Aspen Trail Finder: Great for finding a new trail based on a specific set of criteria.
Aspen Trail Finder is a comprehensive trail index, built for anyone looking for adventure outdoors — walkers, hikers, runners, road bikers, mountain bikers, equestrians and dog lovers. It is a resource for trails in Aspen, Snowmass, Basalt, Carbondale, and Glenwood Springs. The creators don’t like telling people which trails to do or want users only looking at what experts say are the best. There’s adventure finding new trails. Everyone’s different and different sports provide different ways to experience and enjoy a trail. The app and website allow users to search by activity (hiking, biking, running, snowshoeing, cross-country skiing, uphilling, and more), difficulty, and distance. If that is too many options, you can also select a random trail, random park, or random site to check out. It also lists trail conditions with information on seasonal closures, weather, and much more trail and road info.
Pitkin Outside: Great for topo maps and seeing how different trails connect in a geographic area. Offline caching is supported.
Pitkin Outside is a project of Pitkin County Open Space and Trails and is a resource devoted to recreation and ecology in the Roaring Fork Valley. There are two versions: Trail Finder and Eco Finder. Trail Finder is an interactive map focused on recreational opportunities in the Roaring Fork Valley, including trails, climbing, river access, public fishing and more. Eco Finder features a collection of ecological studies and data, compiled in one place for easy access and research purposes. Trail Finder offers information on both summer and winter trails and allows you to toggle between seasons.
Note: This app is specific to Pikin County, so it covers Aspen, Snowmass, and parts of Basalt, extending up Independence Pass as well as parts of the Crystal River Valley.
Transit (App only): Great for determining how much time until the next local or BRT bus, and getting a bike to explore town.
The Transit app aggregates and maps real-time public transit data in the Roaring Fork Valley and in over 125 cities worldwide, so when you leave the valley, you can still use it in major areas such as New York City, Chicago, Washington D.C., and Los Angeles. Locally, the app is best for getting RFTA (Roaring Fork Transportation Authority) bus information, including accurate real-time predictions, simple trip planning, step-by-step navigation, service disruption notifications, and departure and stop reminders. It also integrates with the local bikeshare WE-cycle, allowing you to locate a bike, unlock it from your phone, and find open docking stations when you are done. While only available during select major events (typically in Aspen), car sharing requests for Uber and Lyft can also be done through the app.
COTrex: Great for learning about trail conditions, which agency manages a trail and contributing to crowdsourced. Offline caching is supported.
The Colorado Trail Explorer (COTREX) is a project Colorado Parks and Wildlife (CPW) and Department of Natural Resources, in partnership with organizations at every level statewide. COTREX offers the most comprehensive trail map available for the state and is built atop data from over 230 trail managers. Trails can be viewed by allowed uses on the map, browse featured routes, download offline maps, record trips and notes in the field, complete challenges to earn badges, and share your experiences with the community. COTREX is your gateway into Colorado’s magnificent outdoors — whether online or on the app. Users can record trips and report field notes, which not only help other outdoor enthusiasts, but also help to inform trail managers about current conditions on the ground.
