This is the easiest and by far the most popular route. From Probolinggo, it's 28km to Sukapura, then another 14km to Ngadisari and another 3km to Cemoro Lawang. Minibuses run all the way to Cemoro Lawang from Probolinggo. Just before Cemero Lawang, you must pay the 2100Rp entrance post.
As with mountain scaling anywhere in Asia, it is all important to be at the top of Gunung Bromo for the impressive sunrise.
