This place is gorgeous. Not many inexpensive ways to experience the arts in southern maryland to the level that Annmarie provides.

Beautiful installations all through the wooded paths, art classes for kids and adults, special events quite often- and the (air conditioned) galleries are great as well. Gift shop has a ton of neat items, from toys and cute fun baubles to full on art pieces from the featured artists.

The Artsfest every September is a great two day event with 150-ish artists displaying their wares, you can find everything from jewelry to 8 foot tall driftwood sculptures! Stained glass, Ceramics/pottery, of course painters and photographers galore... Lovely fabric and silk artists, metalwork and others I've forgotten to mention!
Many of those artists also sell things at the Makers Faire events on Saturday mornings during their season (website does have the info) so if you missed Artsfest you can still see a lot of beautiful things for sale!

Definitely a place worth visiting if you're in the area, expect to spend a good amount of time exploring.
