The route is reasonably accessible for most as the walking is mainly on large (but sometimes muddy) easy-to-follow tracks, but the last few metres getting to a couple of the caches may be a bit more interesting (but not hard or serious) - hopefully families will enjoy it. As this is in the woods this is a route of small or regular sized caches too - except one micro! (I couldn't resist)!
Tricky trig? No not really! Located a few metres from the trig.
Number four of the series and another small tub with a possible clue for the bonus in. In stones on the ground.
After you find it you need to head straight across the top (follow the main path again) but keep to the left of where your GPSr is pointing to number five where you will pick up a path that heads down in between two rocky crag bits to get to number five. This is still the main path.
Many thanks to The Woodland Trust for allowing me to place this series.
