Mount Rinjani isn't just a mountain; it's an epic adventure that promises breathtaking sunrises, a mystical crater lake, and a profound sense of accomplishment. As the second-highest volcano in Indonesia, this trek in Lombok requires serious preparation. This comprehensive guide will equip you with the essential tips needed for a successful and unforgettable journey.
Choosing Your Path: Senaru vs. Sembalun Route
Your Rinjani experience will be heavily influenced by the route you choose. There are two main starting points:
- Sembalun Route (East Lombok): This is the most popular choice for those aiming for the summit (3,726m). It starts with a gentle trek through a vast savannah, but the final ascent to the summit is a steep, challenging scramble on volcanic scree. This route is recommended if reaching the peak is your primary goal.
- Senaru Route (North Lombok): This route takes you through a dense, shaded tropical forest. The climb is more consistent and gradual compared to Sembalun's final push. While you can still reach the crater rim for spectacular views of the Segara Anak lake, reaching the absolute summit from here is much more difficult and less common. It's ideal for trekkers who want to focus on the crater lake and scenery.
Essential Fitness and Altitude Preparation
Do not underestimate the physical demands of this trek. To prepare, you should focus on:
- Cardiovascular Training: Incorporate running, cycling, or swimming into your routine at least 4-6 weeks before your trip to build endurance.
- Strength Training: Focus on leg strength with squats, lunges, and calf raises. A strong core is also vital for stability on uneven terrain.
- Stamina Building: Go for long hikes, preferably with some elevation gain and while carrying a weighted backpack to simulate trekking conditions.
- Acclimatization: Altitude sickness is a real risk. Plan a trek that allows for gradual ascent (a 3D2N or 4D3N package is much better than a rushed 2D1N). Stay hydrated by drinking plenty of water, avoid alcohol, and listen to your body.
