Set up the Trail. Place the game board in the center, shuffle the eight Trail Site tiles, and place one face up on each Trail Site. Add alternating Sun and Water Weather tokens beginning with the second Trail Site.

Prepare the Seasons and Shutterbug. Shuffle the Spring, Summer, and Fall Season tiles separately and reveal one of each. Roll the Trail Die and place the Shutterbug token beneath the matching Trail Site.

Set up Parks, Gear, and Canteens. Shuffle the Park deck and reveal three Parks. Shuffle the Gear deck and reveal three Gear cards. Mix the Canteen tokens, create the draw pile, and reveal three Canteens.

Set up each player. Choose a Hiker color, place both Hikers at the Trailhead, and take the matching Player Board. Each player also receives a random Canteen and a Campfire token.

Choose Passions and a starting player. Give each player a Passion card. The player who most recently visited a National Park receives the First Hiker token and takes the first turn.

Move one of your Hikers. On your turn, choose one Hiker and move it forward as far along the Trail as you like. Hikers can never move backward.

Stop at a Trail Site and take its action. Trail Sites let you collect resources, interact with Parks, gain Canteens or Photos, buy Gear, or roll the Trail Die. If you are the first Hiker to reach a Site containing Weather, collect that Weather token as well.

Use your Campfire when necessary. Normally you stop at an unoccupied Trail Site. You may extinguish your Campfire to share a Site with another Hiker. Your Campfire is relit at the end of the Season.

Collect resources and visit Parks. Mountains, Forests, Sun, Water, and Wildlife are used to pay the costs shown on Park cards. When taking a Parks action, either reserve a Park for later or spend resources to visit as many Parks as you can afford. Visited Parks earn points.

Improve your hike with Photos, Canteens, and Gear. Trade resources for Photos, fill Canteens with newly gained Water to trigger their benefits, and purchase Gear that provides useful abilities throughout the game. Gear benefits can generally be used once per turn when their conditions are met.

Complete your Passion. Each player has a personal Passion objective. Once you complete it, flip the card and choose between a special Gear-style ability for the rest of the game or an End Game scoring bonus.

Reach Trail's End. When a Hiker reaches Trail's End, choose a Parks, Photo, or Gear action there. The first player to choose each action during the Season also receives the corresponding bonus. Once both of your Hikers reach Trail's End, you are finished for that Season.

Start a new Season. Once every Hiker reaches Trail's End, award the Season Bonus, return Hikers to the Trailhead, empty Canteens, relight Campfires, reshuffle the Trail Sites, add new Weather, and refresh the Gear Market. After Fall—the third Season—the game ends.
