If you are new to fly fishing and you just want to catch a fish, then South Boulder Creek is the perfect choice for you. The flows are perfect and there is no angling pressure. I made my way up to Eldorado Springs and fished inside of the park. You can fish the creek anywhere in the park or the canyon. Right now it is a dry fly haven, I never even tied on a nymph.
Parachute Adams, Puterbaugh Caddis, X2 Caddis, Yellow Sally Dries, Foam Ants and Beetles all in size #12-16 are working well. The fish are not tippet shy, 4X is just fine. Throughout the afternoon I saw PMDs, Caddis, Drakes, Midges, Yellow Sallies and hoppers all through the river. Right now the river is perfect for a 2wt or 3wt rod. Most of the fish are smaller, I didn’t catch anything over 12 inches, but they made that up in numbers. You can easily go up there and expect to catch a couple dozen fish.
