Sights - depends on what time of year you are there and what sort of Activities your Family likes... Start with Visits to Durango. Park and Walk the Old Town Main Street. We've got Restaurants for all Tastes, and Bars for all Kinds (from Trendy to BrewPub to Cowboy to Blues to Punk to Biker). We've got 5 (count them - FIVE) Local Breweries with too many Lagers and Ales and IPAs and Stouts to count - AND 2 of them brew some of the BEST EVER Real Root Beer (not just for Kids). Browse the Galleries (buy that $5K statuette if you must) and Antiques Shops. Hit the T-Shirt Shops for all the Shirts and Hoodies you could ever want. Stick your head in to any of the Sporting Goods Shops - the folks behind the counter will not only be able to tell you the best Hikes for Wildflowers or Wildlife but also be able to tell you Which Flies are Good on which Streams AND which are already fished-out by the Local Experts. Stop at any of the Rafting Kiosks and book a 1/2-day or Full-Day Rafting Trip (Family-friendly or bigtime Wild Water). And by all means, stop in to Maria's Bookstore - not only is it a great quaint Bookstore but the first Bookcase and wall-rack behind it are FILLED with Guidebooks for the Local and Regional Hikes and Wildlife and Scenic Trips. You can get a lot more tourist info at the Visitors Center at Santa Rita Park, or trails and wildlife info at the San Juan Public Lands Office just West of downtown. Beyond Downtown, there are Hiking and Mtn Biking Trails in almost every direction / ridge / valley / mountain that you can see (that's part of what the Visit to Marias Bookstore or the Visitor Center or the SJ Public Lands Office are good for). The Durango & Silverton Railroad Terminal is right at the south-end of Downtown - you likely heard/saw the Steam Locomotive and Train already. The DSRR runs to Silverton via the forested Animas River canyon where you see the River beside you and cut through the high wilderness peaks above you. There is also the Chama & Toltec RR about 2.5hrs away at Chama NM, where you traverse over the Continental Divide through Aspens and Tundra to the Horizon while peeking into the river canyons below. Both are unique, and both are quite worth the 3/4 to full day commitment. There are several area Lakes and Reservoirs, at McPhee and Vallecito Marinas you can rent powerboats or pontoon boats. There are also numerous "Rivers" and creeks to splash in or try your hand at Fishing. Throughout the Summer (not Spring) the High Country Backroads routes are filled with Wildflowers, as well as historic Mines and Mills and other ruins (some are car-friendly graded roads while others require High Clearance or actual 4x4). And once you look elsewhere than Durango, the towns of Pagosa Springs and Silverton and Ouray and Telluride and Cortez and even Creede and Gunnison and Moab and Crested Butte are all within a daytrip distance - and each worthy of a Day worth of exploration.
