I need a word to describe a meeting or conference or other event which was the opposite of boring due to the variation of activities there.*

German language has abwechslungsreich, literally rich-of-changes. All dictionaries I have available recommend diversified, but then, more precise definitions all meander around "diversifying a business" etc., and that's quite a different thing.

So, what would native speakers use to describe a meeting that is pleasant for attendants because there is enough (but not too much) variation in activities?

Note: abwechslungsreich is very often used also for landscapes. Would

Bulgaria has a diversified landscape.

be a good sentence? My feeling is: rather not. But what could be used instead?

*) I do not mean interesting, which one could claim is the primary opposite of boring. Interesting is regarding the contents of a meeting and the attitude of an attendant towards it. Abwechslungsreich however is about the agenda of the meeting.

The German abwechslungsreich means not only ‘varied, diverse’ but that such variety is interesting or entertaining. There is no single English word that does both, so you have to use two adjectives instead of one:

We have a varied and interesting programme, including speakers, bring and buy, raffle, coach outings and walks in the New Forest, Strawberry Tea, mince pies and sherry, Christmas Lunch and social activities. — New Forest Branch

Vegetarian food can be as varied and interesting as non-vegetarian food. This time of year, look at what vegetables are in season and take your inspiration from there. — Agony Chef, Westmoreland Gazette, 30 Dec. 2017.

The work of a Garden Designer is varied and interesting and occasionally requests arrive for something out of the ordinary. — Janine Crimmins, Garden Design, 19 Oct. 2014.

The concert consisted of many traditional songs together with some more modern renditions and the addition of some African songs made a very varied and interesting evening. — Scarborough News (UK), 6 May 2011.

You can raise the entertainment factor with fun and varied:

Create a fun and varied hot dog bar with all your favorite add-ons for the best summer grilling party! — Belly Full, 15 July 2015.

Or stick the fun part in an adverb:

Cannes Market. Located along one of the Côte d'Azur's best gourmand streets, Forville Market offers visitors to Cannes a delightfully varied eating and food shopping experience among its produce and flower stalls. — Radisson Blu Hotels

These examples hardly exhaust the possibilities, but the point is that in English you’ll likely need one word for variety and one for fun, not just one as in German that does double duty.
