Cycling Osaka: Minami Temma Park and Osaka Castle Park by Bicycle

We plan to cycle two parks in Osaka following this 10-kilometer route.

First, we take the train to HUBchari Dinana Matsuya Building (center of the above map screenshot) where we rent bicycles for the day. That is where our half-day bicycle adventure begins.

9:00am
Bike North to Minami Temma Park 南天満公園.
Bike up the park along the riverside until you reach the Osaka Mint Museum.

10:00am
Bike to Osaka Castle Park 大阪城公園.
Explore the whole park instead of taking the usual tourist path from the station to the castle. Ride through the plum grove, the apricot trees and past the fountain. Find a spot to sit and enjoy being in nature.

11:30am
Bike to Saizou 菜蔵 for lunch.

1:30pm
Bike to HUBchari America-mura and return bikes.

We spend the rest of the day on foot checking out Shinsaibashi-suji Shopping Street, Ebisubashi-suji Shopping Street, two of Japan's famous discount stores: Matsumoto Kiyoshi and Don Quijote, and the also famous Ebisubashi Bridge (where the Glico running man is). The we eat dinner at Oretachi no Curry Ya, which is just a short walking distance away.

Has anybody tried cycling through Minami Temma Park and Osaka Castle Park? I'd love to hear your opinions and suggestions, because I'm not quite sure our legs will hold up in Shinsaibashi after a 10-kilometer bike ride!
