The Kaybiang Tunnel is on the road between Ternate, in Cavite, and Nasugbu, in Batangas. The road follows the coast and is known for its views of the sea. Riders from Manila make a full-day loop of it.
The ride
The Ternate-Nasugbu Road is 30.229 km long, according to Wikipedia. The tunnel is 300 m long and opened in 2013. The road is paved.
Getting there and back is what makes the day long. One rider’s blog records a full loop from Manila and back at about 226 km, with about 1,517 m of climbing. That is a hard day for anyone. The figures come from a single ride, so treat them as a guide.
A shorter ride that starts in Cavite, with the bike brought there by car, would be more moderate. We do not have a measured distance for that option. Plan it on a map with someone who has ridden it.
Good to know
- Bring front and rear lights and switch them on before the tunnel. Take off dark glasses as you enter.
- The drier months, December to May, are the sensible time, following the national weather pattern.
- For the full loop, start before dawn and plan your food and water stops in advance. A day this long needs steady eating and drinking.
- These are open public roads. Ask riders who have done the loop recently about traffic and road works.
- Try the full loop only after you have finished rides of 100 km or more in comfort. The Laguna Loop is a shorter test of the same kind.
- Agree on a plan with your group for anyone who cannot finish: where to stop, and how to get home.
A long day in the sun asks a lot of the body. Read riding in the heat before you go.
