Kochi's movement is built on a handful of pieces: the Ernakulam Junction and Town stations on the mainland, the Kochi Metro running east from Aluva through Ernakulam to Tripunithura, and the ferries that stitch Fort Kochi, Mattancherry, Willingdon Island and Vypin together across the backwaters. If you are staying in Fort Kochi or Mattancherry, a car is more hindrance than help. The streets near the Chinese fishing nets, Princess Street and Jew Town are narrow and parking is roughly Rs 30-60 an hour in the few marked bays. Most guesthouses along Bazaar Road and Rose Street offer a space, but confirm it before booking.
Arriving from the airport, the drive to Fort Kochi takes about 90 minutes to two hours in traffic, while the metro from Aluva to Ernakulam takes under 40 minutes and costs RS a handful. I would take the metro to Ernakulam, then a short auto or the ferry from the main jetty. Ferries run roughly every 20-30 minutes from around 6am to 8pm, costing coins, and the Fort Kochi-Vypin crossing is useful if you are heading to Cherai Beach. Skip the idea of driving to Vypin for sunset; the ferry saves the bridge queue.
Kollam sits on the main coastal railway line, with Kollam Junction well placed for the town and the ferry terminal at Kollam KSRTC bus stand area for the short hop to the Ashtamudi Lake jetties. From Kochi, the train takes roughly two and a half to three hours and is far calmer than NH66, which can stretch the drive to four hours. If you are flying in, Trivandrum airport is about 70km south, a drive of roughly 90 minutes on a good day. Book a hotel near Chinnakada or the lake front if you want to walk to restaurants; areas closer to Ashramam Maidan are quieter but need an auto for dinner.
Parking in central Kollam is tight, especially around Chinnakada and the clock tower. Most hotels with a compound offer free parking, so treat this as a booking filter rather than an afterthought. For the backwater day, the road to Munroe Island takes about 40 minutes and you will find informal parking near the jetty; Thangassery lighthouse is 10 minutes from town and has a small lot. I would base in Kollam for two nights and use autos for the town, keeping the car for the lake and coastal stretches.
From Kochi, two routes repay an early start. The first heads south on NH66 to Alappuzha, about 55km and 90 minutes, best between November and February before the heat builds; leave by 7am to catch the morning light on the Punnamada backwaters. The second turns east to Munnar, roughly 130km and four hours on winding ghat roads, so plan a full day or an overnight rather than a there-and-back. For a shorter run, Fort Kochi to Cherai Beach via the Vypin ferry and the coastal road takes about 45 minutes.
Kollam's best day route is the Ashtamudi and Munroe Island loop, taking in the Kollam-Schencottah canal and the mangroves, with a boat ride from one of the jetties. Allow half a day and go in the morning when the water is still. The coastal alternative runs south to Varkala, about 25km and 45 minutes, where the cliff-top path and Papanasam Beach make an easy afternoon; parking at Varkala is RS a modest fee near the north cliff. I would choose the Munroe route for quiet and Varkala for swimming.
Both districts have price bands that reward booking ahead. Kochi hotels run from RS mid-range guesthouses in Fort Kochi to higher-end properties on Willingdon Island and Marine Drive, with the best value in the shoulder months of October and March. Kollam is cheaper across the board, with lake-facing hotels around Ashtamudi and simple lodges near the station. Book a property with confirmed parking if you are driving; central Kochi parking is the single most common complaint I hear from self-drive travellers.
Skip driving between Kochi and Kollam at night, when the highway narrows and the lighting is patchy; take the train instead. Skip renting a car for central Fort Kochi entirely. If you want one booking to anchor the trip, I would choose a Fort Kochi guesthouse with parking for the first two nights, then a lake-facing hotel in Kollam for the backwaters, moving between them by train.

Do I need a car in Fort Kochi?
No. Fort Kochi and Mattancherry are walkable, and ferries link the islands cheaply. A car is useful only for day trips to Alappuzha, Munnar or Cherai. For the town itself, autos and the metro cover everything.
What is the easiest way from Kochi to Kollam?
The train from Ernakulam Junction or Town to Kollam Junction takes about two and a half to three hours and avoids NH66 traffic. Driving can take four hours. Book a seat in advance during festival and holiday periods.
Where should I park in Kollam?
Use your hotel's compound; most central hotels near Chinnakada and the lake offer free parking. Around the clock tower and Chinnakada streets, bays are scarce, so plan to walk or take short autos.
