As well as the above, Plodda Falls nr Tomich is one of our best and most accessible high falls - with a walkway built right-out over the falls.
If you like Golden Retrievers, stop and have a look at the monument in Tomich - Which is where they were first bred.
For Dolphins, Ft George can be good, as can the Dolphin Centre at Spey Bay but the best of all is Chanonry Point, where the deep water/current just offshore means the dolphins breech really close the shore. Check tide times though as the best sightings are always on a rising tide - which is when the fish run and the Dolphins follow them-in.
Gordon Castle Garden has an excellent play area and a good cafe/interesting garden and Logie Steading nr Forres has another good cafe, some interesting shops and easy walks to the Findhorn/Randolph's Leap. Its also where the Digestive Biscuit was first baked..!
