Outdoor Ethics


Puerto Rico Bio Bay Tours LLC. is passionate about the outdoors, nature, flora, fauna, history, culture, and the wild areas that allow us the opportunity as interpretive guides to teach and share the secrets that are held within these delicate wonders of nature!

One of our greatest gifts is the ability to bring guests into wild locations and during a short window of time, spark interest in new and trending outdoor ethics! Much of this is done by example, as outfitter and custodians of the environments we work in, we practice Leave No Trace. Setting up our Puerto Rico tours with endless forethought as to leave the natural area as we found it or better, bringing only the needed things in with us and make sure we bring them all back out!

We hope to spark your interest in Leave No Trace and the outdoor ethics that will expand your knowledge allowing you to understand that it does take responsible acts and planning to keep our natural wonders pristine and intact for many others to enjoy and generations upon generations to experience!

The Leave No Trace Seven Principles:


Plan Ahead and Prepare:

  • Know the regulations and special concerns for the area you’ll visit.
  • Prepare for extreme weather, hazards, and emergencies.
  • Schedule your trip to avoid times of high use.
  • Visit in small groups when possible. Consider splitting larger groups into smaller groups.
  • Repackage food to minimize waste.
  • Use a map and compass to eliminate the use of marking paint, rock cairns or flagging.

Travel and Camp on Durable Surfaces:

  • Durable surfaces include established trails and campsites, rock, gravel, dry grasses or snow.
  • Protect riparian areas by camping at least 200 feet from lakes and streams.
  • Good campsites are found, not made. Altering a site is not necessary.
  • In popular areas:
    • Concentrate use on existing trails and campsites.
    • Walk single file in the middle of the trail, even when wet or muddy.
    • Keep campsites small. Focus activity in areas where vegetation is absent.
  • In pristine areas:
  • Disperse use to prevent the creation of campsites and trails.
  • Avoid places where impacts are just beginning.
  • Dispose of Waste Properly:

    • Pack it in, pack it out. Inspect your campsite and rest areas for trash or spilled foods. Pack out all trash, leftover food and litter.
    • Deposit solid human waste in catholes dug 6 to 8 inches deep, at least 200 feet from water, camp, and trails. Cover and disguise the cathole when finished.
    • Pack out toilet paper and hygiene products.
    • To wash yourself or your dishes, carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap. Scatter strained dishwater.


    Leave What You Find:

    • Preserve the past: examine, but do not touch cultural or historic structures and artifacts.
    • Leave rocks, plants and other natural objects as you find them.
    • Avoid introducing or transporting non-native species.
    • Do not build structures, furniture, or dig trenches.
    Leave No Trace Principles: Plan ahead and prepare, be considerate of others, respect farm animals and wildlife, travel and camp on durable ground, leave what you find, dispose of waste properly, minimise the effects of fire. Practising a leave no trace ethic is very simple: Make it hard for others to see or hear you and leave NO trace of your visit

    Minimize Campfire Impacts:

    • Campfires can cause lasting impacts to the backcountry. Use a lightweight stove for cooking and enjoy a candle lantern for light.
    • Where fires are permitted, use established fire rings, fire pans, or mound fires.
    • Keep fires small. Only use sticks from the ground that can be broken by hand.
    • Burn all wood and coals to ash, put out campfires completely, then scatter cool ashes.

    Respect Wildlife:

    • Observe wildlife from a distance. Do not follow or approach them.
    • Never feed animals. Feeding wildlife damages their health alters natural behaviors and exposes them to predators and other dangers.
    • Protect wildlife and your food by storing rations and trash securely.
    • Control pets at all times, or leave them at home.
    • Avoid wildlife during sensitive times: mating, nesting, raising young, or winter.

    Be Considerate of Other Visitors:

    • Respect other visitors and protect the quality of their experience.
    • Be courteous. Yield to other users on the trail.
    • Step to the downhill side of the trail when encountering pack stock.
    • Take breaks and camp away from trails and other visitors.
    • Let nature’s sounds prevail. Avoid loud voices and noises.
