    REGISTRATION/PAYMENT NOW LIVE, LINK AT BOTTOM

    Mosaic is excited to announce a SUMMER weekend in cottage country at Camp Gesher.
    What’s different about this event?
    ITS IN THE SUMMER. We typically only get to rent a camp after the season ends.
    WE HAVE THE WHOLE CAMP TO OURSELVES.

    When: Friday August 21, 2026 to SUNDAY AUG 23, 2026. 3 nights.

    We can arrive at camp as early as 11am on Friday and stay as late as after lunch on SUNDAY. So make plans to take Friday off work!!!

    Accommodation: Cabins and cottage-style rooms. Pricing ranges from NEW LOWER PRICES $370 to $500 per person for the weekend including food!

    Camp Gesher is located on Pringle Lake. It is in the Land O’Lakes cottage area and not far from Bon Echo Provincial Park. It is about a 3 ½ hour drive from Toronto and about 2 ½ hours from Ottawa.
    There is a range of options for accommodations in the camp from 12 person cabins where we will only put a maximum of 4 people, to several cottage type rooms suitable for two people comfortable sharing a double-sized bed. You are also welcome to bring a tent for your accommodation if you prefer.

    The camp is kosher—all inputs are kosher and there are separate milk and meat dishes. However, there is only one dishwasher used which alternates between milk and meat dishes. There is no kosher supervision on site. Gesher can accommodate a range of dietary requests including gluten free, vegan and vegetarian.

    Activities will include lots of lakeside lounging, swimming, canoeing**. In
    August you can expect warm weather and warm water! Bon Echo Park with it’s petroglyphs and scenic Mazinaw lake are just up the road.** We will offer an opportunity for you to take canoeing lessons, included in the cost of the weekend. Want to learn the j-stroke? Want to learn the basics of soloing? This will be the weekend to enjoy that in addition to campfires, camaraderie, and family style meals.

    Accommodations for single person registration:
    We have 4 possible accommodation choices for individuals. You will be asked if you want to room with specific people. We will do our best to meet your requests but we cannot fully guarantee this. All pricing for these options are per person.
    Accommodations for couples or two people who want to share a double bed:
    We have 6 options in total for "couples" or two people willing to share a double bed. All options are in vintage cabins on the property. Expect plywood walls, no insulation, like a typical vintage cottage rental. There is one washroom per cabin so you might be sharing that washroom with up to 6 others depending on the number of bedrooms in that cabin. All pricing for these options is per room.

    We need a minimum of 30 people signed up by July 30 at 9am to be able to run this event. We will cap attendance at 65 people. So register now and save your spot!

  • Civil War Historical Hike @Mt. Zion/ Gilbert's Corner parks

    Civil War Historical Hike @Mt. Zion/ Gilbert's Corner parks

    Mt. Zion Historic Park, 40309 Little River Tpke, Aldie, VA 20105, Aldie, VA, US

    *this walk occurs the same day as daylight savings ends, clocks "spring forward" 1 hour, please heed caution*

    In honor of America250, trek this landscape 'rifled' with Civil War (and more) history via this 3mile easy hike that has meager elevation changes and is GRASSY from meadowland terrain. Pace: 3mph. The trek traverses Mt. Zion Historic Park as well as Gilbert's Corner Regional Park, sites of a "calvary skirmish" that occurred in July, 1864.

    The hike first explores the Mt. Zion Church & Cemetery, a setting situated at the crossroads (now roundabout) of the Old Carolina Road (read on) and highway US50. Mt. Zion acted as a Union field hospital, barracks, & prison during the nearby Battle of Aldie in June, 1863. Just over a year later, Confederate forces ambushed the cemetery grounds as Union troops were on the move, ensuing in a melee of many mounted soldiers, some buried directly in said cemetery. While most graves are inside a barricaded brick wall, some rest on the outside, indicating segregation since these burials were African-Americans. Though the church itself is technically closed, Park Services or Church Staff might be on-site for open visitation.

    After egressing from this eternal home the trek observes an opulent overlook of the Bull Run Mountains (pictured), then proceeds along the historical OLD CAROLINA ROAD[BED] that began as an Indian trail, which was remarked in 1825 when residents extolled [the] Marquis de La Fayette and President Monroe, who were traveling on a "grand tour". During the 1930s, highway US15 was constructed for modernizing this trail. The hike encircles a meadow following this, eventually returning to the Church to learn more about this rendezvous point of rampage via interpretive signage & illustrations.

    Latter of the Circuit crosses highway US50 into Gilbert's Corner park which oscillates between meadow meandering and woodland wandering-- with a gander by a garden too. Expect some unique flora & fauna here as well as a any remnants of the Old Carolina Road before concluding back at the Church.

    NOTES:
    1. Trail Forecast= MAP; NOVA parks YouTube Video | Wear Boots! Pack the bug repellent; possible shade advisory (sunglasses, hat).
    2. Post- social @Gilbert's Corner Farmers Market.
