The gap between ski season and summer in Colorado is affectionately known as mud season.
Why it matters: If you head into the mountains, you'll want to be prepared. The snow is melting and the ground is thawing, meaning many hiking trails are boggy at best.
Yes, but: It's also a great time to visit because it's not crowded.
If you go: Here are some tips to make it fun.
Plan wisely. Lower elevation and south-facing trails will dry out faster than others. Also, respect trail closures.
Watch your step. If the trail looks particularly wet, avoid it. Hiking muddy trails increases erosion and leads to side trails that hurt the ecosystem.
Beware of the weather. Spring in Colorado is unpredictable, particularly at higher elevations, so bring layers suitable for cold or wet conditions.
Go south. Great Sand Dunes and Mesa Verde national parks are great places to visit in the spring before temperatures get too hot.
Pack accordingly. Micro-spikes for icy sections, gaiters for muddy patches and a pair of boots will make the trip a little easier.
