Local Traveler Tips & Advice
Navigating Traffic & Weather
- CA-92 Traffic: This is the only direct road. Traffic is heaviest westbound on Friday afternoons and weekend mornings, and eastbound on Sunday afternoons. Plan extra travel time.
- Fog & Weather: Coastal fog is common, especially in summer afternoons ("June Gloom"). It can reduce visibility on CA-92. Drive with headlights on. Check Caltrans QuickMap for road conditions.
- Weekend Events: Half Moon Bay hosts farmers' markets and festivals. Parking downtown can fill up. Use the free Park & Ride shuttle on busy weekends.
Luggage & Accessibility
- Public Transit: Buses have luggage racks but limited space. Not ideal for multiple large suitcases.
- Mobility Needs: All SamTrans buses are wheelchair accessible. For door-to-door paratransit, look into Redi-Wheels (requires eligibility). Taxis/rideshaves can accommodate foldable wheelchairs.
Money-Saving Strategies
- Combo Trip: If also visiting San Francisco, consider taking a shuttle to the city first, then a separate trip to HMB, as city shuttles are more frequent/cheaper.
- Group Rideshare: Split an UberXL/Lyft XL 4-6 ways to bring the per-person cost down near shuttle prices, but with direct service.
- Rental Car Timing: Pick up your rental car early in the day for the best selection and rates. Consider renting off-airport for longer stays (may have lower taxes).
