The Strood
The B1025 crosses the Strood to reach Mersea. Higher tides can cover the road. Check the live camera and tide information before you commit to a journey, especially around spring tides.
By car
From Colchester, follow the B1025 south through Peldon and across the Strood. After the crossing, turn towards West Mersea for the town and harbour, or towards East Mersea for Cudmore Grove. There is no alternative road crossing if the Strood is flooded.
On busy summer weekends Coast Road can fill quickly. The larger car parks away from the waterfront are often the easier option, followed by a short walk.
By train
The island has no railway station. Colchester is the principal rail interchange for many arrivals, but check the bus stop and connection you need before choosing a train. The final leg is by bus, taxi or a pre-arranged lift.
By bus
First Bus lists the 55 and 68/68A services serving West Mersea, and 67, 69 and 69A routes for East Mersea. East Mersea services are limited: the published 67 timetable includes Thursday-only journeys, so do not assume there is a daily direct bus. Check the day, direction and return trip with First Bus before setting off.
Timetable routes checked against First Bus on 13 October 2026; operators may change services.
For a car-free trip, West Mersea is more straightforward than East Mersea. An out-and-back bus journey to the eastern end of the island needs careful planning, especially outside summer.
By bike
Cycling onto Mersea uses the same road crossing as cars. The island's lanes can be attractive to ride, but they are also narrow and can be busy in summer. High tide still matters: a bicycle is not a reason to enter flood water.
West or East Mersea?
For a harbour-and-food day, aim for West Mersea. For Cudmore Grove, open coast and a quieter start, head east after the Strood. Deciding that before you arrive prevents unnecessary island driving on narrow roads.
Visiting without a car
West Mersea is the simplest car-free destination because buses from Colchester reach the village and much of the waterfront, beach and High Street can then be covered on foot. Allow more time than you would for a city journey and check the current timetable before setting out.
East Mersea takes more planning. The seasonal foot ferry can create a useful route from Brightlingsea or Point Clear when it is operating, but bus and ferry timings should be treated as part of the journey rather than an afterthought.
The bus also uses the Strood, so exceptionally high water can affect public transport as well as cars.
For journey planning, including the exact weekday-only East Mersea services and the effect of Strood flooding on buses, use the dedicated Mersea without a car guide.
