Once in the hotel, take an hour or two to have lunch and freshen yourselves up a bit. Head straight over to Minneriya National Park after that and make sure to reach maximum by 4 PM. You might feel tired, but I promise the herds of elephants drinking water from the breathtaking lake in the middle of the park will more than make up for it. It is peaceful beyond what my words can describe, so I will not even try. This should take you till about 6:30 PM and by 7 you can be back to your hotel for an early dinner. Not much goes on in the city after sunset. Make use of this to catch up on some sleep and invigorate yourself for a busy Day 2!
