Tips for Visiting Lake Biwa #

- If you want to experience local culture and smaller harbors, start or finish a Biwaichi (Lake Biwa loop) bike route from Otsu or Omihachiman and use the smaller ferries to reach Chikubu Island for a less crowded island visit.
- Skip the busiest weekend picnic spots by exploring the lake's eastern and northern shores (Nagahama, Hikone and Omi‑Maiko) where historical towns, castle views and quieter beaches are easily accessible by train.
