Bring your paddle board! This fun lake is right down the road. It has a nice 3.5 mile path all the way around it, grassy areas for hanging out, a playground and beach volleyball.
A national park less than an hour away. It is overflowing with elk and lovely mountains. Go for a hike or drive over Trail Ridge Road. Timed entry/reservations required in the summer so plan ahead.
Food vendors and all the good farmer's market things, plus live music.
