When demand peaks
Kaiser Permanente's Fontana hospital employs 9,677 people on round-the-clock shifts, so midday walks book in Sierra Lakes and Summit Heights all year. Of 101,764 workers, 75,025 drive alone and 14,459 commute over an hour, most down the 10 or the 210. Fontana Unified starts August 6, 2026, and walks drop over its winter break, December 21 to January 8.
