Consider a shorter hike, like those discussed in Bali's Backyard Adventures Beginner-Friendly Mountains Await to prepare.

Budgeting Your Trip

A trek to Semeru can vary in cost depending on whether you opt for a guided tour or trek independently. Factor in the cost of permits, transportation, accommodation, food, and gear rental. Budget around $300-$700 for a 3-4 day trek.
