I made a booking for 5 people just two days before we wanted to go. The agency immediately reached out on WhatsApp to confirm and ask a few more questions. Our driver Jackie arrived right on time, and was wonderful - driving safely, giving guidance, and even providing umbrellas for when it rained. Our booking was for 8 hours which was, enough to cover Yehliu, Jiufen, and Shifen Waterfall. We arrived back in Taipei a little after the agreed time and were fully prepared to pay an additional fee for the extra time, but instead got mango jelly as a farewell gift from Jackie. Great experience overall and I can highly recommend!
First of all, the shopkeepers were very friendly. The guide who led the hike to Hill 401 on April 11th was very friendly and professional, and the instructor who brought up the rear was also very friendly. 1. This is really challenging; assess your own abilities, as the hot and humid weather will increase the difficulty. 2. Bring an extra set of clothes; you'll be soaked through after the hike, and your underwear will be completely drenched. 3. Bring a small handheld fan; the dense forest areas are windless, damp, and stuffy, with few well-ventilated spots. 4. Bring a parasol; you'll need it for the island loop. You won't need it for the hike itself, but it can be used as a walking stick. 5. Some steps are very slippery; wear shoes with good grip because it's very damp, and the fresh fallen leaves are sap-covered, making it very slippery. 6. Fog is normal, but without fog, the clear blue sky would be unbearably hot. 7. Get a massage when you get back; definitely massage your legs and stretch, otherwise your legs will be very sore. 8. We set sail promptly at 8:00 AM and returned to Wushi Port around 2:30 PM. We didn't see any dolphins or whales on the way there or back. The boat trip was half an hour each way, so we didn't need to take seasickness medication, but we still saw one or two people vomiting.
I participated in whale and dolphin watching in Yilan for the first time. The crew were very kind and worked hard to find a pod of dolphins with us. Unfortunately, we didn't see any whales, but we were able to see dolphins up close, which made it very satisfying. Be careful, as the front row of the boat gets wet with seawater.
