Nuvali and its surrounding area is perfect for biking. There are long roads and dirt trails.
But what if you don't have a bike? No worries! You can always rent.
JAPANESE BIKE
If you don't have a bike, or don't want to bring one, you can rent one by the boat ride stall at Nuvali (but it's a Japanese bike, not a mountain bike.). You may use this bike on the road. The rental is about P50/hr if I'm not mistaken.
MOUNTAIN BIKE.
Want to rent a mountain bike instead? You can rent from Sabak bikeshop in Paseo de sta rosa.
From Manila, you'll pass by Paseo de Sta Rosa just before Nuvali. Stop at Paseo de Sta Rosa, (that's across Caltex Gasoline station), and look for Sabak bike store. That's beside the back entrance of National bookstore, near Mercury drugstore. They're open from 7am to 7pm. You need to leave your driver's license and a deposit to borrow a bike.
Note: Sabak bike store is now closed, but there's a sportshop near Turks shawarma that rents out mountain bikes for children and adults.
Rental fee itself P700/day, P500/half day). You may call Sabak Sta Rosa at (049)5411396 to reserve.
