Chocolate Lab Expeditions

Chocolate Lab Expeditions Chocolate Lab Expeditions is a fly fishing outfitter, guiding in Montana & San Martin de los Andes, Patagonia, Argentina

Chocolate Lab Expeditions (CLE) offers near year-round guided fly fishing trips, operating in Montana and Patagonia, Argentina. For the months of June through August, we guide on the Missouri, Big Hole, Beaverhead, and Madison. CLE also offers some of the best fishing in all of Patagonia. Owners Ron and Vanessa Sorensen have been guiding and outfitting anglers in Northern Patagonia since 1996, building a reputation for dependable excellence as they have shared their passion for fishing Patagonia over the years. Vanessa's three generations of family history in San Martin has enabled CLE to access properties and establish a great staff of local Argentines. Ron offers a long guiding career that started in '91 on the Madison River, then for Mike Lawson from 1992-2002, and finally under his own Montana license starting in 2003. CLE was featured in the movie "Rise" by Confluence Films, and multiple times in the Angling Report, including a feature article in the October 2010 issue. Ron was twice covered by Columbia Country's "Fishing The West", in Flyfishing & Tying Journal's Spring 2011 Guide Profile, various articles in Trout and Salmon, Gamefisher, FlyFishing & Fly Tying, and others. CLE offers a range of fishing options by utilizing a mix of public and over 260 miles of private access waters on over 12 local rivers, seven estancias (fishing ranches), private leases, and various overnight camp floats. World famous rivers such as the Malleo, Chimehuin, Collon Cura, and Limay serve as the focus of CLE's operation. CLE also fishes many lesser known rivers that fish well seasonally. This area of Patagonia offers very diverse types of fishing — from sight casting to rising trout on spring creeks, to stalking big browns on crystal clear mountain streams, throwing large dries on faster freestones, and fishing large productive tailwaters. From the often prolific mayfly and caddis hatches of the early summer (December through early February) and fall (late March through April) to the inch worm infestation and minnow runs during mid-summer, this rich area always has something to offer the visiting angler. Trips of any length (typically 6-10 fishing days) are custom designed for each client based on fishing preferences, trip timing, and budget. Many clients have taken advantage of mixing time at the top notch estancias with their miles of private access water and the more simple but quality overnight camp trips. The CLE team offers excellent guides, great meals and wines, and top quality equipment. They are one of the few outfitters in Argentina operating a full fleet of drift boats, which might not sound like much until you spend a day hung up on the straps and buckles of a raft. Whether you are enjoying a stay at one of the first class fishing estancias, fishing out of the charming town of San Martin de los Andes, or on a wilderness overnight float trip, CLE brings excellence, value, and a passion for insuring your trip is the best possible.
