Biorock and Coral Reef right on the main beach is rare anywhere in the world. Here it is also free! Just make your way to the beach, hire your goggles and snorkel then enter the water at the marked locations along the beach. Do make sure you put on sunscreen or at least a t-shirt as you will be burned to a crisp within 30 minutes. The reef and bio rock is extensive so you can easily spend a day here. There are no touts or other hassles at all. It is very Wheelchair friendly too.
There is a lonely peak around 100 meters high just next to the western side of the main beach. You can see perfectly the whole coastal area from the top and if weather permits mount Ijen in eastern Jawa will appear on the horizon. On your way up you will see two temples set beautifully in the hill’s landscape. Use your natural sense of orientation or find the Gecko homestay to reach the feet of the peak. Go up by the concrete path starting with some steep run of stairs. (15 min walk)
Just a couple of kilometers east from Pemuteran is a Monkey Temple right beside the road (Pura Pulakih). The dozens of monkeys here are better behaved than those in Ubud. They make a great photo opportunity, particularly with the ocean and beach background. Locals feed them fruit but its not a good idea to put down your bag or leave windows open in parked cars.
