We start the last day ride with a transfer to the park center, where we immerse into the forest by bike; after 18 km cycling through the national park, we visit the Endangered Primate Rescue Center. Afterward, we cross Dong Giao pineapple plantation with many stops along local farmlands, taste the fresh pineapple, and finish the ride in Tam Diep. Take a transfer to Tam Coc for lunch. Take a boat paddling, through three caves under the big mountain, between two green rice fields and great limestone. We'll transfer back to Ha Noi in the late afternoon.
