Yi Fen is an excellent guide and modified our plan based on what we wanted to see. We only had a short day at the port and she made the most of it. She and her driver picked us up at Keelung Harbor and we went straight to Yehliu Geo Park. We arrived when the park opened and really enjoyed this amazing place to ourselves before the tour buses arrived. This is a must see place! Then we went to all the recommended sites in Taipei that we could fit in. Wish we had more time to stay! Overall, we had a great day with Yi Fen exploring around and really enjoyed our yummy lunch. Some of the best food we had in Asia. Thank you for a great day! Rick & Andrea
