Tipping on a fishing trip has the same general rule as tipping the waiter, with 10 to 20% being a common practice. It's a good idea to start with 15% and go up or down depending on how satisfied you are with the trip. Keep in mind that guides spend hours preparing for a trip. Success on a difficult day usually means having to dig deep and work hard to overcome high tide, bad weather, lack of cooperation from fish, or any of the myriad factors that make the game of fishing what it is.

So what happens at the end of a day of great fishing when you get out of the river and get rid of your waders? Get ready to part with the guide who paddled with all his heart, tied dozens of flies to your leader, gave you good advice on how to take your offering to the right place on the current coast, prepared a spectacular lunch on the beach and even managed to take a good picture of yourself with that huge trout just before it slips out of your hands and falls back into the river.
