Keyhaven Marshes

6 miles (10 km)

This coastal cycle or walk takes you from Lymington to Keyhaven through the beautiful Keyhaven and Pennington Marshes. The path runs along a sea wall with the marshes on one side and the sea on the other. As such you are surrounded by varied and beautiful scenery for the length of the route. In the marsh area you will pass a number of pretty lagoons where you can look out for a wide variety of birdlife including Egret, Shelduck, Curlew and Heron. On the coastal side there are fabulous views of the Isle of Wight which is less than 2 miles away. Hurst Castle is also visible for most of the way - you could extend your walk by walking along the shingle spit to Henry VIII's Device Fort if you have time.
The Solent Way and the Bournemouth Coast Path long distance walking routes also run through Keyhaven so you could also continue your exercise along these paths.

The river enters the sheltered sea behind the shingle bank of Hurst Beach, and winds its way through salt marshes to the Solent. Avon Water itself rises in the heathland to the south of Burley in the New Forest.

Crabbing on the bridge at the head of Mount Lake, Keyhaven - - 505145

Photo of families crabbing on the bridge at the head of Mount Lake. The vehicles in the background are parked on the verges of New Lane (from Milford on Sea), which meets with the end of Saltgrass Lane (from Keyhaven) just off to the right. The pebbles in the foreground are on the landward side of the Hurst Beach bank. Water from Sturt Pond is channelled along the back of the pebble bank (from the right) and out into the marshes behind Hurst Spit (off to the right) where it is called Mount Lake. The many children and parents on the bridge are crabbing. Some bigger scale sea angling takes place on the seawards side of the spit, but it's not particularly safe for children due to the undertow.
