521 Nongeop Saengtae Cheheomjang in Guri is an agricultural ecology experience center where visitors see and touch insects, reptiles, and fish. Hands-on activities include touching stag beetles, larvae, and rhinoceros beetles, and putting a hand into a beehive. A visit, including a snack, takes about one to two hours, and the center runs bee classes, gecko distribution, and has staff on hand. The space is small, so there is limited to see if you stay longer than two hours.
