
