Those who want to break up their beach time with some healthy exercise will want to venture to Kintamani. Located near the island's northeastern coast, 40-some miles north of Kuta, Kintamani is a gorgeous region that boasts a towering (and active) volcano and a large lake. Both landscape features are named "Batur," and their pairing makes for dramatic scenery. The two also offer an array of adventures for intrepid travelers. You can hike up Mount Batur for a bird's-eye view or take a boat out on the water. Many travelers recommend hiring a local guide once you reach one of its small lakeside towns or arranging a daytrip through your hotel in advance. You also shouldn't miss Pura Ulun Danu Batur, one of Bali's most important temples, which is located on the lake's southwestern shore.

Recent visitors highly recommended a sunrise hiking tour, though many noted the trek is a bit challenging. Those who completed the journey said it was worth it for the views and serenity from above. Bali Sunrise Trekking and Tour receives favorable reviews from past visitors, as does the Mt Batur Sunrise Trekking company.

The best way to get to the Kintamani area is via private car, direct shuttle or daylong tour from a major tourist center in Bali. Due to the elevation, the weather here can be noticeably cooler than at the beaches, so pack layers. Kintamani has several villages that can provide affordable accommodations and dining options, should you wish to stick around for lunch or stay overnight.
