80s or 90s movie where a couple are by a river in the woods hunted by a killer(s)

I saw this movie I the 90s when I was a kid so it could possibly filmed in the 80s or 90s. I remember this couple got a tour guide to go somewhere in the woods and they took horses there, they stopped at a river and the tour guide was killed and I just remember it being night and people or a person had torches trying to find the couple and they were hiding by the river.
