Set on a private beach and surrounded by peaceful countryside, Mersea Island Holiday Park has some first class facilities including an outdoor heated pool, live family entertainment, adventure play area and an on-site clubhouse.

Mersea Island is the most easterly inhabited island in the UK and is full of coastal gems like mudflats, salt marshes and native oysters.

From the private beach to the park's own boat launching facilities, Mersea Island Holiday Park is the perfect family holiday. The outdoor heated swimming pool is a real bonus, and you'll also find tennis courts, as well as an on-site bakery, shop and launderette.

The park has a good selection of two and three bedroom caravans including the Luxury Caravan 8 which has one double and two twin bedrooms.

Essex is a county full of contrasts - there are some brilliant seaside resorts but also miles of unspoilt coastline and countryside. And there's lots to see and do in the local area with museums at Colchester and Ipswich and great shopping at Braintree.

Fun Days Out in Essex

No visit to Essex is complete without a day at this popular zoo with over 250 species of animals. The enclosures are well maintained and the zoo provides a good habitat for the animals there.  The 60 acres of parkland and lakes are ideal for walking round and we are sure this day out will provide you with lasting enjoyable memories.   Some of the highlights include penguins which you can see swimming at Penguin Shores, and the elephants at Spirit of Africa.  In addition there are over 30 daily shows to attend.

This attraction is actually free of charge to enter which we think is excellent.  Located on the Southend Seafront there are over 50 rides and attractions to enjoy.  For the very daring there is a 75ft roller coaster with a more than vertical drop- not for the faint hearted!  Other highlights include the Dragon's Claw, Vortex, Scorpion, Ramba Zamba and Sky Drop.  Younger children will also find plenty of more gentle rides and attractions to keep them entertained.

A day at Great Notley Discovery Centre and Park is a fantastic way to explore the very best of Essex offering many facilities including a sensory trail, visitor centre, bistro and cycle hire centre. There are links to  over 15 miles of walking and cycling paths on the Flitch Way too. Those with young children can rent a trailer or tandem bike to make exploring fun for the whole family.

A very pleasant, relaxed sojourn.
We had a lovely break,caravan was lovely,returning in may
A lovely clean and tidy Park. Caravan was exceptional and felt like home from home. The grounds were well cared for and all the staff really friendly. Will stay again.
Great welcome on arrival and helpful staff throughout. Dog friendly with a much appreciated welcome pack for our furry friend. Caravan was clean and fresh, although signs of wear this did not detract from enjoyment or comfort. Mersea Island too had some interesting places to visit, and the site was not far from Colchester too. We were on a short break so did not find the visits too repetitive.
An ideal location for a peaceful holiday.
Had a fab time. Have booked another 2 mini breaks already.
I have already completed a TripAdvisor review giving Mersea a top review. My stay was wonderful. The unit exceeded all expectations. The welcome pack was very generous and terrific quality. The linen, in particular, was high quality white soft and fresh. Wonderful location. Very quiet and restful. If you want Butlins you'll be disappointed, in a good way. The walks and local attractions abound. I loved it.
Very friendly and helpful staff, caravan immaculate. The welcome packs for us and the dogs were very much appreciated. The only thing that we could fault the park for is the limited opening of the clubhouse however it is only a 10 minute walk to the local pub/restaurant.
Very nice caravan clean with everything needs supplied. Nice surprise were the two doggie bags waiting on arrival filled with a toy water bottle fleecey blanket and treats. Ice touch!
Great place for a quiet relax holiday. The caravan was very clean and had everything you need. The staff where very helpful and friendly. The only draw back was the club house could do with a bit of updating to match the new indoor pool.
Superb location. Caravan spotless and well equipped. Staff extremely helpful. Pool lovely. Only limitation was no cafe/restaurant facilities (though staff directed us to a nice pub and restaurant walking distance which was very good) and shop closes at 6 pm so a problem for anyone arrive later without pre-prepared meal with them. P.S. Comedian was terrible - late starting, not funny and boring. Most people left before he finished. Would rather have just had the music on.
