Your legal right is to “pass and repass along the way”. You may stop to rest or admire the view, or to consume refreshments, providing you stay on the path and do not cause an obstruction. You can also take with you a “natural accompaniment” which includes a pram, or pushchair.
You can also legally take a manual or powered wheelchair (mobility scooter) provided you follow the regulations for taking these vehicles on ordinary roads. However, there is no guarantee that the surface of the path will be suitable for pushchairs and wheelchairs.
You can take a dog with you, but you must ensure it is under close control. Note that there is no requirement for stiles to be suitable for use by dogs.
