Hi Sunil There are plenty places to go around in Karnataka like Gokarna, Hampi, Chikmagalur and Coorg. if you are planning a bike tour, we would suggest you to check out bike tour of 4 days by clicking on the link below: https://monksonwheels.com/tour/agumbe-gokarna-west-coast-adventures/
Visit Udupi and manglore. you can cover these places within 3-4 days 😁.
in Udupi must visit kapu beach, malpe beach , suverna river, and tha most amazing place is Pithrody Udyavar Beach at Udupi .
There are lots of places around Bengaluru.
For serene and calming ambience, try Chikmaglur.
If you love trekking, plan a trek to Tadiandamol in Coorg.
If you love architecture & history, visit Hampi.
Think you are a beach bum, then Gokarna beach is just the place for you.
Cheers.
