Society of American Travel Writers (SATW)
The oldest travel journalism organization in the US. Open to American and Canadians. To qualify for membership as blogger you need to average 10,000 unique visitors per month over a 12 month period and 1 member to sponsor you. You can also gain membership through freelancing or by winning a Lowell Thomas Award.
British Guild of Travel Writers (BGTW)
The premier travel journalism group for the UK/Ireland. To qualify as a blogger you must have “a blog that is updated at least fortnightly and has at least 3,000 visitors a month and a Mozrank of over 4”.
Australian Society of Travel Writers (ASTW)
It is unclear if/how bloggers can join. Membership requirement seem to be based on the number of words/photos published per year.
Travel Media Association of Canada (TMAC)
Travel media group for Canadians. They only just started accepting bloggers. Membership requires 2 members who are sponsors and you have to meet a certain number of qualification points. Just doing a brief check for myself, I easily qualified and only 10 of the necessary 50 points involve traffic.
North American Travel Journalists Association (NATJA)
Not actually a member run organization. Best known for its annual awards competition. NATJA awards are easier to win than Lowell Thomas Awards because there are many more categories and they split print/digital awards. Qualification is very easy as only have to submit 8 articles from the last 12 months.
American Society of Media Photographers (ASMP)
Great member benefits. Have to be a professional photographer and have 2 members sponsor you. One of the most professional organizations I’m a member of. Lots of professional development.
The International Food Wine & Travel Writers Association (IFWTWA)
A global organization. Membership requirements are not that hard if you post on a regular basis and have been doing so for at least a year.
North American Nature Photography Association (NANPA)
A North American organization, but open to members globally. Not a professional organization per se. It is open to all photographers and there are no membership requirements. They have a very active Facebook group (I am a member).
Outdoor Writers Association of America (OWAA)
Bloggers can join and the only requirement is a website “that is updated with original content at least twice a month and receives 500 AUVs (Average Unique Views) per month over a 12-month period, or generates income.” That is a pretty low threshold.
Midwest Travel Writers Association (MTWA)
There is no explicit requirement allowing bloggers to join. Their website only says: “Other travel-related media will be considered on a case-by-case basis.” This really seems more like a club than anything else. THREE sponsors are required, and there is a membership requirement that you attend the meetings. I am not aware of any people who primarily identify as bloggers who are members.
Bay Area Travel Writers (BATW)
Organization is (obviously) centered around the San Francisco Bay area. Open to bloggers. Website states that blogs must “Consistently average a minimum 3,000 absolute unique visitors per month (AUVs) over one year”. Your blog must also make money directly or indirectly.
North American Snowsports Journalists Association (NASJA)
Membership is actually handled by the regional groups (East, West, Midwest). To qualify as a blogger you must have been blogging for 1 year, proof of income, 4 updates per month, and 5,000 pageviews per month.
Professional Photographers of America
Despite the name, there are membership categories for Canadians and International members. There are no requirements per se other than paying dues. They offer a LOT of online courses and online “degrees”. It is mainly for photographers who are running a photography business. Good member benefits on insurance.
