Hi there,
If you are planning to travel during May for hiking be aware that it is usually a muddy time and it is usually the least popular time for Colorado vacation.
Having said this, if you like skiing it is a great time to travel, specially to the Loveland and Arapahoe Basin Ski areas.
You will definitely want to visit the Colorado
hiking trails in Summit County where the ghost towns, gold camps and mining relics of days past can still be seen along the trails.
Some popular Colorado tourist attractions are Pike's Peak and the Soiled Doves Museum.
