Important Updates:

• Returning registrants: You will need to LOG-IN to your account FIRST and then select your events.
• New registrants: Begin by selecting the Basic Registration fee (this nonrefundable $10 charge covers processing costs and gives access to ALL virtual events and one free field trip per person, as space allows). Children under 18 DO NOT have to pay the Basic Registration fee. Once the proper fee has been added, select your events. (You will be contacted if you do not select the Basic Registration fee for each person in your party). Use the shopping cart icon to view your selection(s) and check out. At checkout, you will create your NEW account. Please record your user ID and password information somewhere secure to access your account in the future. You will receive a confirmation letter via email upon completion. 
• ALL registrants are required to provide proof of full vaccination prior to the festival. Copies of proof must be emailed to [email protected] Once verified and noted, we will promptly delete your email. Read our Covid Safety Precautions here.
• We will be following, at a minimum, all federal, state, and local COVID mandates and guidelines. Masks/face coverings may be required on all in-person field trips.
• There will be no main festival hub this year. We are subsequently going PAPERLESS, so you will not be receiving anything in the mail. Please refer to our website for meeting locations, trip information, and access to your itinerary.
• Dress in layers, bring binoculars, and a reusable water bottle.
