The Grove is an aptly named desert oasis, one of the finer places to climb along the Colorado River. Of the climbing on the Arizona side this place has some of the highest quality and quantity of bouldering starting just out of the parking area. Boulder City climbers have been coming here since the early 90s and have put up a handful of aid, trad, and sport lines. And of course random boulder problems. The rock is mostly volcanic breccia but a thick layer of well cemented tuff runs through the canyon halfway down. A riparian area that lines a narrow section of the wash with medium-sized cotton woods and Arizona ash trees is what gave the place its name. Near the river the water that feeds this grove is forced to the surface by bedrock then funneled over a series of cliffs as the wash drops the last couple of hundred feet to the river, just across from Gold Strike Canyon. Rappelling is needed to reach the river this way but you can hike over the hill to the south before the waterfalls to the next wash, then down to reach the river and Palm Tree Hot Spring. Below the trees the canyon opens up and an old road goes north over the first rise to the Arizona gravel dumps from the construction of Hoover Dam. This is where all of the African & Native American workers during construction were sent because it was the hottest part of the job. It’s also a neat place to check out and has a great view of the dam/bridge if you go far enough around the corner. Above the gravel dump is Sugarloaf Mt. which has some bouldering and short trad lines.
