Without hikes, humans would never know the joy of sunlight on skin, the caress of a breeze on the cheek, or the emotional power of coyote slam poetry. Immerse yourself in these joys with today’s Groupon: for $49, you get a guided beginner or moderate half-day hike from Hike In Phoenix (up to a $99 value).

Certified in first aid and CPR and well-versed in the area’s history and wildlife, the seasoned guides at Hike In Phoenix lead groups of 10 or fewer inquisitive hikers through safe and informative treks through the Sonoran Desert. Each half-day hike begins in the early morning to dodge the sun, meeting in different places depending on the route scheduled. Groups then traipse along trails that twist and turn through Phoenix's wilderness for three to four hours. Guides spin fact-laden tales about the desert while their gaggle of sojourners bounce along paths suited to the group's collective tastes and abilities. Hikers can choose between a beginner- or moderate-level excursion, ensuring that their trips befit their skill levels so they don’t wind up stuck upside-down on a cactus.

Each hike is different, sometimes boasting picturesque views of the city, glimpses of the hushed serenity of raw nature, or chances to help gangs of fugitive roadrunners escape to the state line. Included snacks and refreshments sustain stamina, and a souvenir cap or bandanna rebuffs the sun's rays. At each rest stop, guides test the group's knowledge with desert-trivia games that whip grey matter into shape while its bodily shell takes a break. Hike in Phoenix also organizes guided excursions for wheelchair users and anyone else seeking more accessible trails.

Though Hike In Phoenix offers discounts for teenagers, seniors, and more than one hiker registering at once, this Groupon still represents the best deal available.
