Cyclists must give way to walkers and horse-riders on bridleways. Generally, it's good to be friendly, say hello and share the space kindly.
Leave gates and property as you find them or follow instructions on signs. When riding in a group, ensure the last person knows how to leave the gates.
Follow signs and keep to marked paths -- get to know the signs and symbols and what they mean.
Check your route and the weather conditions, and ensure you have the appropriate kit.
If in doubt, an excellent source for helpful info and safety advice is Sustrans, who are all about keeping you safe when out on two wheels.
