My husband and I love this park! We rented a tandem bike for $6,000 won per hour and rode along the Hangang River. It was a great way to see the city and give our exhausted feet a rest. A plus is that the back person on the tandem bike can also take photos! The rental bike shop if off the Bundang Line, exit 2 (note that this line may not be in the old metro map). There are gardens, outside gyms, volleyball courts, bat mitten nets, a rock climbing wall facility, a roller skate park, and convenient stores along the bike path. We enjoyed the breeze, watching the locals, and stopping along the way to soak in the scenery. Highly recommended!!! Even if you don't like biking, I would recommend that you check out the park for its facilities (fountains, playgrounds, deer zoo, etc).
