Schedule a Tour

Come visit us and see what makes CBF's Philip Merrill Environmental Center one of the "greenest office buildings in the world!"

One-hour guided tours may be requested, by confirmed appointment only, Monday through Thursday from 10 a.m.–3 p.m. The cost is $5.00 per person payable in advance upon confirmation of date and time. Because of the number of requests, a minimum of two weeks notice is required for all tour requests.

Two-hour guided group tours, with more extensive detail and discussion, may be requested. We try to reserve the third Saturday of each month for this purpose, from 10 a.m.–noon and 1:30–3:30 p.m., unless the building is otherwise in use. For this reason, we strongly suggest making your request one month in advance. The cost per person for group tours is $10.00. The minimum fee for a Saturday group tour is $150.00.

Advance, confirmed, pre-paid reservations are required for all tours.
