No frills but solid seafood cafe by the Osbourne Bros Fishmongers who are based out of Leigh on Sea. Favourites include the brown and white crab cheese toastie and the scallop and bacon bun for breakfast, and a great selection of small plates for lunch. We visit from London (a 70 minute tube and train journey) to walk the dog a couple of times a year and always have a seafood breakfast / brunch here, and I've had this as the mid year round trip on the road bike a few times. Worth a visit!

Beautiful Nature Reserve to explore while hiking the coastal path. Be aware of the Adders (snakes) though. I didn't see one, but the locals I spoke to confirmed that they're there.

There is a lift on both platforms so you don’t need to carry your bike up / down the stairs.

Lovely seafood cafe with friendly staff and a rail to park your bike against, and lock if you so wish. Highly recommend the scallop and bacon brioche breakfast roll.

Managed by the Essex Wildlife Trust, Two Tree Island sits on the Thames Estuary. It is popular for birdwatching and 3.5km circular walk round the island is possible direct from Leigh-on-Sea. In the past it has been a sewage treatment works and a landfill site and is now a beautiful area of reclaimed saltmarsh.
