The combination of nature, bike riding and tour of the city appealed to us. We are close to 50 and typically take leisurely 10 mi rides at home, and we managed the approx 17 mile ride through SF just fine with Dandyhorse. They have customized a bike ride that provides a great tour of the city with minimal hills and plenty of breaks. The beach and garden visits and the interesting city historical spots were fun and informative, and time to enjoy them is provided. You will see the best views of the city on this tour! They pay attention to every detail, from having our bikes and water bottles labeled for each rider, snacks in our bags, extra sunscreen and sunglasses, and water to a drink before we got started. Even finished the tour with local beers in their garden and recommendations for further enjoying the communities we toured. My BF is gluten-free and Dandyhorse arranged a delicious lunch full of gluten free choices.
