3. Share Yugen Earthside

The highest accolade is earning word-of-mouth referrals. If you have friends, family members, or colleagues who would enjoy our trips, please send them our way! Or, spread the word on social media to reach a broader audience. Tag @yugenearthside so we can boost your post!

4. Use our Affiliate Links for Trip Basics

If you love the part of trip planning that involves researching, scouring ideas, and pouring over ratings, or if you simply like the flexibility that comes with booking each trip component on your own, you can still support us by using our affiliate links. Affiliate links do not change the price you pay, and using the links will generate a small amount of commission revenue for Yugen Earthside.

Accommodations: Booking.com

Book accommodations including hotels, apartments, guesthouses, and more on Booking.com.

🌱Sustainability Tip: After your initial search, use the "Travel Sustainable Properties" filter on the left-hand side. Properties can earn one to three leaves, with three leaves representing the most sustainable properties.

Book Now

⚠️Greenwashing risk! Booking's identification of 'sustainable properties' is relatively new, having launched in November 2021. Since then, Booking rolled out the three-leaf system, and more detailed explanations of what is behind each 'leaf'. Companies with only one leaf may not be doing much more than declaring an intention to be more sustainable. Two leaves represent more robust actions, and three leaves generally represent a third-party sustainability certification. The system is not perfect and there is still a lot of room for improvement.

See our popular blog post on alternate sites for booking eco-friendly and sustainable accommodations.

Car Rental: Auto Europe

Driving tours can be a great way to get off the beaten track, travel independently and at your own speed, and visit more rural and remote areas. This can be a great way to help with 'tourism dispersal' (visiting places outside of tourist hotspots, where your tourism dollar might be more appreciated by locals), and give you a more unique travel experience.

Auto Europe has about 24,000 locations in over 180 countries and has a Better Business Bureau rating of A+.

🌱Sustainability Tip: We recommend renting an electric or hybrid vehicle if possible!

Activities: Viator (a TripAdvisor Company)

Viator offers things to do, tickets, tours, and attractions. Viator is a subsidiary of TripAdvisor, meaning they share inventory. A great option for museum visits, day trips, city tours, show tickets, and more.

🌱Sustainability Tip: Check the details of guided excursions and tours and look for how many guests the activity can accommodate. Smaller group activities (i.e. one small van with 8 guests) can feel more intimate and give you a better experience than a big bus experience with 40+ travelers.

Book Now

Activities: GetYourGuide

GetYourGuide offers sightseeing tours, attractions, excursions, and things to do. A direct competitor to Viator, you can find cooking classes, tourist attractions, and all kinds of sports, cultural, food, and nature activities.

🌱Sustainability Tip: Check the details of guided excursions and tours and look for how many guests the activity can accommodate. Smaller group activities (i.e. one small van with 8 guests) can feel more intimate and give you a better experience than a big bus experience with 40+ travelers.

We know... we know! While hesitant, here's why we opted to include these links. As a completely digital company, Yugen Earthside does not have a storefront nor do we hold physical inventory. But, we're still constantly discovering, using, and testing sustainable travel products. This is an easy way to share our curated selection with you.

  • Travels to destinations with harder access to clean water
  • Camping, biking, backpacking, trekking, walking, and other outdoor trips
  • Emergency preparedness
