Super fun to ride bikes to the monument with my kids. They were ages 12 and 9 and we were easily able to do all the monuments and the White House in the 4 hour time frame. Had a great time! Pro tip bring a phone holder for your bike so it’s easy to navigate while riding.

Diego is an excellent guide – fun, energetic, and full of interesting information that makes the trip even more special. What really stands out is his creativity: he has music prepared for every “wow” moment and plays it at just the right time, which truly elevates the whole experience. He even acts like an FBI agent at times, adding a unique sense of humor and originality to the tour. He is very professional, as he says every sentence in English and then in Spanish, so everyone can easily follow along. Even though the trip includes quite a bit of driving, the scenery and overall experience are absolutely beautiful and worth it. Special praise also goes to the driver, who was excellent – safe, pleasant, and professional throughout the entire journey. Overall, highly recommended! Greetings from Croatia 🇭🇷
