Most of the locations on this itinerary are within walking distance, so your feet will be your primary mode of transportation. If you choose to rent a bike or kayak, the rental facilities are within the walking distance of the Hermosa Beach Pier. If you need to use a car, there is plenty of public parking in the area. Keep in mind that parking can be expensive and scarce during peak hours. Consider using a ride-sharing app or public transportation if you want to avoid the hassle of parking.
If you have more time, you can visit the Roundhouse Marine Studies Lab and Aquarium, which is a small but informative aquarium where you can learn about local marine life. If you have less time, you can skip the Farmer's Market or the Art Walk. If you decide to take a bike ride, make sure to wear comfortable clothes and sunscreen, and bring a water bottle. If you are kayaking, make sure to wear a life jacket and follow the safety instructions.
