The walk along the seafront at Crammond is one of the most beautiful and accessible (very wide and flat path surface) I've done.
Accessible Parking ✅
Accessible Toilet ❌ (Costa coffee is a 5 minute drive away with amenities)
Play Park ❌
Accessible Equipment in Play Park ❌
Cafe (take a left and walk round to Crammond harbour) ✅
The carpark is really busy because it is such a popular place to go. There are a couple of disabled bays but just know you might need to find somewhere else to park.
The one negative about this location, and it's a huge one, there is no accessible public toilet. The nearest one I could find was at a costa coffee shop a 5 minute drive away.
The clip below follows the route from Crammond Island along towards Granton Harbour. I turned back at the point I did because I was cold but I'm led to believe the path just keeps going in a similar fashion.
