Experience Yosemite With a Naturalist

Join our naturalists for casual, one- to two-hour programs in Yosemite Valley! These guided programs focus on a specific topic, such as history or astronomy. If you know you’ll be there, please register ahead of time – you can reserve your spot weeks or months in advance using the links below, which will redirect you to our external adventure booking site, Flybook. Children five and under can attend our naturalist walks for free. When you are signing up, you do not need to include them in your reservation under ‘number of people’, but please do fill out a waiver for them under the ‘minors’ section.

Registration fee: $10–$25/person (see program details below). Please register in advance!

Please note: Registration for our naturalist walks does not include the $35/vehicle gate fee.
