Do you mean 5 Jyotirlingas located within Maharashtra (e.g., Bhimashankar, Trimbakeshwar, Grishneshwar + others) or the 5 closest Jyotirlingas across India? Covering widely spread Jyotirlingas in 6 days requires long flights/drives.
Tell me whether you prefer driving yourself, a private car with driver, or public transport, and the exact dates you plan to travel (so I can check temple timings and opening days).
