With the start of the summer recreation season, and the snow starting to melt quickly at the higher elevations I thought the Outdoor Recreation Infromation Center would be a good choice for the linking the week site. The ORIC can be a useful resource around the year but most people venture out hiking or backpacking in the summer and the website has a good list of hikes in the Colorado area.
In addition to the online information, you can talk to the ORIC staff at the Denver REI flagship store near downtown and they can also give you ideas for places to visit as well. Most people just past by the area on the way to the cashiers, but next time you are there and are looking for some ideas for your next hike be sure to stop by and see what ideas they may throw your way. The service is free but they may suggest you get a map for that area if you don’t have one, but that is something you should have with you anyways when getting on the trails no matter the length of the hike.
