There are two major routes options you can consider. Both goes via Ernakulam city. Both routes takes about 2 hours to reach Kumarakom from Cherai.
The first route is via Cherthala and the second is Vaikom.
Route 1 (via Cherthala): Cherai Beach —-> Njarakkal —-> Vallarpadam —-> Marine Drive —-> Pallimukku —->Kundanoor—–> Aroor —-> Cherthala —-> Thanneermukkam Bund —-> Kumarakom
Route 2 (via Vaikom): Cherai Beach —-> Njarakkal —-> Vallarpadam —-> Marine Drive —-> Pallimukku —-> Kundanoor—–> Thrippunithura —-> Vaikom —-> Kumarakom
For both route 1 and 2 , you’ll be heading south of Vypin Island along the Vypin-Pallipuram road. Towards the south of the island, the road will hit a large roundabout junction. Turn left towards Ernakulam City.
You are on the Goshree Road. After crossing two large bridges you’ll enter the Bolgatty Island where you’ll see a large roundabout junction. Keep straight , you’ll cross another bridge and enter Ernakulam city center at Marine Drive. Turn right into Shanmugham Road.
This road will eventually join the MG Road. Turn right into MG road.
Keep continue on the MG Road towards Thevara, where you will turn left and join the NH47. At Kundanoor Junction you’ll join the 4 lane highway (NH47).
From here on you have two major routes to chose from, ie via Vaikom or Cherthala.
In either case you’ll be going through the slow moving Ernakulam city traffic for about 10-15km.
For Cherthala route, turn right at the junction.
From here on the traffic moves fast till Cherthala junction, thanks to the 4 lane route. The 4 lane ends near the Cherthala bypass. Leave NH47 and take the left diversion to Cherthala.
Further take the Chertala-Thaneermukkom road. After the Thanneermukkam Bund (a causeway across Vembanad Lake), the road joins the Kumarakom Road. Turn right to Kumarakom at the junction. That’s about the route via Cherthala to Kumarakom from Cherai.

Apart from the above two routes, you can try a few other diversions. The roads are generally in good conditions for all the routes. The main concern is to avoid the city traffic, around Ernakulam side.
