Head on down to Mandal River and spend an afternoon strolling along the water's edge. There's something about being by a river that makes you feel calm and peaceful.
You'll be spoiled for sightseeing choice when staying in Ramnagar. Mandal River is an ideal place to begin here, but there are lots of other worthy spots to discover. Corbett Tiger Reserve, and Shri Hanuman Dham are near the flowing body of water and will fill in your day nicely.
