Boulder gets into the swing of spring (and ushers in the arts & crafts season) with the annual Boulder SpringFest on Saturday & Sunday, April 29 & 30 on the Pearl Street Mall. More than 100 artists and crafters are expected to set up booths along four blocks. Live musical performances and buskers will keep crowds entertained. Festival hours are 10 a.m. to 5 p.m. both days from the 1100 to the 1400 block of Pearl St., Boulder.
