Is it okay to go hiking on a cloudy day without sunscreen?

It is always a good idea to wear sunscreen when going hiking, even on cloudy days. The UV rays from the sun can still reach you on a cloudy day, and without sunscreen, you can still risk getting burned. Make sure to bring along a sunscreen with at least SPF 30 and reapply every couple of hours.
