Gokarna known as beach town of Westindia and Karnataka is a summer spot to visit. Will share a Tripoto link written by a traveller pertaining to complete travel guide in Gokarna. See if it is suitable for your travel. https://www.tripoto.com/karnataka/trips/things-to-do-in-gokarna Here is all you could do too
Start with Mahabaleshwar temple
Then on travel to Kudle beach Come back to om beach
Taste some beach cuisine in Himalayan cafe Take rest Evening by 5pm reach om beach then on take a boat to Paradise beach
Stay for a night there tasting some yum seafood and shop for some beach items. Either night you see the lovely coastline else next day morning reach before sunrise Indulge into swimming. Yana caves is 25km away from this beach while Mirjan fort is 10km away. You can club both for a visit. Come back to the city to taste food in namastey cafe at Om beach. Evening you can beach trek to belekan beach, small hell beach, and shop at Gokarna for some souvenirs and must taste is Kallusakkare a sugar candy. This above itinerary I did when I travelled for two days to Gokarna. If your travel is beyond two days you could explore Koti Tirtha
Kumta Sirsi falls
If you would like to do a little offbeat , here's the plan! Stay at Kumta Om bodhi retreat/Silver sand resorts - I'll bet you won't regret your stay in these bunch of resorts which are at Kumta. It is only 20km to Gokarna.. While you stay here , you can explore Mirjan Fort and go to Gokarna via boat from Aghanashini.. They will take you to all famous beaches of Gokarna ,but not to the main temple and all.. If you want to visit main temple , ask them the suggestions as how it could be done These boat riders comes with packages along with water sports , the number will be put up in the banner once you enter any of the resorts !! I have visited Gokarna separately like covering Main temple and the 5 beaches and as well as have done this . The best experience was from Kumta !!!! if you have more time , try to cover both in one shot . It's definitely worth it!
