(NEWS CENTER) - It may be the first day of fall, but the weather is looking downright summery and there is so much to do in Maine over the next couple of weekends. Don't believe us? Just ask Shannon Bryan from fitmaine.com. Here's her list of really cool stuff you can enjoy outdoors for the rest of September:

Acadia Night Sky Festival
Thursday through Sunday, Sept. 21-24
Acadia National Park
Some events free, various prices for others

There’s plenty of star gazing all weekend long, as well as speakers, photography workshops, boat cruises and a Star Party on Cadillac Mountain Saturday night. Go on a Bioluminescent & Star Gazing Paddle (7-10 p.m. each night – $55) in Castine Harbor under a blanket of stars and in the midst of bioluminescent organisms of the water that swirl and light up with every stroke of your paddle. Free park entrance days at Acadia National Park Sept. 30

Forest Bathing Walks
10 a.m. to 12:30 p.m. Sunday, Sept. 24
Hidden Valley Nature Center, Jefferson
$25, $20 Midcoast Concervancy Members

This leisurely guided walk through the woods is all about "taking in the atmosphere" and enjoying nature. You'll walk maybe a mile over the course of two hours, which means an easy-going pace and plenty of time to soak in the sights and smells.
